FIGURE 5 in Aspects of the taxonomy of the Kalanchoe daigremontiana species complex (Crassulaceae subfam. Kalanchooideae) and associated interspecific hybrids in southern Madagascar, with the description of a new nothospecies, K. ×descoingsii (=K. laetivirens × K. tubiflora)
FIGURE 5. Some bulbiliferous kalanchoes in the Arboretum d'Antsokay, Madagascar. A–C. Kalanchoe laetivirens. D–F. Kalanchoe ×descoingsii. Both taxa show some abaxially pinkish leaves, especially towards the margin, almost acaulescent pseudo-rosulate growth habit, and apically obtuse to rounded leaves. While K. laetivirens is otherwise of green colouration and showing broad rounded-triangular leaves that are unspotted abaxially, K. ×descoingsii is of a darker colouration and shows narrowly elliptical, abaxially maculate leaves. Photographs: Jun Ikeda.

FIGURE 4. Phenological transitions in the leaves of Kalanchoe ×descoingsii (R. Shtein 501). A. Transition from the distal, attenuate, oblanceolate leaves, to the medial, auriculate oblong leaves. B. Medial leaves showing the pink, distinctly blotched petiole, pink margins, and central veining pattern, minute adaxial maculation, and the overall bright light green leaf colour. The leaf blade is oblong, roundtipped, minutely auriculate at the base, strongly dentate, and well-developed bulbil pedestals with abscission scars can be seen in the apical ½. C. Medial leaves showing the round-obtuse apex, oblong leaf blade shape, and colouration. D. Leaf in the basal ¼ of the stem, close to wilting and abaxially striped, showing spathulate pedestals subducting large denticules all around the leaf blade margin with a few bulbils still attached, a deeply auriculate leaf blade base, as well as a similar colouration as in F, but with the blade overall a darker olive green. E–F. Comparative view of the K. tubiflora-like bulbils that are still attached to a leaf, and rooted bulbils with the appearance of those of K. laetivirens. F. Basal, obtuse-tipped leaf with darker colouration, a generally oblong leaf blade shape, but showing the characteristic widened and auriculate base. The dark colouration and below-the-leaf position of the still-attached bulbils is notable, compared to the light green, K. laetivirens-like bulbils in the background. Each bulbil is attached to a dedicated pedestal (obscured from view by the leaf blade margins). Photographs: Ronen Shtein.

FIGURE 1. Comparison between Kalanchoe ×houghtonii Morphotypes A, B, and C, and K. tubiflora. A. Kalanchoe ×houghtonii Morphotype A, a form growing variously in Israel and is indistinguishable from K. ×houghtonii 'J.T. Baldwin', showing large, lanceolate leaves, and large, medially inflated, magenta, K. tubiflora-like flowers; the inflorescences are large and distinct. B–C. Details of the leaf (B) and salmon-pink flowers (C) of a similar form of K. ×houghtonii Morphotype A; material growing invasively in Porto Covo, southern coastal Portugal. D. The large, orange-red, medially rounded flowers of K. tubiflora on an indistinct peduncle, also growing invasively in Portugal. E–F. The two cultivars of K. ×houghtonii Morphotype B: K. ×houghtonii 'Hybrida' with a decussate leaf arrangement (E) and K. ×houghtonii 'Pink Butterflies' with a tricussate leaf arrangement (F), both showing ovate leaves. G. Kalanchoe ×houghtonii Morphotype C, showing linear leaves with ≥10 denticules along the leaf margins, i.e., more than the number diagnostic for K. tubiflora, and a lower number of bulbil pedestals. H–J. The sub-terete leaves of three distinct clones of K. tubiflora, all apically showing 6–8 margin denticules per leaf and an equal number of bulbil pedestals. Photographs: Gideon F.

