care of government, Paris maintains her rank as the chief 
centre of knowledge, not less in Botany than in other 
sciences, In the autumn of last year appeared Gaudichaud's 
Organogénie, and the elaborate treatise of Decaisne on the 
Hydrophytes, containing many new views as to their organi- 
zation. Dr. Montagne finished his two long and exceedingly 
important works on the cellular plants of Cuba and of the 
Canaries. M. de Jussieu presented to the world the Synopsis 
of his forthcoming Monograph of the Malpighiacee, and 
M. Spach published a new volume of his “ Plantes Phanéro- 
games,” in the Suites d Buffon. 
* The harvest of this year promises to be still more abun- 
dant. M. de St. Hilaire lately returned from his journey 
through Norway, from Christiania to Drontheim, and is now 
preparing his Brazilian plants for publication, in the shape of 
a reduced Flora or Synopsis. M. de Jussieu is printing his 
splendid Monograph of the Malpighiacee. Count Jaubert, 
lately a minister of state, in conjunction with M. Spach, is 
at work on a quarto volume, with figures of the plants of 
Asia Minor, collected by himself in his journey through 
that country, to be entitled [lustrationes Plantarum Orien-

intricate genus Erysimum, of which he has just given to the 
world Erysimorum quorumdam Diagnoses ;* a small pam- 
phlet, containing 27 new or revised species of the genus, and 
an exceedingly detailed account of Erysimum murale (Des 
font.), the forerunner, as he promises, of a Monogr aph of 
the whole group. M. Gaudichaud is publishing the plants of 
his last voyage round the world in the Bonite ; several plates 
beautifully illustrated, have already appeared. The indefa- 
tigable Dr. Montagne has commenced the description of the 
cellular plants of the expedition of Admiral d'Urville. The 
first volume, containing a part of the narrative of this im-

those only destined for private distribution, we are sure that we § 
render a service to Botany by giving the same in our Journal, which We 
have the author's permission to do.—Ep.
