GRASSES OF MICHAUX 's FLORA BOREALI-AMERICANA. 147 



Kuntli as described in Small's Flora. There is only a panicle, but the pilose rachis 

 is characteristic. According to the American code Eriochloa mollis is not a valid name. 

 It must therefore be changed to Eriochloa michauxii ( Roem. & Schult.). (Panicum 

 michauxii 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.fr Monachne is based on M. unilateralis Beauv. and Sac- 

 charum reptans 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 Linneean 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 c the author states that the plant was cultivated in the jardin du Museum 

 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 "ad occiclentem montium Alleganis," the type 

 locality as published. The specimen (a very poor one) in the Michaux herbarium 

 is labeled, "in regione Illinoensium." 



Panicum virgatum L. 



"A Pensylvania 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. 



"In herbosis humidis Carolina, Virginiae, Georgiae [sign for perennial]. Mete 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 L. 



"In pratis sylvestris Virginiae, Carolinae, [sign for perennial]." A somewhat 

 pubescent autumnal state of Panicum boscii Poir. {Panicum porterianum Nash, 

 as described in recent manuals). 



Panicum pub esc ens Lam. 



"In pratis sylvestris Carolinae [sign for perennial]." The autumnal state of Pani- 

 cum scoparium 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 spee-
