442 LXXXV. ASCLEPIADEX (BROWN). [ Ceropegia. 
Except in habit there is no technival character whereby this plant differs from 
the genus Brachystelma. 
6. C. ringens, A. Rich. Tent. Fl. Abyss, ii. 48. Rootstock a 
globose tuber. Stem twining, slender, pubescent, herbaceous. Leaves 
very variable, ovate-lanceolate, acute, emarginate-cordate or rarely 
rounded or gradually attenuate at the base, pilose-pubescent on both 
sides. Umbels subsessile, several-flowered ; pedicels hairy. Sepals. 
lanceolate (“very narrow, linear,” in note), acute, hairy. Corolla 
curved ; tube 4 times as long as the calyx, inflated at its base, shortly 
pilose ; limb oblique; lobes free, lanceolate-linear, obtuse at the apex, 
ciliolate.— Walp. Ann. iii. 67.

I have not seen this species, but the type in A. Richard’s Herbarium has been 
examined and a drawing of a flower made for me by Mr. I. H. Burkil], from whom I 
learn that the plant is like an entire-leaved specimen of C. sinuata, Decue., except that. 
the young leaves are more hairy and the corolla-lobes shorter, Mr. Burkill’s drawing 
of the flower (drawn to scale in its dried state) represents the corolla to be exactly 
as in C. sinuata, with the tube slightly curved, of nearly equal diameter throughout, 
63 lin. long and 2 lin. in diam., and the lobes 23 lin. long. C. convrolvuloides, 
A. Rich., has been mistaken for this species by other authors. 
7. ©. sinuata, Decne. ex A. Rich. Tent. Fl. Abyss. ii. 47. Stem 
twining, more or less pubescent. Leaves herbaceous ; petiole 4-2 in. 
long; blade 1-2} in. long, 4-14 in. broad, lanceolate to deltvid-ovate or 
cordate, acute or acuminate, rounded or cordate at the base, coarsely 
and irregularly toothed or sinuate on the basal part or entire, sparsely 
pubescent on both sides, ciliolate. Umbels sessile or with peduncles up 
to 2 lin. long, 5-7-flowered, all parts except the corolla covered with a 
Spreading pubescence; bracts 1-2 lin. long, subulate ; pedicels 6-7 lin. 
long. Sepals 3-3} lin. long, 2 lin. broad, lanceolate-subulate. Corolla- 
tube 1 in. long, curved above the obliquely ellipsoid-inflated base, which 
is } in. in diam., cylindric up to the mouth above, about 2 lin. in diam., 
glabrous outside and inside; lobes free and spreading, 4 in. long, linear 
from a deltoid base, acute, replicate, blackish, sparsely pubescent on the 
back, glabrous on the face. Outer coronal-lobes arising } lin. above the 
base of the staminal-column, 4 lin. long, spreading, rectangular, dilated 
at the base, truncate at the apex, glabrous; inner coronal-lobes 1 jin. 
long, connivent-erect, linear, obtuse, minutely papillate on the apical 
part.—Walp. Ann. iii. 67; Vatke in Linnea, xl. 218; K. Schum. in

Richard describes C. sinuata, as follows: “Rootstock a globose tuber. Stem 
sk nder, twining, pubescent. Leaves petiolate, oblong, acute, obtuse at the base, with 
the margin unequally sinuate, slightly hairy, especially beneath. Flowers outside: 
the axils, 2-3 together, pedicellate; pedicels slender, shortly hairy. Sepals linear,
