416 Liii. CRASSULACEJ;. (C. B. Clarke.) \_Kalanchoe. 



K. teretifoUa, Wall, does not appear separable from this var. K. acutiflora, Haw. 

 ■ in Andr. Bot. Bepos. t. 560 ; Miq. Fl. Ind. Bat. i. pt. i. 728, probably is not an Indian 

 form ; it has white flowers. 



6. COTYXiEDON, Ztnn. 



Herbs, branching or scapigerous. Leaves opposite or alternate, fleshy. 

 Flowers in spicate racemes or cymose. Calyx 5-j»^te. Corolla S-fid to the 

 base (or in non-Indian species less deeply). Stamens 10 or 5, inserted on th« 

 coroUa. Hypogynous scales oblong or quadrate. Carpels 5, free, attenuated into 

 filiform styles ; ovules very numerous. Fruit of 5 many-seeded follicles. — ^Dis- 

 TKTB. Species 60 ; in Eastern Asia, Western and Southern Europe and the whole 

 of A&ica; also in Mexico. 



The genus as it now stands includes such species as are excluded &om CrassiUa 

 by their alternate leares, and from Sedum by their spicate racemes or by having only 

 5 stamens. 



* Stem simple, leaves alternate, spike elongate dense, stamens 10. 



1. C. splnosa, Linn. Sp. PI. i. 615 ; radical leaves rosulate spathulate 

 terminated by a spine, cauUne oblong-lanceolate flat, pedicels l-flowered, 

 corolla yeUow-white twice exceeding the calyx. Umbilicus spinosus, DC. 

 Pradr. iii. 400 ; Ledeb. Fl. Boss. ii. 174. U. spinosus and U. fimbriatus, Turcz. 

 Fl. BaikalnBahur, i. 432. Sedum spinosum. Thumb. Fl. Jap. 186. 



West Tibet; Falconer ^o. 482. Baxtistan, alt. 10,000-11,000 ft., C. B. Clarie. 



Height 6-15 in. Leaves 1-1^ in. long. Pedicel i in. long, shorter than its 

 oblong acute brict. Sepals ovate, very acute, greatly exceeding the tube of the 

 coroUa. 



** Stems several, leaves attemate, cymes small, stamens 5. 



2. C. Oreades, C. B. Clarke ; annual, glabrous, stems branching &om 

 the base, branches ascending leafy, leaves on the sterile branches \ in. long, ro- 

 sulate narrow lanceolate aristate, flowers at the summit of the branches 3-1 

 nodding white. Umbilicus Oreades, Dene, in Jacq. Voy. Bot. 62 (U. luteus, 

 Ic. t. 73, except that the stamens are not ten) ; H. f. ^ T. in Joum. Linn. 

 Soc. ii. 91. 



Alpine Western Himalaya ; Kaskhib ; Pir Punjal, Jacguemont ; Marbul Pass, 

 C. B. Clarke. Gubwhal, Falconer. Kumaon, alt. 14,000 ft. ; SMl9ng, Strachey ^ 

 Winterbottom. 



Stems 2-4 in. long, several, curved. Stem-leaves like the rosulate leaves but 

 rather smaller. Sepals ^ in. long, oblong, acute. Petals a little exceeding the sepals, 

 united at their base only. Seeds ellipsoid, microscopically covered with tubercles. — 

 This spesies has the habit altogether of Sedum, but it cannot be put there because 

 it has only 5 stamens; neither can it be put in Crassula because Crassula has always 

 opposite leaves. Therefore it is put in Cotyledon ; though in Cotyledon the eoroUa 

 should be tubular, the tube at least equalling the calyx. Similar remarks apply to 

 the nest species. 



3. C. spatlralata, C. B. Clarke ; glabrous, stolon leaves rosulate ^ in, 

 long petioled spathulate, cauline linear-oblong, flowers corymbose shortly 

 pediceUed, sepals ^-f in. long oblong acute nearly equalling the corolla and 

 many times exceeding its tube. Umbilicus spathulatus, £■./. i^ T. in Joum. 

 Linn. Soc. ii. 92.
