 (Ceropegief^) : —

 Erect, fleshy, with 4-angled leafless stems. Fls. 



large 23. Boucerosia. 



1. HEMIDESMUS, Br. 



Twining suffruticose herbs or slirnbs. Fls. small, greenish purple, 

 in dense stibsessile cymes. Sepals glandular within. Corolla rotate 

 with thick valvate lobes. Corona corolline, of 5 scales on the throat 

 alternate with the lobes. Filaments distinct, anther-tips connate 

 inflexed membranous, pollinia granular, 2 in each cell attached to 

 corpuscle by dilated appendages. Stigma with flat crown, 5-angled. 

 Follicles long slender, terete, divaricate or reflexed. 



1. H. indicus, Br. Anandamal, H., Beng. ; Kapri (Sambalpur). 



A slender twining shrub with an aromatic rootstock, rather distant 

 pairs of leaves, 1-4" by -S-IS", most variable in shape but always 

 apiculate, pale beneath and very freqviently with a white streak above, 

 base rounded and fe^v sec. n. The small floAvers •2"~'25" diam. are 

 clustered in the leaf-axils and are green outside but purple within. 

 Follicles spreading in fruit 4-5" by 2" diam. 



Under shade and mostly in moist localities, distributed throughout the area, 

 sometimes common ! Fl. Aug.-Sept. Fr. Oct.-Dec. Evergreen. 



Glabrous or (var. puhescen^) pubescent. Leaves linear to broadly eUiptic rarely 

 obovate or lanceolate, sec. n. 5-6 but intermediate often nearly as strong and 

 rather irregular, looping and very reticulate between. Petiole •15-"25". Cymes 

 with numerous small ovate acute bracts on branches and pedicels. Sepals 

 spreading and calyx sometimes '25" diam. in fruit. Petals rather fleshy and 

 coronal scales usually mere small fleshy knobs. The corpuscle is prominent as a 

 small white tongue to which the two pairs of pollinia ai-e attached ; they are dragged 

 out of the anther by the growth of the filaments and ultimately lie naked. 



The rootstocks which are about '2- 6" diam. with brown skins but white within 

 are easily distinguished from those of Ichnocarpus by their sweet smell. They are 

 in high repute for fever and skin diseases.
