is insufficient for identification and the type has not been examined. The species 

 does not appear to be described by Lamarck in his Encyclopedia. The name 

 Leptochloa Jiliformis has been applied to the species of southern Asia, which I think is 

 different from our species. 



Elymus virginicus L. 



There is no locality given. The specimen is similar to the Linmean type, having 

 smooth lemmas and awns 2 to 2.5 cm. lung. 



Bromus canadensis Michx. 



" Canada: Lac St. Jean." The specimen is Bromus ciliatus L. Lemmas pubescent 

 on the margins, glabrous on the back. 



Festuca myuros L.? 



"F.nv. de Charleston." There are several specimens on the sheet. Some are 

 Festuca octofiora Walt.; some are F. sciurea Nutt., the lemmas pubescent toward apex. 

 The description applies to the latter. 



Festuca bromoides I..'.' 



"In pascuis juxta Charleston." The specimen is Festuca ortoflora Walt. 



Festuca fluitans L. 



'•Canada. Connecticut, Pensylvania." The specimen is Panicularia borealis Nash. 



Festuca polystachya Michx.

 awned form. 



Festuca distichophylla Michx. 



"In maritimis Carolinae." The specimen is Distichlis spicata (L.) Greene, stami- 

 nate form. 



Festuca poaeoides Michx. 



In (amida [sign for perennial]." ''Herb, de M. Jussieu Fleuve St. Laurent." 

 The specimen is Festuca elatior 1,., the small form with slender panicle sometimes 

 known as F. prati nsis Suds. 



Festuca diandra Michx. 



"'Illinois." The specimen belongs to the species described as Diarrhena amcrinana 

 Beauv. in Cray's Manual ami Korycarpus diandrus (Michx.) Kuntze in Britton's 

 Manual. The specific name is invalidated b/ Festuca diandra Moench«. Korycar- 

 pus wa^ substituted for Diarrhena by Kuntze b on the strength of a citation by 

 Lagasca ("Koryc. arundinaceus Ze. Ac. Matr. 1806" Lag. Nov. Gen. 4. 1816). 

 I am unable to find any evidence that this name was published earlier than 1816. 

 In the absence of such evidence it is best to use Diarina festucoides Raf. Med. Repos. 

 5: 252. I si is, based on Festuca diandra Michx. 



Poa capillaris L. 



"Carol." The specimen is Eragrostis refracta (Muhl.) Scribn.