FIGURE 6 in Aspects of the taxonomy of the Kalanchoe daigremontiana species complex (Crassulaceae subfam. Kalanchooideae) and associated interspecific hybrids in southern Madagascar, with the description of a new nothospecies, K. ×descoingsii (=K. laetivirens × K. tubiflora)
FIGURE 6. Some bulbiliferous kalanchoes in the Arboretum d'Antsokay. A–B. Kalanchoe daigremontiana showing deeply peltate, longtriangular leaves that are apically acute. Abaxially, the leaves are greyish, and maculate with dark blotches especially towards the margins. The overall khaki green colouration and spotted petiole may suggest some influence from K. tubiflora. More conspicuously admixtured plants are known from other localities in the Toliara and Onilahy regions of Madagascar, as discussed in the text. C–E. Kalanchoe tubiflora showing some variation in the overall colouration of the plants. It is not known which of the forms of K. tubiflora that are cultivated in the Arboretum are native to the Toliara region, and which were introduced from elsewhere in Madagascar. Photographs: Jun Ikeda.
FIGURE 2 in Aspects of the taxonomy of the Kalanchoe daigremontiana species complex (Crassulaceae subfam. Kalanchooideae) and associated interspecific hybrids in southern Madagascar, with the description of a new nothospecies, K. ×descoingsii (=K. laetivirens × K. tubiflora)
FIGURE 2. Comparison between two forms of Kalanchoe ×houghtonii Morphotype D, which is alternatively treated as K. daigremontiana and potentially represent K. daigremontiana × K. ×houghtonii. Both forms lack the large, medially inflated, orange, red or magenta flowers of the other K. ×houghtonii Morphotypes discussed in this paper, the leaf arrangement generally remains decussate, and the leaf blade base is peltate when plants reach maturity. A–D. A form originating from the Toliara region, southern Madagascar, showing saddle-shaped, peltate leaf blade bases on mature leaves, subentire margins on leaves of young plants, abaxial maculation patterns resembling those of K. daigremontiana, and uniquely, sepals that are barely fused. E–H. Kalanchoe 'Parsel Tongue', reportedly a garden hybrid that arose spontaneously, showing funnel-shaped peltate leaf blade bases on mature leaves, dentate margins even on leaves of young plants, uniquely granular abaxial maculation patterns distinct from those of any other kalanchoe of the K. daigremontiana species complex, and sepals that are fused for half of their length, as observed in K. daigremontiana. Also note that these two forms differ significantly in the length of their corollae. Photographs: Ronen Shtein.

FIGURE 12. A. Bernard Marie Descoings (1931–2018), when visiting Mr Jean-Luc Billouet's succulent collection in April 2012. B. When aloe specialist Dr (h.c.) Gilbert W. Reynolds, visited Madagascar in the 1950s, Descoings, then a young man in his mid-20s, accompanied and assisted him (Reynolds 1958: 6–7, 146, Fig. 100, Reynolds 1966: ix, 515, Fig. 543). Descoings here stands next to a large specimen of Aloestrela suzannae (Decary 1921: 26) Molteno & Gideon F.Sm. in Smith & Molteno (2019: 5). The original of the black-and-white image was likely held in Herb. PRE along with parts of the archives of Reynolds, but is apparently no longer extant.

Adaptive divergence and the evolution of hybrid trait mismatch in threespine stickleback
<p>Selection against mismatched traits in hybrids is the phenotypic analogue of intrinsic hybrid incompatibilities. Mismatch occurs when hybrids resemble one parent population for some phenotypic traits and the other parent population for other traits, and is caused by dominance in opposing directions or from segregation of alleles in recombinant hybrids. In this study, we used threespine stickleback fish (<i>Gasterosteus aculeatus</i> L.) to test the theoretical prediction that trait mismatch in hybrids should increase with the magnitude of phenotypic divergence between parent populations. We measured morphological traits in parents and hybrids in crosses between a marine population representing the ancestral form and twelve freshwater populations that have diverged from this ancestral state to varying degrees according to their environments. We found that trait mismatch was greater in more divergent crosses for both F<sub>1</sub> and F<sub>2</sub> hybrids. In the F<sub>1</sub> the divergence--mismatch relationship was caused by traits having dominance in different directions, whereas it was caused by increasing segregating phenotypic variation in the F<sub>2</sub>. Our results imply that extrinsic hybrid incompatibilities accumulate as phenotypic divergence proceeds.</p>

