Avena palustris Michx. 
“Georgia Lieux humides.’’ The specimen is Sphenopholis palustris (Michx.) 
Seribn. ( 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, M. striata (Michx.) Hitehe.6 By the American Code this name is invalidated 
by Avena striata Lam, 1783, and must be changed to Melica purpurascens (Torr. ) 
(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 Calamagrostis canadensis (Michx.) Beauv. as described in our manuals. 
Arundo arenaria I.. 
“Ad ripas fluminis 8. Laurentii a mare affuvienti inundatus.”’ The specimen is 
Ammophila arenaria (1..) Link. 
Arundinaria macrosperma Michx. 
“Gramen altissimum ramosum a Virginia ad Floridam & in occidentalibus juxta 
fluviis ab Ilinoensibus 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 
the 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 sheet bearing this name, but the plant described by Michaux bears the 
label © Zizania palustris,” without locality. It is Zizaniopsis miliacea (Michx.) Doell 
& Aschers 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 Zizania aquatica, * Lac Champlain New Jersey Caro- 
It is Zizania palustris L., the large, broad-leayed form.

lines Illinois & Lac d’Am. 
Zizania fluitans Michx. 
“In stagnantibus Carolinae Georgiae et alibi copiosissime juxta Charleston.”” The 
specimen is Hydrochloa carolinensis Beauv. (HI. fluitans (Michx.) Nash.) Michaux’s 
specific name can not be taken up on account of the earlier H, Jluitans Hartm. 
Michaux’s published locality, “ad lacum Champlain,’? must be an error, for the plant 
is not known to occur in the north. 
Manisuris granularis Sw. 
“In Carolina.’ The specimen is [/ackelochloa granularis (L.) Kuntze.
