Vaseyana Scribner, but his glumes are elliptical, acntish and entire 

 and rather shortly pubescent, but those of Vaseyana are scabrous 

 and erose to toothed. The lemma is lead-colored, a characteristic 

 of Muhlenbergia. the awn however is very different. Presl's is a 

 simple prolongation of the midrib, from a broad notch caused by 

 the slight extension of the sides of the lemma as lobes, as to the 

 figure, but hLunth in his Agrostigraphia *-d09 says 4k nervo medio 

 sub apice in aristam excedente", or that the awn comes out below 

 the tip, and it is noticeable that he keeps only those species with 

 such awns in the genus. He, however, blunders by putting E. 

 macroura in China which has the awn on the back also, while E. 

 macroura is a Crypsinua, see below. Except for PresFs figure va- 

 rying somewhat his E. strictaand Podossemum distichophyllnm are 

 the same. We know that this species has both entire and notched 

 glumes and that the awn is also short or absent in some forms. As 

 to Bealia, which is congeneric with Epicampes, we find it founded 

 on a weak aunual, B. Mexicans, while this genus has all robust 

 perennials, but lieai himself rightly considers this as of little note 

 by putting B. speciosa here. Epicampes (and including Bealia) is 

 characterized by the (mostly) ivory-white glumes being cylindri- 

 cal, rather stiff but not ribbed, faintly if at all nerved, erose to 

 variously toothed at tip, scarious or rarely hairy, about as long as 

 lemma and embracing it. The lemma is rigid, 3-nerved, oblong to 

 lanceolate, hairy mostly below. The specialized awn arises from 

 just below the tip and below the lobes, forming an offset from the 

 midrib as a raised process which in most species extends down to- 

 ward the middle fo the lemma as a raised and thickened rib which 

 becomes a si:nple rib below. In some species the awn is reduced to 

 a mere knob, but in most species it is a flexuous, purple, scabrous 

 awn, nearly an inch long. Founder evidently recognized the dis- 

 tinction for he separated E. macroura and stricta from it. Benth- 

 am in Journ. Linn. Soc. 19 seems to have failed to recognize the 

 characters, since he describes E. rigens which is a Crypsinna. The 

 species of Epicampes are as follows. 

 Epicampes stricta Presl. 



Epicampes stricta var. distichophylla (Presl.) 



This is Podosaemum distichophyllnm Presl. ReL Haenke. 231 

 and Muhlenbergia Vaseyana Scribner and M. Emersleyi Vasey. It 

 is a form with long-awned lemma and lacerate-tipped glumes.
