GEASSES OF MICHAUX's FLORA BOREALI-AMERICANA. 155 



Poa seslerioid.es Michx. 



The name does not appear on the label, but a sheet which answers to the descrip- 

 tion bears the locality "Carol." The plant is Tridens fiava (L.) Hitchc. (Triode a 

 cuprea Jacq.). rt 



Poa compressa L. 



"Environs de Montreal et La Prairie extremite du lac Champlain." The specimen 

 belongs to this species. 



Poa striata Michx. 



" Pensylvania, Virginia, Carolina." The specimen is Panicularia nervata (Willd.) 

 Kuntze (Poa nervata Willd. 1797). 



Poa pectinacea Michx. 



No specimen of this could be found. This is unfortunate, as the species is some- 

 what uncertain. The description points toward the species generally understood and 

 described under the name Eragrostis pectinacea in our manuals. But this is a peren- 

 nial, while Michaux places the sign for annual after the locality, which is given as 

 Illinois. Research in other herbaria at Paris, such as the General Herbarium and the 

 herbarium of Drake de Castillo, may yield specimens collected by Michaux and sent 

 out by Richard, which will determine the identity of the species. 



Poa reptans Michx. 



"Rivierre Kaskaskia in limosis ripariis hujus amnii," the pistillate plant. "In 

 limosis ripariis amnium regionis Illinoensibus [sign for annual]," the staminate 

 plant. These are Eragrostis hypnoides (Lam.) B. S. P. Lamarck b states that his 

 plant is the same as the one collected by Michaux on the Kaskaskia. Lamarck's 

 first description of this, Poa hypnoides, appeared several years earlier. c 



TJniola latifolia Michx. 



"Illinois." This belongs to this species as described in our manuals. No speci- 

 men was found from the published locality, the Alleghany Mountains. 



TJniola gracilis Michx. 



No locality is given. The same as Holcus laxus L. in the Linnsean herbarium, now 

 called TJniola laxa (L.) B. S. P. 



TJniola maritima Michx. 



"Carol, sur la bord de la mer. Sea-side oat." The specimen is TJniola paniculata L. 



Briza canadensis Michx. 



No locality is given. The specimen is Panicularia canadensis (Michx.) Kuntze as 

 described in Britton's Manual. 



Briza eragrostis L. 



"Carol." The specimen is Eragrostis eragrostis (L.) Karst. (Eragrostis megastachya 

 (Koel.) Link). 



A vena mollis Michx. 



"Montreal." The specimen is Trisetum_ spicatwm (L.) Richter (T. subspicatum 

 (L.) Beauv.) The sheaths and blades are pubescent. In some manuals the glabrous 

 form is given this name while the pubescent form is made a variety. However, the 

 Linnsean specimen of Aira spicata is pubescent. 



Avena glumosa Michx. 



"A Canada et Carolina [sign for perennial]." The specimen is Danthonia spicata 

 (L.) Beauv. The plant is glabrous.
