Except in the direction of the indumentum this looks more like a variety of 

 Z. montana than of L. lanata or L. Candida (mihi).

 A herb with stems sometimes woody below, usually numerous from 

 a woody rootstock, 8"-2 ft. long, suberect or diffuse or clambering

 districts of the Central and Southern Areas ! Fl., Fr. c.s. and h.s. 



Bentham describes the flowers as " white ? but oftener purple," but 

 they are alivays white. The calyx is sometimes glabrous within

 lateral small recurved lobes and large broad terminal spreading

There are all manner of transitions between the following forms, which can 

 scarcely even rank as varieties :— 



(a) montana, proper {Wall. Cat. 2056, 2525). 



Branches tomentose, leaves shortly petioled, vmder 1-2"', ovate, very 

 obtuse, crenate, sericeo-lanuginous beneath, villous above. Calyx

Parasnath, Clarke ! Kalahandi plateau, but with leaves less obtuse ! 



(b) Var. mollissima. Syn. L. mollissima, Wall. (No. 2054). 

 Rootstock very woody. Branches diffuse reflexed hairy {Wallich, As.
