TRIANDRIA MONOGYNIA 37 



subulate or long-lanceolate, slightly ventricose, smooth, indistinctly nerved, ta- 

 pping to a long beak, orifice bicuspidatc, with the slender points abruptly reflex- 

 ed. Seed oblong, obtusely triangular. 

 Hab. Swamps, in the Mica Slate: Geo. Meredith's : rare. Fl June. Fr. July. 



Obs. Found by D. Tcwnsend, Esq. in 1829. Our plant is much taller, and yet 

 more slender, than the specimens which I have collected in New Jersey ; constitu- 

 ting, I think, a pretty distinct variety. The Jersey specimens approach more, in 

 habit, to the C. xanthophysa, Wahl. than curs. 



+ -j- Pistillate Spikelets on exsert Peduncles, partly sheathed at base. 



2fx C. ANCErs, Muhl. in mild. Staminate spikelet pedunculate, 

 linear-oblong, roundish ; pistillate spikclets 2 or 3, distant, slender, 

 loose-flowered, the lower ones pedunculate ; fruit obtusely triangular- 

 ovoid, striate, subpedicellate, or narrowed at base, a little longer than 

 the ovate cuspidate glume. Beck, Bot. p. 439. Icon, Dew. Caric. in

TWO-KDGEI) CAREX. 



Culm 9 to 18 inches high, acutely triangular, with the sides of unequal width, 

 somjtinu'S nearly ancipital above, rather smooth, leafy. Leaves variable in 

 breadth ; radical ones lanceolate, soino of them nearly an inch wide and 4 to 9 or 

 12 inches long, scabrous on the margin, nerved, glaucous, living through the win- 

 ter; those of the culm much narrower, with white membranaceous sheaths. Sta- 

 minate spikelet with the peduncle compressed, originating from the bract of the 

 iij per pistillate one *, glumes oblong, rather obtuse, often acute. Pistillate spike- 

 lets 2 to 5, more commonly 2, distant, about an inch long, loose-flowered, with a 

 zigzag or flexuose rachis; the upper one nearly sessile, the others on ancipital 

 peduncles, supported by leaf-like bracts with short sheaths ; glumes broad -ovate, 

 •btuse, mucronate, a little shorter than the fruit. Fruit triangular-ovoid, or obo- 

 void, attenuate at base, smooth, conspicuously striate, alternate and distant on the 

 rachis, with a short and often oblique beak* Seed triquetrous, puucticulate, red- 

 dish brown, angles yellowish. 



Hab. Rich, hilly woodlands : Bath, &c. frequent. . Fl. April— May. Fr. July. 



Obs. There seems to be some confusion between this and the C. conoideu, oT 

 I\Jnhl. See Gray, and Dewey, I. c. 



26. C. oligocarpa, Schk. Staminate spikelet pedunculate, rather 

 short ; pistillate spikelets about 3, pedunculate, few-flowered ; lower pe- 

 duncles elongated ; fruit triquetrous, striate, smooth, with a very short 

 oblique beak, longer than the ovate acute glume. Beck, Bot. p. 440.
