Boott, who used the name C- glaucescens, as later writers have done. 
The priority of Muhlenberg’s name does not appear to have been 
noticed, ar. androgyna, Curtiss, Sill. Journ. xliv. 84, is a 
form with androgynous terminal spike, “flowering in October, 
quite polymorphous.” Var. polystachya, Curtiss, Sill. Journ. 
vii. 410, is a small and polystachyous autumnal form “ appar- 
ently produced by having been cropped early in the season by 
cattle” These varieties are merely occasional forms. Otto von 
Beckeler in Linnea, xli. 292 (1877) refers the species to C. 
Brasiliensis, St. Hilaire, a later and apparently distinet species. 
Margins of ponds, mostly in pine barrens, Virginia to Florida 
and Texas. / . 
3. C. crtnrra, Lam. This plant grows from Canada to 
South Carolina and Texas. It is widely variable in the size of 
of any permanence is the var. gynandra, which is distinguished 
by rough sheaths, more loosely flowered, pistillate spikes and 
stouter scales. ©. Mitchelliana, Curtiss, Chapm. F lora, 536, is a 
form with an androgynous terminal spike. Olney in his Exsic- 
cate quotes C. Caroliniana, Schw. An. Tab., as a synonym 0 one 
form of C. gynandra, but I can trace no resemblance to any form 
of C. erinita in Schweinitz’s key which leads to his C. Caroliniana. 
he synonomy of the species, so far as I know it, may be ar- 
ranged as follows:
