lobeB linear with reflexed margins, anthers with membranouB margins and a 

 membranous ligule behind and below the inflexed tip, stigma broadly turbinate. 



SiKKiM HiKALAYA, alt. 5-6000 ft., Thomson. 



Stems slender. Leaves 3-6 by |-3J in., base acute or narrowly rounded ; nerves 

 oblique, very faint ; petiole stout, f-f in. Peduncle i-li in., rather slender ; flowers 

 umbeUed, pedicels twice or thrice as long as the coroUa-tube. Sepals very small, 

 broadly oblong. CoroUa-tuhe I in. ; lobes as long, spreading, thick. — A very remark- 

 able plant, resembling G. stenoloba, but differing totally in the texture of the leaves, 

 the reflexed margins of the corolla-lobes and especially in the winged anthers with a 

 membranous ligule behind the tip and parallel to it. It is probably a new genus, but, 

 without the fruit, I do not venture to propose it as such. 



DOnBTFTJI. SPECIES. 



BiDABLA iNODOBA, Dcm. in DC. Prodr. viii. 624. " From sandy places near Pondi- 

 cherry (Cynanchum inodorum v. Ganosma inodora, Lout'. M. Coch. 166). A climber 

 -with fistular glabrous stems, leaves rounded-ovate or -lanceolate quite glabrous base 

 rounded or cordate, petiole slender, peduncles short, pedicels longer, flowers puberu- 

 lous, tube hairy within, stigma conical emarginate exceeding the anthers " (Dene. I.e.). 

 1 haye no idea what this is ; it is probably a very common plant. 



81. GOKGROXTEIMCA., Dene. 



Glabrous twining shrubs or undershrubs. Leaves opposite. Cymes various, 

 axillary ; flowers small. Calyx 6-partite. Corolla urceolate subrotate or 

 broadly campanulate, lobes narrowly overlapping to the right. Column short ; 

 coronal scales adnate to the bases of the anthers or 0. Anther-tyis inflexed, 

 concealing the stigma ; pollen-masses solitary in each cell, ovoid, waxy, erect ; 

 stigma convex davate or conical. Follicles acuminate. Seeds comose. Disibtb. 

 Species about 10 ; Asiatic, African, and Australian. 



* Corolla nearly rotate, tube short. 



1. G. nepalense, Bene, in DC. Prodr. viii. 624; glabrous or cymes 

 puberulous, leaves large oblong or ovate acuminate base rounded or cordate,

 coronal process small recurved or obsolete. Qymnema nepalense. Wall. Tent.

An extensive twiner, shoots and cymes puberulous. Leaves 3-6 by 1^-3| in., 

 membranous, nerves arching ; petiole 1-2 in. Peduncle 2-6 in., generally branching 

 into 3 long divaricate arms, each bearing three many-fld. umbels, pedicels short. 

 Sepals ovate. Corolla J in. diam., yellow. Follicles slender, 24-3 by A in.

 difference between G. sagittatum and nepalense. The processes at the base of the 

 column vary very much. 



** Oorolla-tube inflated, equalling or exceeding the lobes in length.
