Cirma arundinacea L. 



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- praesertim in borealibus Canada 

 juxta lacus." A second label, which probably goes with the panicle, reads: "China 

 de Linneus. China envoye par Linn, a Jussieu qui lui avait ete apporte de Canada 

 par Kalni." 



Anthoxanthum odoratum L. 



"In 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. oryzoides, but without 

 locality. It is to be noted that Michaux gives L. virginica as a synonym of L. oryzoides. 

 By priority of Homalocenchrus Mieg. the name becomes H. oryzoides (L.) Poll. 



Leersia lenticularis Michx. 



"In paludosis regionis Illinoensibus [sign for annual]." 



The specimen & belongs to this species, i. e., Homalocenchrus lenticularis i Michx.) 

 Scribn. 



Dilepyrum aristosum Michx. 



No Bpecimen of this could !><■ found. It is, according to description and tradition, 

 Brachyelytrum erectum (Schreb.) Beauv. and is the type of the form known as B. 

 aristatum Etoem. & Schult. and Muhleribergia aristata Pers., though the specific name 

 is altered. 



Dilepyrum minutiflorum Michx. 



"In apricis, pratis Kentucky, IUinoensium pabulum praestantissimum in Ken- 

 tucky.'' The specimen is Muhleribergia schreberi Gmel. 1791 ( M. diffusa Willd. 1797). 



Aristida dichotoma Michx. 



"In Carolina Beptentrionali juxta Lincoln." The specimen belongs to this species 

 as described in our manuals. Lower glume 5 to 6 mm., upper glume <i to 7 mm. long, 

 slightly seal irons on keel and sides, the niidnerve extended into a very short awn 0.3 mm. 

 long; lemma sparsely appressed-pubescent, 3-nerved, 5 mm. long to base of awns; 

 central awn 4 nun. long, curved at base to form a half coil, lateral awns erect, 1 mm. 

 long. 



^ Aristida stricta Michx. 

 y(f "In Carolina [sign for perennial]." The specimen belongs to this species as de- 

 ' ~fl 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 nun. 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. 



"In apricis pratensibus regionis IUinoensium. Route des Illinois au fort Mossac 

 lieux alternativement submerges." The specimen belongs to this species as described 

 in our manuals. A scant specimen with a few 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. vaginaefiorus (Torr.) Wood. 



a 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. " 



&The specimens mentioned under the new species are types unless otherwise indicated .
