Tuberous-rooted Ceropegia. Fl. April, Sept. Clt. 1821. 

 PI. tw. 



22 C. LOUREIIUI ; herbaceous, glabrous, procumbent ; leaves 

 ovate-lanceolate, with revolute edges ; umbels pendulous ; 

 corolla with a large, globose base, and a small, 5-cleft limb. 

 1f-. f ^. G. Native of Cochinchina, among bushes. Ceropegia 

 candelabrum, Lour. coch. 114. Flowers white. Stigma sessile, 

 bifid. Follicles slender. 



Lourciro's Ceropegia. PI. twining. 



23 C. OBTU'SA (Lour. coch. 1 14.) twining, glabrous ; leaves 

 oblong, obtuse; peduncles shorter than the leaves. 1{. r *. S. 

 Native of Cochinchina, in the suburbs of Huaca. Flowers paler 

 than those of C. tuberbsum, from which it differs more in the 

 shape of the leaves than in the flowers ; the follicles are also 

 slenderer. 



Blunt-leaved Ceropegia. PI. tw. 



+ Species hardly knotvn. 



24 C. CANDELABRUM (Lin. spec. p. 309.). It.^.S. Na- 

 tive of Malabar. Rheed. mal. 9. t. 16. Leaves ovate, mucro- 

 nate. Flowers erect, reddish or brownish purple ; with villous 

 segments. This species has been taken up by Linnaeus from 

 Rheede's figure. It seems to be nearly allied to C. tuberbsa, 

 but has a very different habit. The C. candelabrum of most 

 modern authors is undoubtedly C. tuberbsa. 



Chandelier Ceropegia. PI. tw. 



25 C. DICHOTOMA (Haw. syn. p. 13.) fleshy; stem erect, 

 dichotomous, articulated, terete ; leaves linear, acute, horizontal ; 

 having the veins and midrib white above. I? . S. Native of 

 the East Indies ? Flowers ? Leaves \\ inch long. 



Z)/'cAotoW!OiM-stemmed Ceropegia. Shrub 1 foot. 



26 C. ? CAMPANULA X TA ; root round, depressed : leaves linear ; 

 corolla tubularly campanulate, 4-cleft ; calyx small, 4-5- 

 toothed. If. . S. Native of the Gold Coast, at Accra, among 

 grass. Corolla dark purplish brown. Perhaps a new genus. 

 There is also another species growing along with this, which 

 differs from the first in the root being fusiform. The roots of 

 both are eatable. Stem 1-2-flowered in both. Flowers ter- 

 minal.

 formed, adpressed. fj *"* S. Native country unknown. 



Leafless Ceropegia. Shrub tw. 



28 C. ? NITIDA (Poir. diet, suppl. 2. p. 178.) leaves lanceo- 

 late, bluntish, sliining above; umbels on short peduncles, fy . S. 

 Native of St. Domingo. Stem woody. Branches slender, elon- 

 gated. Leaves subovate, sometimes elliptic, attenuated at the 

 base, and sometimes acute at the apex, 1-2 inches long, and | 

 broad. 



Shining-leaved Ceropegia. Shrub tw. 



29 C.? SINUA'TA (Poir. diet, suppl. 2. p. 179.) leaves narrow- 

 lanceolate, sinuated, acute at both ends ; umbels 4-6-flowered, 

 much shorter than the leaves. 2f. ^\ G. Native of the Cape 

 of Good Hope. Burm. afr. p. 36. t. 15. Root a fascicle of 

 fusiform simple tubers. Corolla tubular, pale red. There is only 

 one follicle comes to perfection from each flower ; it is pendulous 

 and long-acuminated. Seeds numerous, oblong, brown. Said 

 to differ from Microlbma sagitlata in the leaves being longer 

 and not sagittate at the base.

 nivent. y. . ^. S. Native of Cochinchina, in hedges. Flowers 

 greenish yellow, in large, hemispherical, axillary umbels. 



Calycine segments small, ovate, acute. Perhaps the same as 

 Cyndnchum cordifblium, Retz. fasc. 2. p. 15. no. 37. 



Cori/ate-leaved Ceropegia. PI. tw. 



31 C. STAPELLEFORMIS (Haw. in phil. mag. feb. 1827. p. 

 121.) branches, prostrate, fleshy, thong-formed, lurid, terete, 

 nearly leafless, simple, clouded with brown. (? . S. Native of 

 the Cape of Good Hope. This species has the habit of O'rbea. 

 Branches rough from tubercles. Leaves very minute, ternate, 

 almost invisible, and as if they were adnate to the stem, cordate, 

 cuspidate. Flowers sessile, rising from the axils of the leaves. 



StapeHa-formed Ceropegia. Fl. July. Clt. 1824. PI. proc. 



Cult. A mixture of peat, sand, and vegetable mould is the 

 best soil for these plants ; cuttings of them root readily in sand, 

 if placed in heat, without any hand-glass over them. They 

 should have little or no water, when in a dormant state, parti- 

 cularly the bulbous-rooted kinds.

 masses erect, fixed by the base, having one of the margins 

 cartilaginous and pellucid. Stigma mutic. Follicles sub-cylin- 

 drical, smooth. Seeds comose. Succulent plants with the

 peduncles being 2-3-flowered.
