GRASSES OF MICHAUX’S FLORA BOREALI-AMERICANA. 147 
Kunth as described in Small’s Flora. There is only a panicle, but the pilose rachis 
is characteristic. According to the American code Lriochloa mollis is not a valid name. 
It must therefore be changed to Eriochloa michauxii (Roem. & Schult.). (Panicum 
michauxti Roem. & Schult. Syst. Veg. 2: 427. 1817; P. molle Michx., not Sw., 
1788). I do not find sufficient evidence for taking up the name Monachne@ for this 
genus, accepted by Nash.” Monachne is based on AM. unilateralis Beauv. and Sac- 
charumreptans Lam. The former species has no description and can not be identified 
from the plate, though it is evidently some species of Eriochloa, The latter does not 
belong to the genus Eriochloa. 
Panicum capillare L.. 
“A Pensylvania ad Carolinam,’’ This is similar to the Linnean plant, that is, the 
large erect form with broad leaves, as commonly understood, 
Panicum dichotomiflorum Michx. 
This is the species which in the United States has been going under the name of 
Panicum proliferum Lam. An examination of the latter plant in Lamarck’s herbarium 
shows that it has been misunderstood. It is Panicum miliare of Asia. In the original 
description ¢ the author states that the plant was cultivated in the jardin du Muséum 
and that its native country was unknown, although he ventured the guess that it 
might be from Virginia or some other part of North America. He also mentions seeing 
specimens of this in Vaillant’s herbarium. The plant in Vaillant’s herbarium is the 
same. This species was distributed in several of the larger herbaria under the name 
of Panicum proliferum. Pursh took up this name for our plant and has been followed 
by later authors. Michaux’s name appears to be the oldest for this. The type of 
P. dichotomiflorum is in the herbarium of Drake de Castillo. It was sent by Richard, 
having been collected by Michaux ” the type 
oe 
ad occidentem montium Alleganis,”’ 
locality as published. The specimen (a very poor one) in the Michaux herbarium 
is labeled, ‘-in regione I]lineensium.’’ 
Panicum virgatum L, 
“A Pensylvyania ad Georgiam ad ripas fluviorum, copiose in occidentalibus regioni- 
bus [sign for perennial].’’ A second label reads, ** Pres le Debarquement du vieux 
* * * Sur Coper River, Carolina, * * * Rare en basse Carolina.’ The speci- 
men belongs to this species. 
Panicum anceps Michx. 
“Tn herbosis humidis Carolina, Virginiae, Georgiae [sign for perennial]. Mété avec 
le P. melicarium.”’ The same as Panicum rostratum Muhl., a later name. 
Panicum scoparium Lam. 
‘In pratis sylvestris Carolina [sign for perennial].”° The specimen belongs to this 
species—that is, Panicum viscidum Ell. (1816) and is identical with Lamarck’s 
type, which was received from Michaux. 
Panicum latifolium I.. 
“In pratis sylvestris Virginiae, Carolinae, [sign for perenmial|.”’ A) somewhat 
pubescent autumnal state of Panicum bosedi Poir. (Panicum portertianum Nash, 
as described in recent manuals). 
Panicum pubescens Iam, 
“Tn pratis sylvestris Carolinae [sign for perennial].’” The autumnal state of Pani- 
cumscoparium Lam. This was not found in the herbarium of Lamarck, who states that 
he saw the plant collected by Michaux in South Carolina. In the Drake de Castillo 
herbarium is a sheet of specimens from Michaux sent by Richard. The left-hand spec-
