FIGURE 1 in Kalanchoe deliae (K. [subg. Kalanchoe] sect. Raveta; Crassulaceae subfam. Kalanchooideae), a new species from the Barberton Centre of Endemism in northeastern southern Africa
FIGURE 1. Kalanchoe deliae from central-east Mpumalanga, South Africa. A. Lower, leafy section of a stem. The opposite-decussate, amplexicaul, erect to slightly erectly spreading leaves are infused with rusty brown along the leaf margins only. B. Leaves are light green, obovate to broadly elliptic, sometimes very slightly curved up along margins and have a ± cuneate base that is sometimes very slightly auriculate. C. Roots are fibrous to slightly thickened and the stems are a uniform light green colour. D. The erect to leaning, club-shaped inflorescences are apically dense- and many-flowered. E. The flowering portion of the inflorescences is 110–130(–150) mm long and the branches are borne oppositely, with the branches slanted away from the main flowering stem at an angle of 10–15°. The internodes are very short, so yielding dense-clustered inflorescences. F. All plant parts are densely white-wax-covered. The adaxial surface of the corolla lobes are light green and light rusty brownish-infused towards the tips, with the margins usually paler. All photographs: Gideon F. Smith.
FIGURE 2. Kalanchoe luciae. A in Kalanchoe deliae (K. [subg. Kalanchoe] sect. Raveta; Crassulaceae subfam. Kalanchooideae), a new species from the Barberton Centre of Endemism in northeastern southern Africa
FIGURE 2. Kalanchoe luciae. A. Plant in flower. The inflorescence has a dense white-wax covering. B. Pseudo-rosette showing intensely red-infused leaves. C. Terminal portion of an inflorescence. The internodes are long, so yielding inflorescences with ± regularly spaced flower clusters. D. The adaxial corolla lobe surface varies from white, as here, to pale yellowish. In orientation the corolla lobes generally vary from strongly reflexed to completely flattened against the corolla tube, as here. Note how the corolla tubes bulge in the centre. All photographs: Gideon F. Smith.
Elephant population survey counts across southern Africa protected areas
<p><span>The influence of protected areas on the growth of African savannah elephant populations is inadequately known. Across southern Africa, elephant numbers grew at 0.16% annually for the past quarter century. Locally, much depends on metapopulation dynamics — the size and connections of individual populations. Population numbers in large, connected and strictly protected areas typically increased, were less variable from year to year, and suffered less from poaching. Conversely, populations in buffer areas that are less protected but still connected </span>have more variation in growth from year to year<span>. Buffer areas also differed more in their growth rates, likely due to more threats and dispersal opportunities in the face of such dangers. Isolated populations showed consistently high growth due to a lack of emigration. This suggests that "fortress" conservation generally maintains high growth, while anthropogenic-driven source-sink dynamics within connected conservation clusters drive stability in core areas and variability in buffers. </span></p>

Revised taxonomy of the Arctotis Annual Clade (Arctotideae, Asteraceae) from Southern Africa: integration of molecular phylogenetic and morphological evidence
<p>Previous phylogenetic analysis of ITS nrDNA sequence data for Arctotidinae species resolved a highly supported clade containing all but one of the showy annual <i>Arctotis </i>species (informally designated the '<i>Arctotis</i> Annual Clade')<i>.</i> In the present study, phylogenetic relationships in the <i>Arctotis </i>Annual<i> </i>Clade were investigated by Bayesian inference and maximum parsimony analyses of cpDNA (<i>trnT-trnL-trnF</i> and <i>trnH-psbA</i>) and nrDNA (ITS) sequence data. The cpDNA and nrDNA phylogenies were notably incongruent. <i>Arctotis venusta </i>and a putative unnamed species<i> </i>('sp. B') were highly supported as monophyletic by both datasets. The monophyly of <i>A. leiocarpa </i>was strongly supported by the ITS dataset, whereas the remaining accessions formed a poorly resolved complex (the '<i>A. fastuosa </i>complex'). Within the <i>A. fastuosa </i>complex, <i>A. hirsuta </i>was monophyletic with high support in the ITS phylogeny. A statistical parsimony-derived cpDNA haplotype network resolved five broad groups of haplotypes and showed no consistent geographical structure, but species-specific haplotype lineages<i> </i>for<i> A. venusta </i>and sp. B were resolved. <i>Arctotis fastuosa </i>accessions were distributed among four haplotype groups. Incongruence between the datasets and poor resolution within the <i>A. fastuosa </i>complex may reflect reticulate evolution, ancestral polymorphism, and incomplete lineage sorting, in tandem with the low information content of the datasets. The greatest phenotypic diversification in the clade is in cypsela morphology. Comparison of cypsela morphology with the phylogenies suggests a general trend for reduction in the sizes of the cypsela, abaxial wings, and pappus scales, and loss of pubescence during diversification. A revised taxonomy, integrating currently available evidence, accompanied by full descriptive accounts and a key to the taxa are presented. Eight species are recognized, including the nomenclatural novelties <span><b><i><span>Arctotis chrysantha</span></i></b></span> (sp. nov.) and <span><b><i><span>Arctotis namibiensis</span></i></b></span><i> </i>(sp. nov.). The names <i>Arctotis karasmontana</i>, <i>Venidium fugax</i>, and <i>Venidium macrocephalum</i> are lectotypified.</p>
