leaves: the lateral lobes united by pairs into 5 ligulate forked 
leaflets, alternating with the primary lobes and with the stamens. 
1 C. apscE/wpnENs (R. Br. 1. c.) branches slender, ascending, 
bearing each a solitary flower at top; segments of corolla re- 
flexed at the edges, acuminated, glabrous. 5. S. Native of 
Coromandel. Stapélia adscéndens, Roxb. cor. l. p. 82. t. 30. 
Corollas size of those of Periploca Greca, yellowish ; seg- 
ments tipped with violet. Stems rooting at the base. Flowers 
variegated with purple and yellow, ex Roxb., usually drooping.

2 C. ridBRià TA (Wall. pl. 
asiat. rar. 1. p. 7. t. 8.) branches 
elongated, attenuated ; flowers 
axillary, solitary, subcampanu- 
late, drooping ; segments of co- 
rolla faleate at top (f. 15. e.), 
with replicate, fringed edges. 
h. S. Native of the Burmese 
empire, on sterile sandy hills at 
Yenangeum, on the banks of the 
Irrawaddy ; and among the ruins 
of Pagamon. Stem branched 
at top. Segments of corolla 
naked in the lower part, marked 
with many transverse purple 
lines, pale yellow beneath; up- 
per part purple; upper margin 
straight and downy, fringed behind with articulated vacillating 
hairs. "Very closely allied to C. adscéndens, but that species 
differs from this in the absence of the long vacillating hairs to 
the corolla.  Stapélia subulàta, Forsk. cat. arab. p. 108. no. 
193. t. 7. is the same, or a very nearly allied species. (f. 15.)

with buffalos’ horns; in reference to the curved lobes of the 
corona). Wight and Arnott, contrib. ind. bot. p. 34. Carallüma 
species, Haw. and Wall. Stapélia species, Roxb. 
Lin. syst.  Pentándria, Digynia. Corolla subcampanulate, 
5-cleft; segments broadly triangular, with acute recesses. 
Column of fructification hardly exserted. Stamineous corona 
15-lobed; lobes disposed in a double series; the 5 inner ones 
opposite the stamens, and lying upon the anthers; the rest ex- 
terior, erect, or a little incurved at apex, adhering to the back 
of the inner ones. Anthers simple at the apex; pollen masses 
erect, tetragonal, pellucid on the one side at the margin. 
Stigma mutic. Follicles smooth, terete, attenuated at the apex. 
Seeds comose.— Fleshy, leafless, erect plants, with the habit of 
Stapélia. Branches and stems tetragonal ; with toothed angles. 
Flowers numerous, terminal, umbellate. — In Carallima the 
lateral lobes of each leaflet of the corona are separated by 
means of the middle or primary lobe, with the edge of which 
they cohere at the base: in this genus, on the contrary, the 
edges of the lateral lobes of each leaflet cohere, and their 
line of junction is also attached along the middle of the back 
of the primary lobe. In both genera the lateral lobes cohere 
by the margins with the lateral ones of the adjoining leaflet ; 
so that in Carallàma we have a corona of 10 narrow and 5 
broad segments, attached to each other by the edges only, and 
forming consequently a simple series, while, in Boucerósia the 
5 broad segments are surrounded by the 10 narrow ones, and 
a double corona is formed. Wight. and Arnott, contrib. ind.

a most successful cultivator and liberal distributor of succulent 
plants). Wight and Arnott, contrib. ind. bot. p. 34. 
Lin. syst.  Pentándria, Digynia. Corolla subcampanulate, 
5-cleft. Column of fructification hardly exserted. Stamineous 
corona 20-lobed; the 5 inner lobes lying on the anthers, the 
next 5 outside of these alternating with them, each of these 5 
furnished with 2 lateral lobes, which exceed the middle one. 
Anthers simple at top. Pollen masses erect, pellucid on the 
margin on one side.—A fleshy, leafless, erect plant; branches 
tetragonal : with toothed angles. Flowers numerous, terminal, 
subumbellate. Corolla pilose inside.

XVII. ERIOPETALUM (from ecpıov, erion, wool, and 
meradov, petalon, a petal; segments of corolla usually densely 
villous inside). Wight, contrib. ind. bot. p. 35. 
Lin. syst.  Pentándria, Digynia. Corolla subcampanulate, 
5-cleft ; segments narrow, linear: with broad recesses. Sta- 
mineous corona 15-lobed; the 5 inner lobes lying upon the 
anthers ; the 10 exterior ones erect, approximate, adhering to 
the inner series. Anthers simple at apex; pollen masses fixed 
nigh the base, erect, lying upon the stigma, pellucid on the 
margin on one side.  Follicles slender, glabrous.—Erect, 
rather branched herbs. Stems terete. Leaves minute, scale- 
formed, adpressed. Flowers small, umbellate ; umbels lateral 
or terminal, sessile. Segments of corolla longer than the tube, 
usually clothed with dense villi or wool inside, hence the generic 
name. This genus agrees in habit with Microstémma, but differs 
in the form of the corona; on the other hand it resembles 
Boucerósia in the corona, but has a widely different habit.
