72. Panicum brachyanthum Steud. 
Panicum brachyanthum Steud. Syn. Pl. Glum. 1: 67. 1854. The only specimen 
cited is, ‘‘ Vinzent Coll. nr. 124. Texas.’’ The type, in the Paris Herbarium, is labeled 
‘‘In sabulosis sylvaticis, Texas, prope coloniam Rusk County, Vincent coll. 124.” 
Panicum sparsiflorum Vasey, U. 8. Dept. Agr. Div. Bot. Bull. 8: 36. 1889, not 
Doell, 1877. Vasey cites ‘‘(P. angustifolium, Chap. non Eil.),” gives a description, 
and follows with the range ‘‘South Carolina to Texas.’’ As this is not primarily a 
change of name, the type is one of the specimens which Vasey had before him when 
he wrote the description. From among those in the National Herbarium upon which 
Dr. Vasey has written the name, we have chosen as the type one collected in dry soil 
at San Bernardino, Texas, October, 1839, by Dr. Ridell, no. 20. This was first named 
by Dr. Vas2y, P. angustifolium Ell. The authority, ‘‘Ell.,” was changed to ‘‘Chap. 
non Ell.’’ No specimens from South Carolina can be found named P. sparsiflorum 
by Vasey nor is the species known from that State. 
DESCRIPTION, 
Plants weakly ascending or spreading from a decumbent base, freely branching from 
the lower nodes; culms slender, 30 cm. 
to 1 meter high; sheaths shorter than the 
internodes, minutely ciliate; blades 5 to 
15 cm. long, 2 to 3 mm. wide, narrowed 
toward the base, often involute and 
scabrous toward the apex, the uppermost 
usually reduced; panicles finally ex- 
serted, 5 to 15 cm. long, about as wide, 
the branches few, scabrous, the lower 
sometimes as much as 10 cm. long, bear- 
ing a few short-pediceled spikelets, 
mostly in twos, toward the ends; spike- 
lets 3.2 to 3.6 mm. long, 1.5 mm. wide, 
elliptic-obovate, abruptly pointed; first 
glume minute; second glume and sterile lemma subequal, the tubercles bearing stiff, 
spreading hairs; fruit 2.9 to 3 mm. long, 1.4 mm. wide, obovate-elliptic, subacute.
