MackEnzIE: Notes oN CAREX 243 
perigynia and strongly rough-cuspidate scales of the latter con- 
trast strongly with the smaller brownish green perigynia and short 
scales of the former. For convenience these species may be 
keyed as follows : 
Perigynia much flattened, ascending, rounded at apex, nerved. C. hirsuta. 
Perigynia swollen, nearly orbicular in cross-section, squarrose, taper- 
ing at apex, coarsely ribbed. 
Perigynia 2 mm. long, brownish green; scales not rough- 
cuspidate, C. caroliniana, 
Perigynia longer, green ; scales rough-cuspidate. C. i

New York to Kansas and Texas and eastward along the coast to 
northwestern Florida. I have seen the following specimens :

* The Olney distribution of Carex seems unfortunately to have become mixed, and 
it is not safe to rely on the specimens distributed by him in determining the range of 
any species,
