CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



This species is allied to C. wacrostachya, from which it differs in the looser panicle 

 with longer ascending lower branches. The broad flat blades distinguish it from the 

 common form of C. macrostachya in Texas. A specimen ( Millie r 2051, in N. V. Bot 

 Gard. Herb.) from Orizaba, Mexico, appears to be this species.

DOUBTFUL SPECIES. 



Setaria falcifolia Fourn. Mex. .PI. 2: 44. 1886. "Culmo recto, stramineo, 

 oliato, e radice fibrosa orto; foliis longis, falciformibus, angustis, plicatis, acutis, cum 

 vaginis villosis, ligula laciniato-pilosa; thyrso lineari, fasciculis remotis, pauciflori-: 

 chaetocladis scabrioribus parvis, paucis versus basim fasciculi; gluma inferiore 

 mmore quam dimidia spicula; superiore 2/3 floris aequante; (lore hermaphrodite 

 tenuiter striate Absque loco (Jurg. n. 622)." 



Note on Setaria Ach. — Stapf 1 discusses the validity of the names Setaria Ach. 

 and Chaetochloa Scribn. He shows that Setaria was used by Acharius as a subdivision 

 of the genus Lichen and not as a distinct genus. The author of the present revision of 

 Chaetochloa regards the genus Setaria as effectively published by Michaux, since it- 

 was based on the section or tribe of Acharius, therefore invalidating Setaria Ream. 

 Stapf rejects Setaria Ach. because it has not come into general use, and accepts 

 Setaria Beauv. as valid.
