3) PANICUM COMMELINAEFOLIUM Ashe, sp. nov. 
Culms tufted, erect or ascending, 8—15' high, stout, 
more or less pubescent. Sheaths more than half the 
length of the internodes, generally softly pubescent ; 
ligule a mere margin. Leaves crowded, longer than the 
internodes, spreading or ascending, ovate-lanceolate, 
acuminate, abruptly narrowed to the cordate base, 11-15 
-nerved, 2—3' long, 6’—14" wide, glabrous abeve, min- 
utely pubescent beneath, the margins ciliate and serru- 
late. Panicle ovate, 2—3' long, short-peduncled, 
branches numerous, spreading ; spikelets smooth, ellipti- 
cal, 14° long, the first scale one-third the length of the 7- 
nerved second and third. Later forms branched above, 
with smaller leaves, the smaller panicles partly included 
in the sheaths. 
A species having the foliage of P. Portertanum, and the spikelets of 
P. commutatum. Based on material collected by Dr. J. K. Small near 
Stone Mt., Ga., Aug. 1—6, 1895, and distributed as P. commutatum.

from a short rootstock, often covering many square feet, 
1o6-—3° high; stem glabrous or nearly so above, papil- 
losehispid below. Sheaths of primary stem one-half as 
long as the joints or more, the iower ones papillose-his- 
pid, the upper glabrous, the panicle long-peduncled ; 
sheaths on the branches much crowded and overlapping, 
papillose-hispid, concealing the small panicles; ligule
