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 filiformis has been applied to the species of southern Asia, which I think is 
different from our species. 
e 
Elymus virginicus I.. 
There is no locality given. ‘The specimen is similar to the Linnean type, having 
smooth lemmas and awns 2 to 2.5 em. long. 
Bromus canadensis Michx. 
“Canada: Lac St. Jean.’ The specimen is Bromus ciliatus L. lemmas pubescent 
on the margins, glabrous on the back, 
Festuca myuros |..” 
“Env. de Charleston.”’ There are several specimens on the sheet. Some are 
Festuca octoflora Walt.; some are F. seturea Nutt., the lemmas pubescent toward apex. 
The description apples to the latter. 
Festuca bromoides I..? 
“In pascuis Juxta Charleston.” 
The specimen is Festuca octoflora Walt. 
Festuca fluitans I. 
“Canada, Connecticut, Pensylvania.”’ The specimen is Panieularia borealis Nash, 
Festuca polystachya Michx. 
“Tlinois.”’ The specimen is Leptochloa fascieularis (Lam,) Gray, the erect short- 
awned form.

nate form. 
Festuca poaeoides Michx. 
“In Canada [sign for perennial] “Herb. de M. Jussieu Fleuve St. Laurent.”’ 
The specimen is Festuca elatior L., the small form with slender panicle sometimes 
known as F. pratensis Huds. 
Festuca diandra Michx. 
“[linois.”’ The specimen belongs to the species described as Diarrhena americana 
Beauv. in Gray’s Manual and Korycarpus diandrus (Michx.) Kuntze in Britton’s 
Manual. The specific name is invalidated by Festuca diandra Moench. Korycar- 
pus was substituted for Diarrhena by Kuntze & on the strength of a citation by 
Lagasca (“Norye. arundinaceus Ze. Ac. Matr. 18067° Lag. Nov. Gen. 4. 1816). 
Tam 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 Rat, Med. Repos. 
5: 252. ISOS, based on Festuca diandra Michx. 
Poa capillaris |. 
“Carol.”’ The specimen is Fragrostis refracta (Muhl.) Scribn. 
Poa crocata Michx. ; 
No specimen of this could be found, The description applies to Poa triflora Gilib, 
(P. serotina Erhr.). 
Poa hirsuta Michx. 
“Carol.’’ The specimen is Eragrostis hirsuta (Michx.) Nash as described in Small’s 
Flora.
