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 . 
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- 
volucrum 1 — 2 leaved. Calix glumes 1-valved, 
the lower ones awl shaped, the rest obtuse, brown- 
purple, the keel green or white. Stamps. Fistillum 
trifid. Seed nearly triquetrous, white, beardless, 
somewhat rough, transversely nerved. Root 
fibrous, Muhl.

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 autumnalis, and near to Scirpus eapillaris, 
of Swartz. It inhabits difierent places from 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 Europe an^plant in my possession, 
these do not, however, differ, except in size. Jersey, frequentj 
this side of the Delaware, rare. Annual. July.
