Culm about a foot high, 3-sided, glabrous ; leaves subradical, 

 linear, smooth, striate, shorter than the culm ; spikes three, up- 

 per one staminate below, short-pedunculate ; two lower spikes 

 ovate, sessile, short, close-fruited, and the lowest with a long 

 leafy bract j stigmas three; fruit ovate, 3-sided, obtuse, and 

 longer than the ovate and acute scale; whole plant pale green. 



Found in North Carolina by Rev. M. A. Curtis, and is un- 

 doubtedly the true plant of Michaux, as he gives the same locality, 

 though it has been thought to be a variety of C. hirsiita, Willd. 

 But this last is a hirsute plant, with much larger spikes and a 

 pistillate scale equalling the fruit. There can be no doubt that 

 Michaux would have mentioned the hirsute leaves and culm if 

 they belonged to C. triceps. It is now evident that C. virescens, 

 Muh., C. hirsuta, Willd., and C. triceps, Mx., correspond to the 

 description of their authors, and this series is now complete.

Spica composita, spiculis subquinis ovatis alternis approximatis 

 sessilibus inferne staminiferis bistigniaiicis ; fructibus ovato-lan- 

 ceolatis ore bilobo, squama ovata acuta subduplo longioribus. 



Culm slender, erect, 3-sided, more than a foot high, with linear- 

 lanceolate leaves towards the base ; spikelets about five, ovate, 

 sessile, rather near, alternate ; stamens chiefly at the base of the 

 upper spikelet, with oblong and obtuse scales ; stigmas two ; 

 fruit ovate-lanceolate, somewhat concave or flat below, smooth, 

 with a short two-lobed orifice, and with ovate and acute scales. 



Found in the mountains of Carolina and Georgia by S. B. Buck- 

 ley, and named C. Gebkardii, Schk., to which, as well as to C. 

 scirpoides, it is related. From the latter it is separated by seve- 

 ral characters, and from the former in its spikes, fruit, &c. C. 

 Gebkardii is a shorter, thicker and heavier plant, has about nine 

 spikelets, and its fruit oblong, roundish, sharply acuminated into 

 a short beak, with an ovate and abruptly acute or obtusish scale. 

 The resemblance between our plant and the figure of C. Geb- 

 kardii in Schkur is much greater than between the two plants 

 as we have compared it with specimens of C. Gebkardii from 

 Germany. It has accordingly been named in honor of the dis- 

 coverer, an active and successful botanist.
