spikelets well distinguish this from P. ctliatum E11., to which it is most 
nearly allied.”’ Florida and Cuba. 
71) PANICUM LONGIPEDUNCULATUM Scribn. Stems 
erect, somewhat clustered, 6’—10’ high ; sheaths villous 
with spreading hairs, or nearly glabrous inflated; 
ligule hairy. Stem leaves few, distant, ascending, 
2”’—3”’ wide, lanceolate, narrowed to the somewhat 
rounded base, soft pubescent on both sides, the margin’ 
ciliate ; basal leaves rather numerous, as long and as wide 
as those of the stem, pubescent on both sides, ciliate on 
the margins. Panicle about 2’ long, oval, the axis pubes- 
cent, branches fascicled, spreading, slender ; spikelets 
obovate, barely 4”’ long, obtuse, the first scale one-half 
the length of the smooth 7-nerved second and third, ped- 
icels 3 to 4 times the length of the spikelets. 
Color pale green. Ditch banks and wet sandy places, eastern North 
Carolina to Florida. North Carolina: Ashe; Roanoke Island, June, 
1898. Florida: Curtiss ; Jacksonville. The basal leaves of this spe- 
cies, like those of P. ciliatum, are much more prominent than the stem 
leaves, and the stems, having rather few leaves, appear rather naked. 
The autumnal stage is not fasciculately branched. 
72) PANICUM MICROPHYLLUM Ashe, sp. nov. Some- 
what tufted, 8’—20’ high, slender, ascending or reclin- 
ing, glabrous or pubescent with long white ascending 
hairs. Sheaths glabrous or pubescent, very much short- 
er than the internodes; ligule pilose. Stem leaves dis- 
tant, ascending, linear-lanceolate, 1’ long or less, 1”—2”’ 
wide, generally more or less villous. Basal leaves crowd- 
ed, 1’ or more long, 3’’—4”’ wide. Late forms somewhat 
fasciculately branched above. Panicle long-peduncled, 
about 1’ long, the slender branches ascending ; spikelets, 
4’*—%”’ long very broadly obovate, the minute first scale 
acute, one-fourth the length of the 7-nerved second and 
third. 
Related to P. angustifolium. Collected by the writer June, 1898, at 
Chapel Hill, N. C.,in moist sunny woods.
