A twining perennial herb ; rootstock tuberous, somewhat flattened like a 

 turnip, emitting many fibrous roots from below. Stems very slender, 

 usually glabrous. Leaves extremely variable. (In typical C. bulbosa 

 they are petio ed and up to 2 in. long, the lowest almost orbicular, the 

 upper elliptic-oblong or obovate, usually apiculate and with a rounded 

 truncate subcordate or acute base.) Flowers few, in peduncled 

 umbellate cymes; peduncle |1 in.'long, pedicels much shorter.^ Calyx- 

 segments % in. long, lanceolate, acute. Corolla less than 1 in. long, 

 greenish, tube inflated at the base ; lobes £ in. long, linear from a 

 triangular base, violet-purple and villous within. Outer corona-lobes 5, 

 minute, inner filiform. Follicles about 4 in. long, terete, tapering to a 

 slender point, glabrous. Seeds % in. long, ovate-oblong, flat. 



In the Doab of the Upper Gangetic Plain near Allahabad (Hb. Kew) 

 also in Bundelkhand (Edge worth), growing on waste land and amongst 

 bushes. Flowers during the hot season. Distrib. : Punjab Plain and 

 southwards to Travancore. Roxburgh states that every part of the plant 

 is eaten by the natives, either raw or stewed in their curries, the fresh 

 roots tasting like a raw turnip, and the leaves and stem like purslane. 



Many of the Asclepiadacece are extremely ornamental. The following 

 belonging to genera which are not represented in the indigenous flora 

 of the Upper Gangetic Plain should be specially mentioned as being 

 often met with in gardens within the area of this flora. Cryptosiegia 

 grandifiora, E. Br. (Tribe Periplocese), a large climbing shrub with 

 glos3y foliage and handsome rose-coloured flowers. It is believed to be
