GRAMINEJ1. 491 



Poa airoides, says : " Scarcely distinct from P. distans, except in habit." 

 After comparing his specimens with those from numerous collectors, 

 we can see no reason for keeping it distinct.

1. MELICA P02EOIDES, Nutt.

 Bolander in Proc. Cal. Acad. 4 (1870), p. 101. 



Hab. Oregon; north branch of the Columbia. — This species has 

 a wide range, and varies so much in size and number of florets, that 

 it is rare to find specimens corresponding with the original ones of 

 Nuttall. He describes the spikelets as having only 2 perfect flowers, 

 but it oftener has 3 or 4, and in the var. inflata of Bolander 6 to 8.