Analysis of ancestry heterozygosity suggests that hybrid incompatibilities in threespine stickleback are environment-dependent
<p>Hybrid incompatibilities occur when interactions between opposite-ancestry alleles at different loci reduce the fitness of hybrids. Most work on incompatibilities has focused on those that are 'intrinsic', meaning they affect viability and sterility in the laboratory. Theory predicts that ecological selection can also underlie hybrid incompatibilities, but tests of this hypothesis using sequence data are scarce. In this article, we compiled genetic data for F<sub>2</sub> hybrid crosses between divergent populations of threespine stickleback fish (<em>Gasterosteus aculeatus</em> L.) that were born and raised in either the field (semi-natural experimental ponds) or the laboratory (aquaria). Because selection against incompatibilities results in elevated ancestry heterozygosity, we tested the prediction that ancestry heterozygosity will be higher in pond-raised fish compared to those raised in aquaria. We found that ancestry heterozygosity was elevated by approximately 3% in crosses raised in ponds compared to those raised in aquaria. Additional analyses support a phenotypic basis for incompatibility and suggest that environment-specific single-locus heterozygote advantage is not the cause of selection on ancestry heterozygosity. Our study provides evidence that, in stickleback, a coarse—albeit indirect—signal of environment-dependent hybrid incompatibility is reliably detectable and suggests that extrinsic incompatibilities can evolve before intrinsic incompatibilities.</p>
Patterns of hybrid seed inviability in perennials of the Mimulus guttatus sp. complex reveal a potential role of parental conflict in reproductive isolation
<p>Genomic conflicts may play a central role in the evolution of reproductive barriers. Theory predicts that early-onset hybrid inviability may stem from conflict between parents for resource allocation to offspring. <span>Here we describe <i>M. decorus;</i> a group of cryptic species within the <i>M. guttatus </i>species complex that are largely reproductively isolated by hybrid seed inviability (HSI). HSI between <i>M. guttatus </i>and <i>M. decorus </i>is common and strong, but populations of <i>M. decorus </i>vary in the magnitude and directionality of HSI with <i>M. guttatus</i>. Patterns of HSI between <i>M. guttatus </i>and <i>M. decorus, </i>as well as within <i>M. decorus </i>conform to the predictions of parental conflict: firstly, reciprocal F1s exhibit size differences and parent-of-origin specific endosperm defects, secondly the extent of asymmetry between reciprocal F1 seed size is correlated with asymmetry in HSI, and lastly, inferred differences in the extent of conflict predict the extent of HSI between populations. We also find that HSI is rapidly evolving, as populations that exhibit the most HSI are each others' closest relative. Lastly, while all populations are largely outcrossing, we find that the differences in the inferred strength of conflict scale positively with </span><span>p</span><span>, suggesting that demographic or life history factors may influence the rate of parental conflict driven evolution. Overall, these patterns suggest the rapid evolution of parent-of-origin specific resource allocation alleles coincident with HSI within and between <i>M. guttatus </i>and <i>M. decorus. </i>Parental conflict may therefore be an important evolutionary driver of reproductive isolation. </span></p>
Subspecies and Distribution. S. s. scrofa Linnaeus, 1758 — W Europe, from Denmark, Germany, Poland, and Czech Republic to N Italy and N Iberian Peninsula; possibly also Albania. The taxonomic status of animals in Austria, Switzerland, Slovenia, and Slovakia is unclear but presumably these populations are included in scrofa, as are the populations of Sweden, Finland, and the Baltic states. However, restocking of once depleted populations, for example in Italy, has likely involved the introduction and mixing of this subspecies with other subspecies, such as attila. S. s. affinis Gray, 1847 — S India and Sri Lanka. S. s. algirus Loche, 1867 — Tunisia, Algeria, and Morocco, on the coastal side of the mountains or in the low montane areas. S. s. attila Thomas, 1912 — Hungary, Ukraine, C & S Belarus, Romania, Moldova, and S Russia towards the N flank of the Caucasus, but not including the Transcaucasian countries of Georgia, Armenia, and Azerbaijan. The range possibly