250 e BOTANICAL INFORMATION. 
(Isnardia) palustris, written principally with the view of vindicating 
the generic name of that plant given to it in 1710 by Francis Petit, 
who first constituted it a separate genus. 
M. Barbieri has published the description of a new species of Val- 
lisneria (V. pusilla), which he found near Pavia. 
The first number of the ninth volume of Professor Bertoloni's * Flora 
Italica’ has made its appearance. It contains the remainder of Car- 
duacee, together with those genera of Hupatoriacee, Asteroidee, and 
Senecionidec, distributed in the classes Syngenesia polygamia equalia and 
Syngenesia polygamia superflua of the Linnean system, followed by the 
author. The first genus described is Cnicus, of which alone thirty-one 
species are enumerated ; at this one must not be surprised, considering 
that it is made to include Cirsium, Picnomon, Chamepeuce and Notobasis 
of modern botanists; the author even considers it as only artificially 
separated from Carduus by the character of pappus plumosus. Then 
follow Onopordum, Cynara, Carlina, Atractylis, Acarna (Atractylis can- 
cellata, L.), Kentrophyllum, Carduncellus, Bidens, Adenostylis, Eupato- 
rium, Stehelina, Chryzocoma (including Linosyris), Santolina, Diotis, 
Lonas, Orsina, Bert. in Ann. Sc. Nat. non DC. (O. camphorata, Bert., 
Jasonia glutinosa, Guss. non alior.), Balsamita, Desf., Tanacetum and 
Artemisia. There is little or nothing new as regards the species of Ta- 
nacetum ; not so with the last genus Artemisia, in which we find 4. 
pedemontana, Balb., and A. nitida, Bert., separated from .4. lanata, and 
most of the species accompanied by an elaborate synonymy. 
We have received a cireular addressed by M. Ettore Celi to all 
Italian botanists, informing them of the formation of a public herbarium 
in Modena, under the name of * Reale Erbario Atestino," of which he 
is named the director, and inviting them to exchange specimens of plants 
with the Modena Herbarium. At the end of each yeer he is going to 
publish a catalogue of specimens ready for distribution, and send it to 
all those who ask for it. 
The report on the disease of the vine, by the commission appointed 
by the Accademia dei Georgofili of Florence for that purpose, is now 
printing. As soon as I have obtained a copy I shall not fail to give 
you an abstract of it, with all the details the subject deserves. I am 
sorry to be obliged to add, that during the last few days symptoms of 
the disease have again manifested themselves in some parts of this 
place, as well as in the environs of Pisa, and generally in all flat parts of
