DOUBTFUL SPECIES. 



C. HEYNEANA, Eoem. $ Sch. Syst. vi. 101 ; Dene, in DC. Prodr. viii. 549. Periploca 

 reticulata, Roth, mss. May be C. Callialata. 



C. PEDTINCULATUM, Thunb. Obs. in Cynanch. 5 ; Dene, in DC. Prodr. viii. 548, 

 from Ceylon is undeterminable. 



C. TOMENTOSUM, Lamk., is probably Tylopkora asthmatica, according to Wight 

 (Contrib. 51, in note). 



27. SARCOSTEXIXIKA, Br. 



Trailing leafless jointed shrubs with pendulous branches. Cymes terminal 

 or at the nodes, umbellitorm ; 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. DISTRIB. 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.
