paucioribus, latioribus, paucifloris • pedunculis longioribus; 
perigyniis majoribus ; squamis masculis obtusis. 
This very interesting species was discovered by Mr. Carey in 
woods at Auburn, New York, in 1832, growing among decayed 
leaves, not in swamps, as stated by Dewey, and it was named after 
Mm by Dr. Torrey. For some time this was the only known 
habitat, until Mr. Sullivant found it plentifully near Columbus, 
Ohio.

Culmi ex eadem radice plures, 3-5 vel 8-12 poll, longi, 
debiles, keves, patuli, demum decumbentes; pars spicas ge¬ 
rens 2-11 poll, longa. Folia culmea 2-3, brevia, 1-2 lin. 
lata: radicalia 5-8 lin. lata, 3-5 poll, longa, culmo breviora, 
glauca, mollia: annotina demum pollicem lata, ssepe viridia, 
8 poll, longa, nervis 2 lateralibus prominentibus notata, cul- 
mis breviora. Bractecs 1-3 lin. latse, 1-1| vel 2 poll, longse, 
lanceolatse, spicis suis duplo rarius triplo longiores. Vaginae 
omnes plerumque breves : infima subinde pollicaris. Pedun- 
culi inserti vel breve exserti: infimus nunc If poll, longus. 
Spica mascula 2-4 vel 7 lin. longa, )-l ) lin. lata, plus minus 
pedunculata, nuda, ssepe bractca cuspidata sterili plus minus 
ab ejus basi remota, castanea. Spicce foeminece 3-8 lin. longse, 
1-) lin. latse, 2-5- vel 7-florse (flosculis alternatim dispositis, 
summis ssepe abortivis) : omnes subinserte vel breve exserte 
pedunculatse, erectse. Squamce masculse latiores, obtusse, mu- 
tics : vel subacutse, infima nunc breve cuspidata: castanese 
margine pallidse : foeminese ovatse, acutse, muticse vel cuspi- 
datse, albse vel castanese. Perigynium l T 5 o~nr bn- longum,

duum. Aclienium l T 3 ff lin. longum, -fa lin. latum, ovale, acute 
triquetrum, castaneum, basi styli apiculatum. 
Habitu ad C. laxifloram, var. plantagineam, accedit. Differt 
culmo spicis bracteisque brevioribus; spicis foemineis pauci¬ 
floris, subinserte pedunculatis, nusquam compositis; perigy¬ 
niis brevioribus, utrinque prsecipue basi minus attenuatis, 
acutangulis, ore integro, nec oblique secto : nervis pluribus 
tenuioribus: olivaceis, furfuraceo-asperulis, facile deciduis; 
foliis radicalibus brevioribus, latioribus. 
Ad C. digitalem, W., propius attinet. Tamen ab ea et a 
C. retrocurva differt, spicis erectis, paucifloris, subinserte pe¬ 
dunculatis ; bracteis brevioribus; pedunculis validioribus; fo¬ 
liis latis; perigyniis deciduis. A C. retrocurva etiam spicis 
laxifloris, nec unquam basi masculis. 
This pretty species has been frequently confounded with C. laxi¬ 
flora, Lam., ( C. anceps ,) and also considered a wide-leaved variety 
of C. digitalis. Its characters are so constant that I think Mr. 
Carey was right in separating it. I find in 240 specimens— 
90 with 3 spikes. In all 1 male.
