FIGURE 3. A. A dense stand of Kalanchoe beharensis. B. Close-up of the stem of K. beharensis. C. Although variable, the leaf blades of most variants of K. beharensis are somewhat elongated-triangular, deltoid to peltate, and irregularly folded lengthwise and also in width. D. A severed leaf of K. beharensis that developed numerous small plantlets at the proximal end of the petiole. E. In winter, K. beharensis bears a much-branched, laterally-borne inflorescence. F. The corolla lobes K. beharensis are more or less recurved—sometimes strongly so—and greenish pink to pale yellow to yellowish green with prominent longitudinal, reddish purple stripes. The basally fused, elongatedtriangular sepals obscure most of the corolla tube. All photographs: Gideon F. Smith.

FIGURE 1 in Publication of Kalanchoe sect. Trichanthae (Crassulaceae subfam. Kalanchooideae), a new status for K. [infragen. unranked] Trichanthae of Alwin Berger (1930), in K. subg. Calophygia (2006 as amended in 2023)

FIGURE 1. Kalanchoe synsepala, one of the species included in K. sect. Trichanthae. A. Plants are low-growing, pseudo-rosulate, seldom-branched perennials. Leaves are distinctly succulent and their margins are variously adorned with shallow or deep indentations. Note the scattered brown spots on the leaf surface. B. It is the only known stoloniferous kalanchoe. C. The peduncle is slender and at first held erectly. Note the shark tooth-like, lateral outgrowths. D. The calyx is substantially fused into a globule-like tube. E. Flowers are distinctly or obscurely finely hairy. The adaxial surface of the corolla lobes of this light pinkish-flowered variant is longitudinally distinctly adorned with darker, purplish veins. F. The adaxial corolla surface of this variant is nearly pure white, with only a slight light pink-infusion. All photographs: Gideon F. Smith.

FIGURE 2. Representatives of Kalanchoe subg. Calophygia Desc. emend. Gideon F.Sm. use a diverse range of vegetative and sexual reproductive strategies. Some of the vegetative strategies are shown here. A. Rhizomatous sprouts developing in the proximity of a specimen of K. beharensis that has not yet reached reproductive maturity. B. Plantlets developing from the proximal end of a turgid, severed leaf of K. rhombopilosa, type of K. sect. Rhombopilosae. The leaves of this species are easily shed. C. Plantlets developing on the inflorescence of K. bracteata. D. A cluster of plantlets sprouting at the proximal end of the petiole of a severed leaf of the non-tomentose variant of K. beharensis, which is generally known as "Kalanchoe beharensis var. subnuda" Jacobsen (1970: 250), nom. inval. (Turland et al. 2018: Art. 39.1). Note that the plantlets are at first tomentose, but the tomentum is lost as plants mature. All photographs taken by Gideon F. Smith.

FIGURE 2. This N.E. Brown s.n. specimen of Kalanchoe ×kewensis, which was mounted as two preparations, is identifiable as: A. K barcode K000838472 [image available at http://specimens.kew.org/herbarium/K000838472] and as B. K barcode K000838473 [image available at and http://specimens.kew.org/herbarium/K000838473]. This two-preparation specimen is here designated as the lectotype of the name K. ×kewensis Brown (1902 [14 June]: 387). The metadata associated with the specimen are: "Kalanchoe kewensis[,] N.E.Br.! in Gard. ChrOn. 1902[,] V. 31, p. 387 Type SpecImen! a hybrId between K. BentII ♁ & K. flammea ♀ Kew GardenS JUne 1902 N.E. BrOwn". The description that appeared in Anonymous (1902 [12 July]: 26–27) was pasted onto the lower right hand corner of the N.E. Brown s.n. preparation with barcode K000838473. In addition, this sheet carries the handwritten statement, in pencil, "Sheet 2".

FIGURE 1 in The taxonomy and nomenclature of Kalanchoe ×kewensis [K. bentii × K. glaucescens] (Crassulaceae subfam. Kalanchooideae), a nothospecies produced at the Royal Botanic Gardens, Kew, in the early 1900s

FIGURE 1. Kalanchoe ×kewensis [Arabian material of K. bentii, i.e., K. bentii subsp. bentii, × K. glaucescens]. A. Plants are usually single-stemmed and can (rarely) reach a height of 1.2 m when in flower. B. Leaves are cylindrical-elongated to lanceolate, taper to both ends, and, at maturity, ± halfway up, have prominent, curved, harpoon-like, lateral outgrowths that point towards the leaf tips. C. In some specimens branching may take place from the base. D. Close-up of buds and a flower at anthesis. The sepals are flared away from the tube. The ovate to slightly obovate corolla lobes are uniformly bright vibrant pink, but could sometimes be adorned with narrow, white margins. E. Flowers often develop abnormally, for example with all four corolla lobes concentrated to one side of the apex of the corolla tube, or they deviate by being pentamerous, rather than tetramerous, the latter condition being prevalent virtually throughout in Kalanchoe. Such deviations in floral morphology are often found in hybrid kalanchoes. F. A plantlet that developed just below the desiccated inflorescence. G. The follicles are tightly enveloped in the dry, persistent, creamy white to straw-coloured remains of the corolla and the reddish brown remains of calyx. All photographs: Gideon F. Smith.
