95. Panicum fusiforme Hitchc. 
Panicum neuranthum ramosum Griseb. Cat. Pl. Cub. 232. 1866, not P. ramosum L. 
1767. ‘Cuba occ. (Wrfight]3454).”’ The type, in the Grisebach Herbarium, was col- 
lected by Charles Wright in western Cuba in 1863, and is numbered ‘‘900 = 3454.” 
It is the autumnal form. This species was also distributed by Wright under nos. 3453 
and 3461 in part.¢ 
Panicum fusiforme Hitche. Contr. Nat. Herb. 12: 222. 1909. Based on P. neu- 
ranthum ramosum Griseb., not P. ramosum L. 
DESCRIPTION. 
Vernal form similar to that of P. angustifolium; culms 30 to 70 cm. high, the basal 
and lower blades narrower and at least the lowermost softly pubescent beneath, the 
longitudinal wrinkles obscure, the leaves more or less clustered toward the base of the 
culms, the panicles thus long-exserted; 
spikelets 3.3 to 3.5 mm. long, 1.4 to 1.5 
mm. wide, elliptic, long-attenuate at 
base; first glume two-fifths the length of 
the spikelet, usually obtuse, second 
glume and sterile lemma exceeding the 
fruit and somewhat beaked beyond it at 
maturity, the pubescence as in P. an- 
gustifolium; fruit 2.5 mm. long, 1.4 to 
1.5 mm.wide, broadly elliptic, obscurely 
puberulent at the subacute apex. 
Autumnal culms erect or reclining, 
under favorable conditions formingdense, 
bushy clusters 30 to 60 cm. in height; 
blades soon involute, 3 to 5 cm. long; 
spikelets more turgid than those of the 
primary panicles, 3.5 to 3.8 mm. long, more pointed; fruit more turgid. 
Panicum fusiforme can be distinguished from P. angustifolium in the vernal state by 
the larger and more pointed spikelets and the soft pubescence on the lower surface of 
Fia. 164.—P. fusiforme. From type specimen of 
P. neuranthum ramosum Griseb.
