more or less pubescent. Panicles open, the lower branches 5—7 cm. 
long, spreading or ascending. Spikelets about 1.5 mm. long, elliptic, 
acute, smooth, usually borne in pairs at the extremities of the ultimate 
branches of the panicle ; first glume about one-third as long as the

It is possible that this form is only worthy of varietal rank, 
although the extreme form is very distinct from: Panicum capillare. 
In many cases, however, the two species can only be separated 
arbitrarily. 
12. PANICUM MILIACEUM Linn. Sp. Pl. 58. 1753. — A rather stout, 
erect annual 3 to 8 dm. high. Culms glabrous or hirsute. Sheaths

leaf-blades 10-30 cm. long, 6-16 mm. wide, more or less pubescent. 
Panicle open, rather densely flowered, 12-35 cm. long; branches 
erect or ascending. Spikelets 5 mm. long, acuminate; first glume 
about two-thirds as long as the spikelet, 5 to 7-nerved, acuminate : 
second glume acuminate, equaling the spikelet in length, 13-nerved, 
somewhat exceeding the 7 to 13-nerved third glume which subtends 
an empty palea: flowering glume about 3 mm. long, obtuse, obscurely 
s-nerved, becoming indurated and shining. 
General distribution: in waste places, Maine to Pennsylvania,