extends as far S as the Mesopotamian Delta in Iraq, in which case it would likely include W & SW Iran, and possibly E Turkey and Syria, where it borders with lybicus. Such a range could not be easily reconciled with a statement by Groves that "the difference between pigs from N and S of the Caucasus is quite striking; Transcaucasian boars are certainly not attila." This subspecies may also extend into C Asia and include Kazakhstan, Uzbekistan, and Turkmenistan, but no data exist to support this. S. s. baeticus Thomas, 1912 — originally described from Coto Donana, S Spain, and later merged with meridionalis; also S Portugal. Unless evidence is found that these Italian and Iberian populations are the relics of a much larger formerly contiguous range, this subspecies should be kept as distinct. S. s. coreanus Heude, 1897 — Korean Peninsula. S. s. eristatus Wagner, 1839 — Himalayas S to C India and E to Indochina (N of the Kra Isthmus). S. s. davidi Groves, 1981 — the arid zone from E Iran to Gujarat, including Pakistan and NW India, and perhaps N to Tajikistan. S. s. leucomystax Temminck, 1842 — main Is ofJapan (Honshu, Shikoku, Kyushu, Nakadori, Hiburijima, Tojima, Kushima, and other smaller Is). S. s. lybicus Gray, 1868 — Bulgaria, Greece, Turkey, Syria, Jordan, Israel, Palestine, in the past also in Lybia, and Egypt. The former Yugoslavia was included in its range, which would suggest that now Slovenia, Serbia, Croatia, Bosnia and Herzegovina, Montenegro, and Kosovo are within the range of this subspecies, although the exact boundaries are unclear. Pigs from Albania have been assigned to S. s. scrofa. S. s. majori De Beaux & Festa, 1927 — C & S Italian Peninsula. S. s. menidionalis Forsyth Major, 1882 — Corsica and Sardinia, with the proviso that the two populations are very likely to be introduced or feral. S. s. moupinensis Milne-Edwards, 1871 — China, S to Vietnam and W to Sichuan. S. s. nigripes Blanford, 1875 — the flanks of the Tianshan mountains in Kyrgyzstan and NW China (Xinjiang). An animal photographed in NE Iran (Golestan) looked like this subspecies. S. s. nukiuanus Kuroda, 1924 — Iriomote, Ishigaki, Okinawa, Tokunoshima, Amamioshima, and Kakerome Is in the Ryukyu chain in extreme S Japan, though some of these populations have hybridized with introduced domesticates. S. s. sibiricus Staffe, 1922 — Mongolia and Transbaikal (S & E of Lake Baikal). S. s. tawvanus Swinhoe, 1863 — Taiwan. S. s. ussuricus Heude, 1888 — far E Russia and the Manchurian region (China). Korean populations were previously included in this subspecies, but based on new evidence, the Korean taxon seems more similar to moupinensis. S. s. vittatus Boie, 1828 — Malay Peninsula, S of the Isthmus of Kra, the offshore islands of Terutai and Langkawi, Sumatra, Riau Archipelago, Java, Bali, and a range of smaller islands around these, including Babi, Bakong, Batam, Bawean, Bengkalis, Bintan, Bulan, Bunguran, Cuyo, Deli, Durian, Enggano, Galang, Jambongan, Karimon (Riau Is), Kundur, Lagong, Laut, Lingga, Lingung, Mapor, Moro Kecil, North Pagai, Nias, Panaitan, Payong, Penang, Pinie, Rupat, Siantan, Siberut, Simeulue, Singkep, Sugi, Sugi Bawa, Telibon, Tinggi, Tuangku, and the Tambelan Is. This species was originally present from the British Is in the extreme W, through Eurasia from S Scandinavia to S Siberia, extending as far E as Korea and Japan, and SE into some of the Sunda Is and Taiwan. In the S the species ranged along the Nile Valley to Khartoum, and N of the Sahara in Africa, more orless following the continental coasts of S, E, and SE Asia. Within this range it was absent only from extremely dry deserts, e.g. the driest regions of Mongolia and in China W of Sichuan; and alpine zones, such as the high altitudes of Pamir and Tien Shan. In recent centuries, the range of S. scrofa has changed dramatically because of hunting and changes in available habitat. The species disappeared from the British Is in the 17" century, from Denmark in the 19" century, and was greatly reduced in range and numbers in the 20" century from areas as distant as Tunisia, Sudan, Germany, and Russia. Following these severe declines, there were some slight population recoveries in Russia, Italy, Spain, and Germany in the mid-20™ century, and natural and assisted range expansions in Denmark and Sweden. The species has also been inadvertently reintroduced in various locations in the Great Britain via escapees of mixed origin from commercial farming enterprises. Ex-S. scrofa stocks also occur as introduced feral populations in various other parts of the world, including Australia, New Zealand, the eastern Malay Archipelago, and in North, Central, and South America. In all of these areas they are now generally recognized as a major pest. in Suidae

