Var COLORATA, 



Scales consi)icuously purple-margined, giving the head a dark 

 appearance. — Chiefly southward, evidently, and not conuiion. 

 In a species which is characterized by green heads, such a varia- 

 tion appears to be worth a varietal name. 



The C. varia of all later botanists may be called 



48. — Carex communis.

Mostly lower than the species; leaves very numerous, very 

 broad and bright green, conspicuously shorter than the culm ; 

 staminate spike very short (usually only a fourth or third inch 

 long), closely sessile, inclined and inconspicuous; lowest bract 

 leaf-like, often an inch or two long. Knolls in woods: Cheshire 

 Co., N. Hampshire, Bailey; Ionia Co., Michigan, Wheeler, and 

 Alcona Co., Bailey. In aspect much like C. varia ((T. Eninion- 

 sii), but is at once distinguished by the broad leaves and large 

 perigynia.

O Utrbiitata, Liebm, Mex. Hal v. "j"] (1850), v. s. Hb. Liebm., 

 referred to this species by Boeckeler (Engler's Bot Jahrb. 

 i. 364), is a good species, distinguished, among other 

 things, by its strongly many-ribbed perigynia. Future 

 observers may find that my C. rigens is a large, stiff, and 

 more developed form of C, tiirbinata, (See No. 94).
