Csespitosa. Radix repens. Cuhnus gracilis, firmus, tri- 
queter, la;vis vel scaber, 6-10-poll, vel demum 2-pedalis, basi 
reliquiis fibratis vaginisque foliorum ferrugineis tectus; superne 
nudus; in uno specimine folio brevi longe vaginante e basi 
spicse 5 poll, remoto munitus. Folia 1—1 lin. lata, culmo bre- 
viora vel longiora, firma, carinata, marginibus car in aqua sca- 
berrima. Spica 10-15 lin. longa, recta: pars staminifera 
5-10 lin. longa, \ lin. lata: basi flosculis foemineis 1-5 alter- 
nis instructa. Squamae masculce oblongse, obtusissimse, albidse, 
ciliatse, medio viridi, demum ferruginese, concolores ; foeminese 
similes, breve cuspidate, vel inferiores foliacese, 10-12 lin. 
longse ; spicam sequantes: summa interdum mutica, nervo ad 
apicem vel paulo infra attingente. Perigynium 2y 0 —3 lin. 
longum, 1-1 y o lin. latum. Achenium perigynio arete tectum, 
2-L lin. longum, lineam latum, basi productum, basi styli in- 
crassata decidua. 
C. phyllostachys maxime affinis, quae tamen differt squamis 
foemineis longissime foliaceis, masculis inferioribus interdum 
enspidatis; perigyniis longius rostratis, nervatis, superne sca- 
briusculis ; rachi angulata, flexuosa; culmo inferne foliis vagi- 
nantibus pluribus instructo. 
In Geyer’s specimens the culm is rough, with only one or two 
female flowers and short cuspidate female scales, and these, but 
especially the male scales, are ferruginous. In one specimen the 
spike is wholly male. In Dr. Price’s and Thurber’s specimens the 
culm is smooth, the female flowers three or five, the female scales 
foliaceous and white, with a green-nerved centre.

A C. ornithopoda, Willd., differt spicis brevioribus, densi¬ 
floris ; perigyniis strigoso-hirtis; squamis ciliatis. 
Torrey, in his Monograph, remarks that he follows Dewey in re¬ 
ferring this species to C. ornithopoda, hut he gives no reference; 
and I have quoted from Silliman’s Journal the only allusion that 
I can find of Dewey to the species under the name orig inall y given 
to it by Mr. Brown. It has not been found in the States.
