In the original description specimens are cited as follows: "Brewer 1665; Dr. William Hille- 

 brand 2313; Bolander 6201-, 6209." (The Hillebrand number should be 2315). All of these are the 

 present species, except Bolander 6201, which is Carex lept.opoda and does not answer Olney's descrip- 

 tion. Under the circumstances Bolander 6209 is taken as the type.

 stocks. Culms triangular. Opaque part of leaf-sheaths not red-dotted or cross- 

 rugulose, but sometimes green striate. Spikes 2 or 3 up to 20, with several to 

 many perigynia, the terminal gynaecandrous, the lateral pistillate or gyna> 

 candrous, simple, the inflorescence varying from capitate to moniliform. Lower 

 bracts from inconspicuous to very conspicuous. Perigynia varying from scale 

 like or flat (except where distended by achene) to thick and piano convex, the 

 body subulate to reniform, narrowly to broadly wing-margined, appressed or 

 ascending or spreading, little corky-thickened at base, prominently beaked, the
