 Uber. Gram. 



Three-sided Rush. 



Easily known by its simple acutely 3-angled culm, and one 

 two or three sessile conglomerated spikes. This and the pre- 

 ceding species are worked into bottoms for fancy, or what are 

 called, rush-bottomed chairs. Grows with No. 5, frequent, 

 July, August.

Autumnal Scirpus, 



A very pretty species from 6 to 10 inches high, readily iden- 

 tified by its lanceolate deep brown spikelets. The numerous 

 stems radiate from the root, in a beautiful manner. In sandy 

 roads and fields, in Jersey, near Kaighn's point, abundant. 

 Annual. ? August. 



eapiiiarisjL. 9. S. culm bristle-form, two inches, triquetrous, 

 nearly naked, cespitose. Leaves sub-radical, alter- 

 nate, bristly, sheathed at the base. Sheath hairy 

 at the mouth. Spikes lateral near the point of the 

 culm, 1 — 4, one sessile, the rest pedunculated, in- 

 vohicrum 1—2 leaved. CallX glumes 1-valved, 

 the lower ones awl-shaped, the rest obtuse, brown- 

 purple, the keel green or white. Stam. 3- Pistillum

 somewhat rough, transversely nerved. Root

This plant, so accurately described above, has at first view 

 the appearance of No. 2. It is also allied, as Dr. Muhlenberg 

 remarks, to Scirpus autumnaiis, and near to Scirpus capillaris, 

 of Swartz. It inhabits different places fiom No. 2, being 

 generally found in sandy roads and wastes, and never, or sel- 

 dom, near water. Dr. Muhlenberg describes it as two inches 

 high. Though generally it does not exceed that height, I 

 have specimens in my herbarium six inches tall. Compared with 

 Willdenow's specimens of the Europeanjplant in my possession, 

 these do not, however, differ, except in size. Jersey, frequent^ 

 this side of the Delaware, rare. Annual. July.
