 2. PODOSEMUM Desvaux, nouv. Bull. Soc. Philom. 2. 189. 18 10. 

 Muhlenbergia in large part of American Authors, not of 

 Schreber, 1791. 

 A large genus of 40 species or more, natives of America, com- 

 ])rising those species with more or less open, large panicles, the 

 branches of which are either drooping or spreading, pedicals slender 

 or capillary, lemmas long-awned, or occasionally shoit-awncd or 

 awnless.^ A single species occurs in our territory. 



^The center of abundance of PodosEmum species seems to be in Western 

 Texas, to which region P. capillare does not a^ppear to extend, it being the 

 center of a group of three species belonging to thir South Atlantic r gion. 

 In a subsequent paper I shall discuss some of the many allies of P. capillare.
