THE IDENTIFICATION OF WALTER'S GRASSES, 49 



Probably Eragrostis major Host (Briza Eragrostis 

 L.) as identified by Pursh. 



virens? 2. spiculis ovatis, calyce flosculis (7) aecuali, 



pedunculis sublongis. 



Pursh takes up this name from the description, not 

 having seen the plant. It may be a JPanicularia, e. g. 

 P. obtasa Kuntze, which, however, is scarcely common 

 so far south. It might be Uniola latifolia Michx., but 

 the pedicels (" pedunculis"?) of this species are quite 

 long instead of " sublongis." Walter has added to 



^ ^~v^ ^ ^«.,~WX, 



Linnaeus' description the words " pedunculis sublongis." 



44. Poa. Cal. 2-valvis, mill ti flora 8. Spicula subovata; 



valvulis margine scariosis acutiusculis. 



No specimen in herbarium. 



annua 1. panicula brevi diffusa angulis rectis, spiculis 



obtusis, culmo obliquo compresso. 



Probably P. annua L. Walter has merely inserted the 

 word " brevi " in Linnaeus' description. 



simplex 2. panicula diffusa, culmo erecto angulato, 



spiculis remotis trifloris, caly- [P. 80] 



cibus inferioribus unifloris, foliis collo to- 

 mentosis. 



Agrees well with the description of Poa hirsuta 

 Michx. {Eragrostis hirsuta Michx., not Eragrostis 

 simplex Scribn.) as referred by Elliott. 



flava 3. panicula diffusa, spiculis ovato-oblongis niti- 



dis, floribus subobtusis. 



The description agrees very well with that of Grono-
