GRASSES OF MICHAUX’S FLORA BOREALI-AMERICANA. 151 
S. juncea 1,., for which reason it was changed by Poiret to 8. canadensis.¢ Wence this 
species should be called Stipa canadensis Poir. (Stipa macounii Scribn. in Macoun, 
Cat. Can. Pl. 5: 390. 1890.) The species of Britton’s Manual described as Oryzopsis 
juncea (Michx.) B.S. P. should be called Oryzopsis pungens (Torr.) (Milium 
pungens Torr. in Spreng. Neue Entdeck. 2: 102. 1821.) 
Erianthus saccharoides Michx. 
There are two sheets of this, both labeled by Michaux, but no locality is given. 
They belong to the species described in Small’s Flora under this name. This species 
was described by Walter in 1788 as Anthoranthum giganteum. Wis specimen is 
among the few grasses preserved in his herbarium at the British Museum. In both 
types the panicle is tawny and the awn straight. The specific name can not be taken 
up because there is an Erianthus giganteus Muh,’ based upon Andropogon. alope- 
curoides Land described in his Descriptio Graminum.¢c The awn is there stated to be 
twisted, asin the Linnean plant. 
Erianthus brevibarbis Michx. 
“Tn collibus desertis ab amnio Wabash ad Ostium Missouri 5 diebus distantibus.”’ 
The specimen belongs to the species described in Small’s Flora under this name. The 
The known 
39 
range as originally published is ‘in collibus Tennassée et Carolinae. 
range is from Delaware southward along the coast to Florida, and west to Louisiana. 
We do not know of its occurrence in southern [linois, as given on Michaux’s label. 
Holcus odoratus |. 
“Tn pratensibus Canada [sign for perennial]..’ The specimen is Savastana odorata 
(L.) Seribn. 
Andropogon macrourum Michx. 
“A Virginia ad Carolina [sign for perennial]."" The specimen is Andropogon glome- 
ratus (Walt.) B.S. P. This agrees with Walter's specimen in the British Museum in 
having roughened spathes, rather loose instead of tightly rolled as in the type speci- 
men of Andropogon corymbosus (Chapm.) Nash (A. macrourus corymbosus Chapm.; 
Hack. in DC. Monogr. Phan. 6: 409. 1889. Curtiss, N. A. Plants 3639¢). 
Andropogon dissitiflorum Michx. 
“In Carolina Georgia Florida.’’ The specimen is Andropogon virginicus Li. 
Andropogon ternarium Michx. 
“Tn regione Wabash Georgia montosa &e.’’ The specimen is Andropogon argyraeus 
Schult. which is A. argenteus Ell., not DC. There isa single rather fragmentary speci- 
men which is undoubtedly this species. Besides the label quoted above, the sheet 
bears two others, but the name 1. ternariin is questioned upon both. One gives the 
locality as “Wabash & Hlinois,’’ the other as Florida. As the diagnosis on the first of 
these two labels states that the staminate flower is pediceled, 1. fureatus Muhl. may 
be referred to. However, the published locality is “in montosis Carolinae.’”? Some 
of the awns of the specimen are somewhat twisted. There appears to be no reason 
why this name (as A. fernarivs) should not betaken upin place of A. argyraeus Schult. 
Andropogon scoparium Michx. 
The label bears the name, but no locality. The published locality is ‘in aridis 
sylvarum Carolinae.”’ The specimen belongs to this species as generally understood. 
The sheet bears another label with *‘ Andropogon avenaceum,”> which has evidently 
been misplaced. 
Andropogon avenaceum Michx. 
“In regione Hlinoensium [sign for perennial]... The specimen is Sorghastrim 
nutans (L.) Nash (Andropogon nutans L.), agreeing with the Linn:ean specimen in 
having once-bent awns.
