Names
Adromischus hemisphaericus [family CRASSULACEAE]
Common names
Cotyledon hemisphaerica L., Sp. PI. edn 1, 429 (1753); DC, PI. Hist. Succ. t. 87 (1802); Prodr. 3: 398 (1828); Eckl. & Zeyh., Enum. 307 (1837), pro parte; Harv. in F.C. 2: 376 (1862), pro parte; Schonl. in Rec. Albany Mus. 3: 152 (1915), pro parte excl. C. triflora. C. crassifolia Salisb., Prodr. 307 (1796). Type: un­known. C. rotundifolia Haw. in Phil. Mag. 1827: 273 (1827); Schonl. & Bak. f. in J. Bot., Lond. 40: 91, t. 435 (1902); Dyer in Curtis's bot. Mag. 157, t. 9368 (1934). Adromischus rotundifolius (Haw.) C.A. Sm. in Botha-lia 3: 627 (1939); V. Poelln. in Kakteenkunde 1940: 17, one fig. (1940). Type: sine loc., Haworth s.n. (OXF, holo.!).
Information
Perennials with suberect or decumbent branches up to 0,25 m long, usually much branched, with fibrous roots. Leaves oblan-ceolate to obovate, rarely orbicular, (10-) 15-25(-45) x 10-20(-30) mm, usually abruptly cuneate, obtuse or rounded, dorsi-ventrally compressed and often somewhat convex on both surfaces, often with indis­tinct horny margin in upper half, usually grey-green with or without darker spots and with flaking wax. Inflorescence a spike-like thyrse with l(-2)-flowered cymes, 0,15-0,25 m long, green; pedicels (l-)2-3 mm long. Buds terete, abruptly tapering towards apex, spreading. Calyx 1,5-2,5 mm long, greyish green. Corolla with cylindrical tube 9-13 mm long, green more or less tinged brown; lobes broadly triangular, 2-2,5 mm long, cuspidate, rough and rarely with a few club-shaped trichomes in throat, white or more or less tinged pink and darker around throat and on mucro. Anthers exserted. Squamae transversely oblong to square, 0,8-1,1 x 1-1,2 mm, scarcely emarginate, usually broadest at or below middle.
Habitat
Very few records of populations of this species from east of the Hottentotsholland Mountains are available so that it has not been possible to evaluate whether this more robust eastern form should be given separate rank (cf. Tolken, 1978). The robust straight stems distinguish A. hemisphaericus from A. roaneanus (no. 3), but too little material is available to determine whether the latter is just a form of the former.
Use
4. Adromischus hemisphaericus (L.) Lem., Jard. Fleur. 2, Misc. 60 (1852); C.A. Sm. in Bothalia 3: 625 (1939); V. Poelln. in Reprium nov. Spec. Regni veg. 48: 105 (1940); Tolken in Bothalia 12: 385 (1978). Type: Dill., Hort. Eltham. t. 95, fig. Ill (1732).
Range
Localized populations on the Cape Peninsula and occasionally in the Hottentotsholland Mountains and eastwards from near Caledon to Worcester. Flowering period: November, December.
