Avena palustris Michx. 



"Georgia Lieux humides." The specimen is Sphenopholis palustris (Michx.) 

 Scribn. ( Trisetum palustre (Michx.) Torr.).° 



Avena striata Michx. 



"A sinu Hudsonis ad Lacus Mistassins," "Lac des Cygnes, Montagn. ent. la Baye 

 de Hudson et le Canada Mistassins." The specimen belongs to this species as gen- 

 erally understood. It is, however, a Melica and would be, according to the Vienna 

 Code, if. striata (Michx.) Hitched By the American Code this name is invalidated 

 by Avena striata Lam. 1783. and must be changed to Melica purpurascens (Torr.) 

 i Trisetum purpurascens Torr. Fl. U. S. 1: 127. 1823; Avena striata Michx., not Lam.). 



Arundo canadensis Michx. 



"A Sinu Hudsonis ad Canadam praesertim ad ripas lacuum [sign for perennial]." 

 The specimen is < 'alamagrostis canadensis (Michx.) Beauv. as described in our manuals. 



Arundo arenaria L. 



"Ad ripas tluminis S. Laurentii a mare affluvienti inundatus." The specimen is 

 Aminophila armaria i L. ) Link. 



Arundinaria macrosperma Michx. 



"Gramen altissimum ramosum a Virginia ad Floridam & in occidentalibus juxta 

 fluviis al> Illinoensibus ad ostium Misissipi [sign for undershrub]." The specimen 

 is fragmentary and one can not be certain which species of Arundinaria it represents. 

 Michaux probably included the large and small canes in one species. As he described 

 t lie plants as being very high, we may retain this names for the tall cane, as is done in 

 our manuals. 



Zizania miliacea Michx. 



There is no sheel bearing this name, but the plant described by Michaux bears the 

 label "Zizania palustris," without locality. It is Zizaniopsis miliacea (Michx.) DoeU 

 & Archers as described in Small's Flora. 



Zizania clavulosa Michx. 



This name does not appear upon any sheet, but a corresponding specimen, answer- 

 ing to the description, is marked Zi:aniu af/uaticu, " Lac Champlain New Jersey Caro- 

 lines Illinois & Lac d'Am." It is Zizania palustris L., the large, broad-leaved form. 



Zizania fluitans Michx. 



" In stagnantibus Carolinae Georgiae el alibi copiosissime juxta Charleston." The 

 specimen is Hydrochloa carolinensis Beauv. (H. fluitans (Michx.) Nash.) Michaux's 

 specific name can not be taken up on account of the earlier II. fluitans Hartm. 

 Michaux's published locality, "ad lacum Champlain," must be an error, for the plant 

 is not known to occur in the north. 



Manisuris g-ranularis Sw. 



"In Carolina." The specimen is Ilackelochloa granulans (L.) Kuntze.
