number. Involucrum of two short and two very long leaves. 

 Spikes very acute, in fascicles on the rays, seldom crowded. 

 Glumes rather rigid, the carina green and striated, the rest of 

 a chesnut colour. Seed glabrous. Grows on the borders of 

 salt marshes, and is particularly plentiful on the banks of 

 ditches in Hoboken meadows, where it forms large patches. 

 When it grows in overflowed places it is much taller and the 

 rays of the umbel are very distinct. It appears to be confi. 

 ned to the vicinity of salt water.

Root fibrous, perennial. Culm very slender, reclining on 

 other plants, or decumbent, and generally solitary or thinly 

 scattered. Leaves few, short and linear-lanceolate. Umbel 

 simple, generally with one ray from the fascicles of spikes. 

 Involucrum of two long leaves and one short one, very smooth. 

 Glumes with a green carina, and chesnut colored sides, much 

 compressed. Styles very long. Seed grey, smooth. 



A delicate and handsome species, growing in salt marshes. 

 It is rarer than the former, out not uncommon in Hoboken 

 meadows, generally in overflowed situations. It may have 

 been heretofore confounded with C. jlavescens, from which 

 however, it is distinct

Specimens of this plant collected by M. Goldy in Monmouth 

 Co. N. Jersey, agree exactly with Pursh's^/i^ure, but the flow- 

 el's of the panicle arc hermaphrodite, and produce perfect 

 seeds. Its specific character should therefore be altered.

There can scarcely be a doubt but that this is the Milium 

 eiliatum of Muhlenberg, (Descrip. Uber. Gram. p. 77 -J as 

 his description agrees minutely with our specimens, though 

 he does not notice the remarkable radical inflorescence, 

 merely remarking " radix granulosa." Perhaps this char- 

 acter is not constant. Hermaphrodite flowers : Calyx 2-valv- 

 od lanceolate unequal, acute ; the interior shorter and a little 

 cleft at the apex, and both of them 3-nerved, smooth. Corolla 

 2-valved, equal, of the length of the interior valve of the calyx, 

 smooth and nerveless; the exterior clasping the interior 

 valve. Stamina 3 ; filaments a little longer than thegermen; 

 anthers dark purple, plumose. Seed oblong, smaller than in 

 the female flowers. Female flowers : Calyx 2-valvcd ; valves 

 acuminated, the exterior distinct from the interior one, and of
