Descriptive Characters of 



and J. Hooker Orcobolus pectinatus from Lord Auckland's 

 Group, Campbell's Island and New Zealand. Thus, it ap- 

 pears, that all these islands possess only an isolated represen- 

 tant of the genus. 



30. Carex Polyantha. 



Tall ; leaves broad-linear, nearly flat, keeled, with the erect 

 triquetrous sterna little scabrous ; male spikes 4 — 5, elongate- 

 cylindrical, the lowest ramified by several short ones ; female 

 spike s 3 — 5, very long, cylindrical, the lowest long peduncu- 

 late with remote flowers at the base ; lower bracts very long 

 foliaceous, auriculate but not vaginate at the base ; stigmas 

 two; fruit brown, ovate, sessile, glabrous, dotted, on both 

 sides convex and distinctly streaked, abruptly terminated into 

 a very short bidentate beak, as long as the lanceolate-subu- 

 late black bracteoles; caryopsis compressed, round-ovate, 

 straw-yellow, shining, even. 



In the vallies of the Upper Mitta Mitta, near Mount 

 Hotham. 



More allied to Carex acuta and paludosa, than to any of 

 the Australian, Antarctic and New Zealandian species.
