mulae carinato-compressae squama multo breviores ; flosc. centralis 

 nudus, femineus, cum flosculis masculis quasi nosculum bisquamula- 

 tum hermaphroditum representans. Ovarium sublagenaeforme, gla- 

 brum ; stylus breviusculus, bifidus, ramis crassis exsertis. Ache- 

 nium parvum, in sicco frequentius rugoso-lacunulosum, nitidum v. 

 sub-canescens. 



Hab. — In hill forests, from Ceylon through Hindoostan to Birma, 

 Malacca, and the Indian Archipelago, also occurring in the Philip-

Native names : Harassas lalakki, Sund., according Hassk. ; ielat, 

 Mai., but the same name is applied by the Malays to many other 

 Cyperace^j. 



This would appear a very variable plant, judging from Bentham's 

 identification of H. latifolium with H. trinerve. I myself have not met 

 with the intermediate forms, and I accept here their identity merely on 

 the authority of that distinguished botanist who, no doubt, had a more 

 complete series to compare than I have at present at my disposal. The 

 varieties might be distinguished as follows : — 



Var. a. genuinum, — spicae duplo majores, circ. 2 lin. longae, 

 fiuctigerae, ovales, fusco-canescentes ; achenia oblonga, crasse rostrata 

 praesertim rostro canescente puberulae. — H. latifolium, L. C. Pick.,
