GRASSES OF MICHAUX’S FLORA BOREALI-AMERICANA. 145 
Trichodium laxiflorum Michx. . 
“Cornucopiae hyemalis Walt. Hab. in pratensibus apricis a Canada ad Floridam 
[sign for male].’’ The specimen is Agrostis hiemalis (Walt.) B.S. P. 
Trichodium decumbens Michx. 
“Hab. in Carolina pracsertim in umbrosis ripariis amnium. Trichod. (certissime) 
majus Cornucopiae perennans Walt.’ The specimen is Agrostis perennans (Walt. ) 
Tuckerm. 
Alopecurus aristulatus Michx. 
No specimen labeled with this name could be found, but there is a very poor speci- 
men of an Alopecurus from which the spikelets have fallen, leaving the axis of the 
spike, and this is labeled “ Alopecurus breviaristatus Hab. in Canada ad ripas Lacus 
Champlain legi {sign for perennial]."’ As Michaux’s description states that the plant 
has an erect culm and scarcely exserted awns, there is no doubt that the species is 
Alopecurus aristulatus, as usually understood. 
Phalaris arundinacea I. 
The specimen belongs to this species. 
Phalaris villosa Michx. 
“Tn Sabulosis Carolinae.’ 
as usually understood. 
’ The specimen is Anthaenantia villosa (Michx.) Beauv, 
Paspalum setaceum Michx. 
“Tn aridis apricis Carolina, Georgia [sign for perennial].”” Terminal spike single, 
slightly curved; spikelets glabrous, 1.5 mm. long; blades pubescent. It belongs to 
the species described under this name in Small’s Flora. . 
Paspalum debile Michx. 
“Hab. in Carolina [sign for perennial].’? Blades densely woolly on both sides, 
about 10 em. long and 6 mm. wide; spike single, the culm smooth below the spike; 
spikelets 1.5 mm. long, pubescent. This is Paspalum villosissimum Nash,@ which 
name should give way to that of Michaux. /. debile of Elliott’s herbarium is P. 
blepharophyllum Nash (2. debile Michx.; Ell. Bot. 8. C. & Ga. 1: 105, 1816.) 
Paspalum ciliatifolium Michx. 
“In Carolina, Georgia.’ There are three specimens on the sheet. One without 
spikelets may be eliminated from consideration, also one with pubescent spikelets, 
since the description states that the spikelets are glabrous. The third specimen has 
ciliate blades, these somewhat hispid above, more so below, upper sheath ciliate on 
the margin; spikes 2; spikelets glabrous, 2mm. long. This specimen, which I con- 
sider the type, is in poor condition, but appears to belong to the species described 
under this name in Small’s Flora. 
Paspalum praecox Walt. 
“A Carolina ad Floridam.’’ The specimen belongs to the species as described in 
Small’s Flora. 
Paspalum laeve Michx. 
“In Georgia.’”’? The specimen, consisting of a single culm with three short spikes 
and smooth foliage, belongs to this species, as described in Small’s Flora,
