12) PANICUM MALACOPHYLLUM Nash, Torr. Bul. 24: 
198, (1897). Stems somewhat tufted, erect, simple, at 
length much branched; sheaths rather loose, papillose- 
hirsute with spreading hairs; ligule a ring of short hairs; 
nodes barbed. Leaves narrowly lanceolate, acuminate, 
narrowed to the rounded base, soft-pubescent, the lare- 
est about 3’ long, and 5” wide, 7—nerved. , Panicle 
nearly sessile, the branches Hexous, spreading, bearing a 
few short-pedicelled spikelets ; spikelets about 1}”" long, 
obovate, acute, the first scale over one third as long as 
the very pubescent 9-nerved second and third. 
Related to P. Scribnerianum from which it is separated by its soft 
pubescence, somewhat smaller spikelets, and more slender habit.—

13) PANICUM MALACON Nash, Torr. Bul. 24: 197 
(1897). Stems very slender, tufted, erect, columnar, 
smoothish, 16’—24 high. Sheaths much shorter than 
the internodes, the lower smooth, the upper papillose- 
hispid with ascending hairs; ligule pilose. Leaves distant, 
spreading or ascending, rigid, g@laprous or somewhat 
ciliate at the base, shorter than the internodes, oblong 
lanceolate, acuminate, narrowed or somewhat rounded at 
the base, 2}’—4’ long, 3’’—4’’ wide, 7—-nerved. Panicle 
sometimes much exserted, 2’—3’ long, theslender, scat- 
tered, few-flowered branches erect or ascending. Pedi- 
cels two to many times the length of the spikelets; 
spikelets glabrous, broadly obovate, acutish, 15’’—2” 
lone, the first scale 1—-nerved,. one-third the length of the 
9—-nerved second and third. Later stages somewhat fas- 
ciculately branched above, the leaves a little smaller, 
than the primary ones and panicles barely exserted.
