ASCLEPIADEjE. IV. STAPELIA. 



3. Lignite, or segments of the outer corona, rhomb-oblong or 

 cuneated. Leaflets of inner corona simple, subulate, undulated. 

 Stems glabrous, with 4 equal sides, but much more slender than 

 those of the former section. This is probably the best marked 

 section of the genus ; nevertheless the species agree in habit, 

 and teeth of branches, with the last. 



20 S. CONCINNA (Mass, stap. p. 15. t. 18.) branches glabrous, 

 floriferous at the base, with erect teeth ; segments of corolla 

 ovate-lanceolate, acute, ciliated ; bottom of corolla villous, ex 

 Haw. Tj . S. Native of the Cape of Good Hope, in Karro. 

 Heyne, term. bot. t. 16. f. 8. Flowers about the size of those 

 of Anemone nemorosa, flat, grey, with transverse, undulated, 

 fuscous stripes, and white bristles ; and a brown bottom. Pe- 

 dicels purplish, usually twin. Segments of outer corona emar- 

 ginate.

21 S. GLANDULIFERA (Jacq. stap. t. 46.) branches glabrous, 

 floriferous in the middle ; corolla very villous ; segments ovate, 

 acuminated ; villi sub-spatulate, white ; ligulae rhomb-oblong, 

 quite entire, horny, obtuse. \ . S. Native of the Cape of 

 Good Hope. Pedicels twin or tern, hairy, filiform. Corolla 

 small, yellowish, having the bottom and numerous concentric, 

 transverse, broken stripes, rufous. Ligulae yellowish brown. 

 Stamens bay- coloured.

22 S. FLAVICOMA'TA (Haw. suppl. pi. succ. p. 8.; stems nume- 

 rous, quadrangular, slender ; angles equal, downy, teeth leaf- 

 formed, turnid, and contiguous. ^ . S. Native of the Cape of 

 Good Hope. Very nearly allied to S. glandulifera ; but the 

 branches are thicker, more numerous, shorter, with the teeth 

 larger, more leaf-formed, and more close together. 



Yellow-haired Stapelia. Fl. July. Clt. 1810. Shrub \ foot. 



23 S. HispiDULA (Hornem. hort. hafn. p. 251.) segments of 

 corolla acuminated, wrinkled transversely, hispid from clavate 

 hairs, replicate and naked at apex ; segments of outer corona or 

 ligulse entire, acute : of the inner subulate, connivent ; pedicels 

 aggregate, almost radical, much longer than the corollas. ^ . S. 

 Native of the Cape of Good Hope. This species differs from 

 H. concinna, Mass, in the pedicels being very long, and almost 

 radical, in the segments of the corolla not being ciliated, and in 

 the segments of the exterior corona being undivided.

24 S. GLANDULIFIORA (Mass. stap. p. 16. t. 19.) branches 

 glabrous, with erect, acute teeth, floriferous at the base ; pedun- 

 cles twin or tern ; corolla clothed with white, clavate, seta- 

 ceous glands : segments ovate-lanceolate, acute, spreading. Pj . 

 S. Native of the Cape of Good Hope, among bushes, about 

 North Olifant's river. Smith, exot. bot. t. 19. Jacq. stap. 

 t. 40. Branches spreading. Corolla size of those S. con- 

 cinna, sulphur-coloured. Corona orange and black, ex Willd. 

 Pedicels purplish. Corolla about the size of those of Anemone 

 nemorosa, shorter than the calyx, spotted with deep red dots ; 

 and the bottom deep brown, ex Mass.

25 S. ACUMINA'TA (Mass. stap. p. 15. t. 17.) branches gla- 

 brous,, floriferous in the middle ; pedicels glabrous, twin or tern, 

 shorter than the corolla ; segments of corolla ovate, cuspidately 

 acuminated, ciliated on the edges ; the rest of the corolla gla- 

 brous. Jj . S. Native of the Cape of Good Hope, in Namaqua 

 Land. Corollas a little larger than those of H. rufa ; segments 

 green, variegated with dark purple stripes, transversely undu- 

 lated, tipped with dark purple. Segments of calyx oval, 

 acute.

