72. Panicum brachyanthum Steud. 



Panicum brachyanthum Steud.- Syn. PI. Glum. Ir 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. S. Dept. Agr. Div. Bot. Bull. 8: 36. 1889, not 

 Doell, 1877. Vasey cites "(P. angustifolium, Chap, non Ell.)," 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. Vas3y, 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.

 serted, 5 to 15 cm. long, about as wide, 

 the branches few, scabrous, the lower

 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.
