GRASSES OF MICHAUX’S FLORA BOREALI-AMERICANA, 155 
Poa seslerioides 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 7'ridens flava (L.) Hitehe.  ( Triodea 
cuprea Jacq.) .@ 
Poa compressa I. 
“Environs de Montreal et La Prairie extremité du lac Champlain.’ The specimen 
belongs to this species. 
Poa stviata Michx. 
“Pensylvania, Virginia, Carolina.”’ The specimen is Panieularia 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 amni,” the pistillate plant. “In 
limosis ripariis amnium regionis Illinoensibus [sign for annual], the staminate 
plant. These are Eragrostis hypnoides (Lam.) B.S. P. Lamarck ® 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. 
Uniola latifolia Michx. 
“THlinois.”’ This belongs to this species as described in our manuals. No speci- 
men was found from the published locality, the Alleghany Mountains. 
Uniola gracilis Michx. 
No locality is given. The same as //oleus larus L. in the Linnean herbarium, now 
called Uniola lava (.) B.S. P. 
Uniola maritima Michx. 
“Carol. sur la bord de lamer. Sea-side oat.”? ‘Phe specimen is (ntola pantenlata L. 
Briza canadensis Michix. 
No locality is given. The specimen is Panicularia canadensis (Michx.) Kuntze as 
described in Britton’s Manual. 
Briza eragrostis |.. 
“Carol”? The specimen is Eragrostis crayrostis (1..) Karst. ( Eragrostis megastachya 
(Koel.) Link). 
Avena mollis Michx. 
“Montreal.”? The specimen is Trisetim spicatum (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 
Linnzean 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,
