Erect shrub, often almost a small tree, very variable, stems 

 stout, cylindrical, glabrous, the younger ones compressed ; 

 1. varying much in size, 2^-10 in. (or even more), lanceolate 

 or oval-lanceolate, tapering at base, gradually acuminate, 

 acute at apex, glabrous, rather stiff, strongly plicate, lat. veins 

 numerous, very oblique, strong, impressed above, very pro- 

 minent beneath, petiole \-\\ in., stip. connate, quite free from 

 petiole, sheathing, loose, often i^in. long (in the larger forms) 

 and covering whole internode or overlapping, glabrous, trun- 

 cate, with a few deciduous setaceous teeth, persistent and 

 becoming white and scarious; cymes numerous, terminal and 

 from upper 1. -axils, in large spreading panicles, ped. as long 

 as or longer than cal., cal.-limb campanulate, segm. triangular 

 or linear, acute, deciduous in fruit ; cor.-lobes narrowly oblong, 

 as long as tube, hairy within ; capsule nearly \ in., broadly 

 oblong-ovoid, splitting into 2 ventrally dehiscent carp. 

 Var. /3, pilosa, Thw. I. c. C. P. 2819. 



Stems hairy ; 1. linear-lanceolate, often very narrow, more 

 or less hairy beneath ; cal. -segm. very short.

Very stout and woody; 1. oval or ovate-lanceolate, very 

 coriaceous, petiole dilated ; fl. very large, cymes dense ; cal.- 

 segm. long-lanceolate, acute, persistent; capsule over \ in., 

 turbinate-ovoid. 



Throughout the montane zone; very common. Var. S, Kotiya Kande, 

 Dickoya. Var. e, Maskeliya ; Adam's Peak; Galagama. Fl. March- 

 June ; white. 



Endemic (?). 



Extraordinarily variable, and might be divided into several species. 

 The commonest form at the higher elevations is var. major, Thw. (C. P. 

 96). Var. e turns yellow in drying. The flowers are remarkably dimor- 

 phic, as noticed by Arnott. I refrain from quoting Bedd. Ic. t. 31, which 

 scarcely appears to represent any form of this species.
