X. OBESIA (obesus, fat; flowers). 
Stapélia species of authors. 
Lin. syst. — Pentándria, Digýnia. All as in Stapélia; but 
the exterior corona is 5-lobed, therefore there are no ligule ; 
the orb or ring is also wanting. Leaflets of inner corona bi- 
partite, yellow, small, thick, and truncate, thickest at the apex ; 
outer branch spreading; inner branch semicylindrical, closely 
incurved above the table of the style.—Glaucescent plants with 
the habit of Stapelia. Joints of branches short, almost oblong, 
very thick, obsoletely tetragonal, radicant: with small, hori- 
zontal teeth. Flowers small, usually twin. 
1 O. cemina‘ta (Haw. syn. p. 42.) joints of branches pro- 
liferous, creeping, suboval, obscurely tetragonal, floriferous at 
top; flowers usually twin; outer corona 5-lobed ; margins of 
segments of corolla revolute. h. S. Native of the Cape of 
Good Hope.  Stapélia geminàta, Mass. stap. p. 18. t. 25.

ceolate, acuminated, rather hairy inside, when examined by a lens, 
ex Mass. Lobes of outer corona tridentate.

2 O. pecdra (Haw. syn. p. 43.) joints of branches oblong, 
obsoletely tetragonal, floriferous at base; flowers twin ; outer 
corona 5-lobed ; segments of corolla scabrous from dots above, 
lanceolate, acuminated, with revolute edges. 5. S. Native of 
the Cape of Good Hope. Stapélia decóra, Mass. stap. p. 19. 
t. 26. Corolla yellow, beset with dark purple, elevated dots. 
It differs from O. geminata in the joints of the branches being 
smaller, in the teeth being stronger, and in the flowers being 
rather larger, and scabrous from dots.

XI. DUVA'LIA (named after H. A. Duval, of Paris ; author 
of Enumeratio Plantarum Succulentarum in Horto Alenconio). 
Haw. syn. p. 44.—Stapélia species of authors. 
Lin. syst. — Pentándria, Digynia. All as in Stapélia; but 
the segments of the corolla are more or less bent to one side ; 
the orb is elevated; the lobes of the outer corona are entire, 
bifid, or emarginate at apex ; the segments of the inner corona 
are minute, hollow, resembling a bird's head, and incurvedly ad- 
pressed to the angles of the style ; the table of the style is round, 
a little repand, with 5 angular depressions.—Habit of Stapélia. 
Branches short, proliferous, almost as in Piaránthus, often shorter 
and more glomerate, and throwing out numerous roots, usually 
glaucescent.
