DOUBTFUL SPECIES. 
C. Heyneana, Roem. § Sch. Syst. vi. 101; Dene.in DC. Prodr. viii.549. Periploca 
reticulata, Roth. mss.—May be C. Callialata. 
C. peouncutatum, Thunb. Obs. in Cynanch. 5; Dene. in DC. Prodr. viii. 548, 
from Ceylon is undeterminable. 
C. TOMENTOSUM, Lamk., is probably Tylophora asthmatica, according to Wight 
(Contrib. 51, in note). 
27. SARCOSTEMMA, Pr. 
Trailing leafless jointed shrubs with pendulous branches. Cymes terminal 
or at the nodes, umbelliform ; peduncle clavate. Flowers small. Calyx 5-fid. 
Corolla rotate, 5-fid; lobes broad, overlapping to the right. Corona cup- 
shaped, membranous, adnate to the base of the column, 10-crenate or -lobed, 
the lobes opposite the stamens bearing large fleshy processes which are adnate 
to the backs of the anthers. Column short ; anther-tip inflexed ; pollen-masses 
one in each cell, pendulous, slender, waxy. Stigma conical or shortly fusiform. 
Follicles smooth. Seeds comose.—Distrip. Species 5 or 6; Asiatic, African, 
and Australian. 
I am unable to determine the described species of this genus from dried specimens. 
There are probably differences in the fruit and seeds between the four supposed 
Indian ones, but I have no sufficient materials to verify this, and those may be 
reduced to two.
