Stems rather long, straggling, branched, thickened above 

 nodes, glabrous but for two narrow lines of pubescence; 1. 

 2-4 in., lanceolate, tapering to base, acuminate, obtuse, 

 glabrous or pubescent on veins beneath, sparingly lincolate, 

 petiole \-\ in., spikes short, i-i in., pedunculate, terminal and 

 from upper 1. -axils, flat and one-sided ; empty bracts oblong- 

 lanceolate, over \ in., acute, minutely apiculate, with rather 

 scarious borders, ciliate, finely pubescent, floral bracts and 

 bractlets nearly equal, oblong-oval or slightly obovate, obtuse, 

 often slightly emarginate, broadly bordered, finely ciliate; sep. 

 linear, very acute, chaffy ; cor. exserted. 



Montane zone up to 7000 ft.; rather common. Fl. Nov. -April ; white

This is referred in Thw. Enum. and Fl. B. Ind. to R. /onqifolia, Nees 

 and Arn. 1. c. 471, which was based partially on Ceylon specimens from 

 Walker. I do not recognise this species from the descriptions given. 

 R. latior is not given for Ceylon in Fl. B. Ind., but Wight's figure repre- 

 sents our plant very well, save in being more pubescent.
