Breslau, 1 . 286, 8vo.— While awaiting the oe of the 
neral atsbeodethte of the order, contributed by Dr, Andersson to the 
rodromus, and of the Jcones Salicum he has also prepa ared, we receive 
this beautiful volume, in whic ny sian restricting his attention to 
the European Willows, has yovised these with much detail and oe 
which different sce have pr opos . Dr. Wimmer himself arranges 
the Willows of Europe under eleven tersely characterized tribes, each com- 
prising from one to six - gar e admits only 31 to the rank of genu- 
ine species, reducing a mber to mere synonyms, and having well 
characterized these in ‘ee. hs half of his volume, he devotes the rest to 
Salices hybride. These hybrids, 57 in number, and chief m 
cording to their akon ee are disposed under fourteen wiiaiohe and their 
synonymy is fully indicated. whole work gives the —— of 
being thoroughly reliable and excellent.

1866.—Professor Parlatore’s essay upon the yee question of ‘the 
species of Cotton was called forth by a Royal Italian Commiss —_ and 
is dedicated to its President, Devincenzi. The Soren s of 6 ges,

the description of the species, with the characters and full synonymy, are 
in Latin, but the farther details in Italian. He describes seven species 
(besides referring to as many doubtful ones): @. arboreum, or Tree Cot- 
4 eum, the common herbaceous Cotton; &. Barbadense, or 
been sini d variously ‘confounded with others; and G. Sandvicense, also as 
ies from the Sandwich Islands; but this has already been 
lished a Dr. Seemann, under Nuttall’s name of G@. tomentosum.
