florescence, more slender and porportionately much longer spike- 
lets. In /. pilosa the glumes are grown to the axis for almost 
their entire length, and there are no paleas or rudimentary pistils 
of a second flower within the floral cavities. 
ANDROPOGON FLORIDANUS n. sp. 
Culms smooth, stout, 4 to 6 feet high, or 2 to 3 feet high and 
more slender; sheaths scabrous, the lowermost slightly com- 
pressed, loose, and much exceeding the internodes, the upper 
shorter than the internodes and terete; ligule very short, ciliolate, 
auricled; leaf-blade 10 to 24 inches long, 3 to 5 lines wide, scab- 
rous beneath, minutely strigose-pubescent above, at least near the 
base, very acute. Panicle 12 to 30 inches long, very much 
branched, branches ascending. Racemes 1 to 2 inches long, 
slender, in 2’s, rarely in 3’s or 4’s, finally exserted, peduncle 
bearded at the apex; rachis slender, 8—10 jointed, the joints shorter 
than the sessile spikelet, bearded, the hairs near the summit of 
each joint 3 lines long. Primary spikelet wanting, the pedicel ex- 
ceeding the sessile spikelet in length, and bearded with hairs 
equalling those of the joints of the rachis. Sessile spikelet 2 lines 
long, lanceolate-acute, with a few short hairs on the callus; first 
glume bicarinate, smooth and somewhat depressed on the back 
and nerveless between the keels, which are minutely aculeolate- 
scabrous above, glabrous below ; second glume boat-shaped, rather 
broadly lanceolate, very acute, I-nerved, scabrous on the keel 
above, ciliate on thé hyaline margins; third glume about as long 
as the second, lanceolate or oblong, hyaline, ciliate on the mar- 
gins; the fourth or flowering glume lanceolate, about as long as 
the third, margins ciliate, terminating in a slender awn, which is 5 © 
to 6 lines long; palea hyaline, about 1 line in length. Spathe 
about 2 to 3 inches long, narrow, and closely enveloping the slen- — 
der peduncles of the finally exerted racemes. Awn slightly 
twisted near the base, the column included within the glumes. 
A stout grass of the low pine barrens, with elongated leaves _ . 
and rather narrow, elongated, much-branched panicle of silky-_ 
bearded racemes. G. V. Nash, 1572, August, 1894. 
ANDROPOGON ELLIOTTII GLAUCESCENS N. var. 
Glaucous throughout, less branched than in the species, and 
the somewhat stouter racemes more densely silky-bearded. © ae