Distribution. Sulawesi and adjacent Is (Buton, Kabaena, Muna, Peleng, Lembeh, and on some of the Togian Is); thought to be extinct on Selayar I. Pigs have been widely domesticated through the Indonesian archipelago and beyond. This primarily involved the Eurasian Wild Pig (S. scrofa), but also S. celebensis, the only other species of pig successfully domesticated. Mitochondrial DNA studies of the dispersion of these domesticated forms agree on three major dispersal events, two involving S. scrofa and one S. celebensis. Evidence supports an early human-mediated translocation of S. celebensis to Flores and Timor and two later, separate human-mediated dispersals of domestic pig through islands of SE Asia into Oceania. In addition to Flores and Timor, S. celebensis is also thought to occur in its domesticated form on Halmahera, Lendu, Roti, and Savur Is, and even on Simeulue and Nias Is to the W of Sumatra and far from its island of origin, Sulawesi. In the Moluccas, and possibly elsewhere in this region, introduced S. celebensis are thought to have hybridized with other introduced pigs of S. scrofa derivation, and apparent hybrids between these species are now reported to survive on a number of islands, including Salawatti, Great Kei, Dobu, Seram, Ambon, Bacan, Ternate, Morotai, and New Guinea. It is also reported that in the 19" century the sows of domestic pigs in Sulawesi frequently mated with wild animals, after which they returned to their villages. in Suidae
Distribution. Sulawesi and adjacent Is (Buton, Kabaena, Muna, Peleng, Lembeh, and on some of the Togian Is); thought to be extinct on Selayar I. Pigs have been widely domesticated through the Indonesian archipelago and beyond. This primarily involved the Eurasian Wild Pig (S. scrofa), but also S. celebensis, the only other species of pig successfully domesticated. Mitochondrial DNA studies of the dispersion of these domesticated forms agree on three major dispersal events, two involving S. scrofa and one S. celebensis. Evidence supports an early human-mediated translocation of S. celebensis to Flores and Timor and two later, separate human-mediated dispersals of domestic pig through islands of SE Asia into Oceania. In addition to Flores and Timor, S. celebensis is also thought to occur in its domesticated form on Halmahera, Lendu, Roti, and Savur Is, and even on Simeulue and Nias Is to the W of Sumatra and far from its island of origin, Sulawesi. In the Moluccas, and possibly elsewhere in this region, introduced S. celebensis are thought to have hybridized with other introduced pigs of S. scrofa derivation, and apparent hybrids between these species are now reported to survive on a number of islands, including Salawatti, Great Kei, Dobu, Seram, Ambon, Bacan, Ternate, Morotai, and New Guinea.

A rodent anchored hybrid enrichment probe set for a range of phylogenetic utility – from order to species
<p>Rodents are the largest order of mammals and contain several model organisms important to scientific research in a variety of fields, yet no large set of genomic markers have been designed for this group to date, hindering evolutionary studies into relationships of the group as a whole. Here we present a genomic probe set designed and optimized for rodents with a protocol easy to replicate with little laboratory investment. This design utilizes an anchored hybrid enrichment approach specifically targeting rodents to generate longer loci with a higher mutation rate than existing vertebrate probes to provide utility at various taxonomic levels. Using a test set of rodents from all five suborders we successfully obtained alignments for 416 of the 418 target loci with an average of 1,379 base pairs per locus and a total alignment of more than half a million base pairs. This genomic dataset performed well in all phylogenetic analyses, especially in recent phylogenetic splits, with ample parsimoniously-informative sites within genera and even within species, showing more than four times as many single nucleotide polymorphisms per locus than a recent vertebrate ultra-conserved elements study. Additional support is provided in resolving basal clades in Rodentia. By providing this probe design, we hope that more labs can easily generate data for answering questions in rodents from species delimitation to understanding relationships among families in rapid radiations.</p>
