as in the last ; fl. in lax corymbose cymes ; cal.-segm. 

 triangular, acute, nearly equal or one sometimes slightly 

 larger ; cor.-tube tubular-funnel-shaped ; fruit about | in., 

 broadly ovoid, compressed, readily separable from the colu- 

 mella but without splitting into separate carp., smooth, 

 black. 



Montane zone to 6000 ft.; rare. Uva (Thwaites) ; Maskeliya; Hak- 

 gala. Fl. May, June, Sept.; white. 



Also in mountains of S. India. 



Fl. B. Ind. refers to this with doubt K. stricta, Gaertn. (Fruct. i. 122, 

 t. 25, f. S). Gaertner's specimens were collected in Ceylon by Kcenig, 

 but could scarcely be this montane species. 



Ceylon specimens are often nearly glabrous.

A small undershrub, 1-2 ft, with a large, stout tap-root 

 and ascending usually much-branched stems, branches erect, 

 cylindrical, stiff, nearly glabrous, shining, purple; 1. numerous, 

 1-2 in., broadly or narrowly ovate-oblong, nearly sessile, acute 

 at both ends, glabrous, finely ciliate on margin, stip. adnate 

 to base of leaf, short, with 3 or 5 filiform teeth bristly at end ; 

 fl. in terminal spikes which become greatly elongated with 

 fruit ; cal.-segm. acute, the outermost one enlarged into a 

 stiff horn twice as long as ov., persistent ; cor.-tube f in., very 

 slender, very woolly at mouth, lobes \ as long as tube, 

 broadly oval ; fruit about -^ in., ovoid-globular, crowned with 

 cal.-segm. (the large one as long as fr.), glabrous, pale brown, 

 carp, readily separating, plano-convex, not compressed, 

 rounded and keeled down the back. 



Open ground in the moist low country; very common. Fl. Feb.; 

 white or pinkish. 



Endemic. 



Hermann gives ' Wissaduli ' as the native name for this, but no doubt 

 incorrectly (see footnote, Part I. p. 146, under Wissadula zeylaniea). 

 Moon has ' Ela-ratmul,' but I do not find this generally used.
