ANDROPOGON WRIGHTI Hackel. 
Rootstock thick. Roots very strong. 
Culms cespitose, 2 to 3 feet high, unbranched, smooth, slightly hairy at the 
nodes. 
Leaves. Sheaths smooth, striate, shorter than the internodes; ligules 1 line 
long, obtuse, smooth; blades 5 to 12 inches long, 2 to 3 lines wide, light green, 
smooth, the margins scabrous. 
Panicle 2 to 3 inches long, consisting of 5 to 7 clustered or approximate spike- 
like branches 13 to 2 inches long, shortly pedicellate, erect, and densely flowered: 
rachis flattened, hairy, ciliate. 
Spikelets about 3 lines long, in pairs, one female, one male. Female spikelet 
sessile, lance-oblong, hairy at the base, sparsely hairy on the back below;; first 
glume thick, 7-nerved above ; second nearly equal to the first, 3-nerved ; third and 
fourta hyaline, fourth with an awn $ inch long. Male spikelet on a ciliate pedicel 
of half its length, about 3 lines long; first glume 9- to 11-nerved at the base, ciliate 
on the margins above; second more acute, 3-nerved, ciliate; third hyaline, nearly 
equaling the second; fourth very minute or wanting. 
PLATE XXI; a, pair of spikelets; b, female spikelet spread open to show the 
parts; c, male spikelet opened. 
This resembles the preceding species, but is smaller and with fewer spikes, It 
is rare, at least north of the boundary
