Culm, leaves, and sheaths beautifully 
striate, and somewhat glaucous. Culm 
one to two feet and a half high, obscurely 
Leaves broad-linear, obtuse ; 
two to three lines wide; cauline ones few 
and short. Flowers in a crowded, termi- 
nal corymb, sometimes with a much small- 
er, pedunculate, lateral fascicle. Bracts 
somewhat exceeding the corymb. Glumes 
ovate, carinate, mucronate, pubescent on 
the back above the middle. Bristles six, 
very short, minutely hispid upward. Sta- 
mens three. Nut nearly orbicular, lenti- 
cular, minutely alveolate under a powerful 
lens. Tubercle about one-third as long as 
the nut, broad at the base, compressed.

Oss. This species is very similar in 
habit to the preceding; but differs im 
having acute, not ciliate leaves, a larger 
nut, and longer bristles. R. ciliata also 
has six bristles, the ordinary number for 
this genus: this species has uniformly

twelve. R. glauca, of Vahl, a native of ~ 
Equinoctial America, has a rugose nut, 7 
and is doubtless distinct from our plant. | 
I have therefore dedicated this species to | 
the memory of its enterprizing discoverer, 
who paid much attention to the genus 
Rhynchospora.

Culm sighiedn inches to two feet hight 
obscurely triangular. Leaves narrow- 
linear, shorter than the culm. Corymbs ` 
about three, densely fascicled and some- 
what few-flowered; the lower one subdis- 
tant, exsertly pedunculate; the two upper 
approximate, subsessile. Pedicels very 
short. Bracts setaceous. Spikelets ob- 
long. Glumes ovate, carinate, with a long- 
mucro; the exterior shorter, obtuse; the — 
inner ones acute. Bristles six, about half | 
as long as the nut, minutely hispid upward. 3 
Stamens three. Style bifid. Nut lenti- 
cular, ovate or round-ovate, smooth. Tu- 
ercle much compressed, with the base as 
broad as the nut, about half its length.

of our plant agree in every respect with a ' 
fragment of Schenus fascicularis from - 
Mx.’s Herb. The description in his £4 
Bor. Amer. applies minutely to our speci- 
mens, excepting the paragraph '*sefulis 
semine levi duplo longioribus ;" whereas, 
in his own plant, and in all the specimens 
I have examined, the reverse is true, the |
