Cinna arundinacea I.. 
There is a specimen of C. latifolia (Trev.) Griseb., which is the plant described, and 
a panicle of C. arundinacea L. One label, which probably applies to the first speci- 
men, reads: ‘A Sinu Hudsonis ad Pensylvaniam pracsertim in borealibus Canada 
juxta lacus.”’ A second label, which probably goes with the panicle, reads: “Cinna 
de Linneus. Cinna envoyé par Linn. a Jussieu qui lui avait eté apporté de Canada 
par Kalm.’’ 
Anthoxanthum odoratum I.. 
“Tn Pensylvania.’’ The specimen belongs to this species. 
Leersia oryzoides Sw. 
“In excelsis montibus Carolina.’’ The specimen belongs to this species. In 
another cover is a sheet of L. virginica which is labeled L. oryzotdes, but without 
locality. It is to be noted that Michaux gives /. virginica asa synonym of L. oryzoides. 
By priority of Homalocenchrus Mieg. the name becomes H. oryzoides (L.) Poll. 
Leersia lenticularis Michx.¢ 
“Tn paludosis regionis Hlinoensibus [sign for annual].”’ 
The specimen ® belongs to this species, 1. e., Homalocenchrus lenticularis (Michx.) 
Scribn. 
Dilepyrum aristosum Michx. 
No specimen of this could be found. Tt is, according to deseription and tradition, 
Brachyelytrum erectum (Schreb.) Beauv. and is the type of the form known as B. 
aristatum Roem. & Schult. and Muhlenbergia aristata Pers., though the specific name 
is altered. 
Dile m minutiflorum Michx. 
P 
“In apricis, pratis Kentucky, Ilinoensium pabulum praecstantissimum in Ken- 
tucky.”?. The specimen is Muhlenbergia schrebert Gmel. 1791 (Mf. diffusa Willd. 1797). 
Aristida dichotoma Michx. 
“Tn Carolina septentrionali juxta Lincoln.’? The specimen belongs to this species 
as described in our manuals. Lower glume 5 to 6 mm., upper glume 6 to 7 mm. long, 
slightly scabrous on keel and sides, the midnerve extended intoa very short awn 0.3 mm. 
long; lemma sparsely appressed-pubescent, 3-nerved, 5 mm, long to base of awns; 
central awn 4mm. long, curved at base to form a half coil, lateral awns erect, | mm. 
long. 
Aristida stricta Michx. 
“Tn Carolina [sign for perennial].’”’ The specimen belongs to this species as de- 
scribed in our manuals. Glumes glabrous, 1-nerved or the lower obscurely 3-nerved 
at base, the lower 9 mm., the upper 11 mm. long, each extended into an awn about 
2 mm. long; lemma glabrous or somewhat hispid below the awns, about 8 mm. long; 
awns about equal, spreading, 1.5 to 2 cm. long. 
Aristida oligantha Michx. 
“Tn apricis pratensibus regionis Illinoensium. Route des Illinois au fort Mossac 
lieux alternativement submergés.’’ The specimen belongs to this species as described 
in our manuals. A scant specimen with afew spikelets. Lemma 1.5 cm. long; awns 
spreading, about 3.5 cm. long, nearly equal, all of them more or less curved or loosely 
coiled at base. On the same sheet is mounted a specimen of Sporobolus, apparently 
S. vaginaeflorus (Torr.) Wood. 
@All the species credited to Michaux were published as new species in his Flora 
Boreali-Americana, 1803, It is well known that this work was edited by L. C. Richard, 
for which reason many authors credit the new species to “ Richard in Michaux.’ 
bThespecimens mentioned under the new speciesare types unless otherwise indicated.
