C. repens, Elliot. 
This beautiful species of cypress-grass, is, for tbefirst time, 
described by Dr. Muhlenburg, in his “ Descriptio Uberior 
Graminum.’^ It grows to the height of three feet in this vi- 
cinity, but seldom exceeds two. 
Whole plant glabrous ; having only the margins of the invo- 
lucre-leaves scabrous. Mr. Elliot is, I think, right, in his 
suspicion of the identity of his C. repens and the above species. 
A careful examination of the C. plymatodes of Muhlenberg 
(of specimens given me by the doctor), by Mr. Elliotts de- 
scription, leaves no doubt in my mind, that the plants are the 
same. Whether the C. tuberosus of VahU as quoted by Pursh, 
is also identical with these two, I cannot say. 
It delights in moist places In the damp meadow^s, near rivu- 
lets, in Jersey, near Woodbury, and along the course of the 
Delaware, about five miles below Philadelphia. Not very fre- 
quent. Perennial. August. 
6. C. culm triquetrous nearly naked. Radical leaves 
linear-lanceolate, smooth, culm solitary. Umbel 
compound. Involucrum 3-leaved longer than the 
peduncles. Peduncles smooth, numerous (6 — 10) 
triquetrous. Involucellum three leaved, pedi- 
cels numerous, spikelets three, compressed, alter- 
nate, ovate, 8-flowered. Calix glumes ovate, acute, 
brown, nerved on the margins. Siam* 3, yellow. 
Pistillum trifid. Seed three-sided, white, beard- 
less. Root creeping, terminating in tubers. Spike- 
• lets very often viviparous, and then cylindric, 
scales nerved, acuminated. MuhU Descrip* Ube- 
rior* Gram* p. 19. 
Readily distinguished by its small conglomerated peduncu- 
lated spikes, of a bay colour. About one foot or eighteen

Jersey, not more than a mile from the Woodbury road. Pe- 
rennial. August, September. 
7. C. stem round, naked, thick, pointed. Radical 
leaves broad and smooth. Umbels three leaved,