4. Anmnalce. Anomalous species, without the characters of 

 the preceding sections, and which mill probably constitute 

 new genera, but the characters are not sufficiently known as 

 to establish these genera. 



" Obtuse - dentatee. Angles of branches obtuse, having the 

 teeth almost obliterated, or very blunt. 



26 S. APE'RTA (Mass. stap. p. 23. t. 37.) branches numerous, 

 tetragonal, sub-tridentate at the apex, glaucescent ; corolla flat, 

 segments ovate, obtuse, 5-nerved, wrinkled, with glalirous edges, 

 tj . S. Native of the Cape of Good Hope, in Namaqua Land, 

 near Kok Fountain. Pedicels twice longer than the branches, 

 usually solitary. Corolla obscure, purple, with dashes of a 

 more obscure colour ; bottom circular, greyish, dotted with 

 black. Perhaps a species of Caruncularia. 



Open-flowered Stapelia. Fl. July, Aug. Clt. 1795. Shrub 

 1 foot. 



27 S. RAMOSA (Mass. stap. p. 21. t. 32.) branches numerous, 

 erect, tetragonal, glaucescent ; flowers aggregate, almost sessile ; 

 segments of corolla lanceolate, acute, with revolute edges. ^ . 

 S. Native of the Cape of Good Hope, in Karro, beyond Platte 

 Kloof. Pedicels very short, rising from the upper part of 

 the branches, without the teeth. Angles of branches sinuated. 

 Corollas size of those of H. pruinosa, dark purple, with a cir- 

 cular white bottom. Perhaps a species of Piardnthus. 



Branched Stapelia. Fl. Ju. July. Clt. 1795. Shrub 1 foot. 



* * Branches terete, tubercular ; having a hair or spine rising 

 from each tubercle. 



28 S. PILIFERA (Lin. suppl. 171. Thunb. prod. 1. p. 46. fl. 

 cap. 2. p. 165.) branches numerous, terete, furrowed ; tubercles 

 furnished each with a bristle ; flowers sessile, solitary ; corolla 

 campanulate, with ovate, acuminated segments ; segments of 

 corona bifid. ^ . S. Native of the Cape of Good Hope, on 

 very arid hills, under bushes, in Karro, beneath Roggeweld, 

 Masson ; beyond Hartequas Kloof, Thunb. Flowers small, 

 purple, at the tops of the branches, Lin. Corolla size of that of 

 S. drida, dark purple, with a red circle in the middle, ex Mass. 

 Corolla smooth outside, but muricated by elevated callosities 

 inside, ex Thunb. Perhaps this will form a new genus. 



Piliferous Stapelia. Fl. Ju. Aug. Clt. 1790. Shrub. 



29 S. GoRDbta (Mass. stap. p. 24. t. 40.) branches terete ; 

 tubercles terminating each in a spine ; pedicels solitary, at the 

 tops of the branches ; corolla large, 5-toothed ; teeth or seg- 

 ments broad, roundish, short-acuminated ; exterior corona 5- 

 toothed. fj . S. Native of the Cape of Good Hope, in Groot- 

 Namaqua Land, towards the orange river. Corollas among the 

 largest of the genus, almost 3 inches in diameter, repandly 5- 

 toothed, of a brownish yellow colour, with a whitish centre ; 

 segments of the corona short, black in the middle, and white on 

 the margins. Follicles solitary, erect, long, acute. This differs 

 from all other species, in the singular form of the corolla, and in 

 the solitary follicles ; it therefore will hereafter constitute a new 

 genus, which we would propose calling Monothylaceum, from its 

 solitary follicles.

 arranged in any of the sections above. 



30 S. CORDA'TA (Hort. ex Haw. syn. p. 26. no. 27.) 1? . S. 

 Native of the Cape of Good Hope. There is nothing known 

 of this plant but the name.
