by Mr. Nuttall, and among other interesting matter, includes 
the following new genera. 
STYPHONIA, an Anacardiaceous tree from California. 
OrzopniLa, a Celastraceous plant, named Llex myrsinites 
by Pursh, and Myginda myrtifolia by Nuttall, DeCandolle, 
and others. 
ASTROPHIA, a Leguminous plant from the Oregon, related 
to Lathyrus and Orobus. 
HomazoBus, a Leguminous genus, composed of several 
herbaceous species, with the habit of Phaca and nearly the 
legumes of Vicia ; to this are referred the Phaca nigrescens of 
Hooker, and Orobus dispar of Nuttall. 
KENTROPHYTA, consisting of two Leguminous plants, from 
the hills of the Platte, allied to the last. 
CHAPMANNIA, another Leguminous plant, related to Stylo- 
santhes on the one hand, and to Arachis on the other, found 
at Tampa bay in East Florida. 
Among other things relating to species, it appears that 
the Ceanothus azureus of our gardens, is not the plant so 
named by Desfontaines, which came from Mexico, but the 
C. thyrsiflorus of Eschscholtz, a Californian species. 
CLIMATE OF BRAZILIAN ORCHIDACE FE. 
Although this is the summer season, the thermometer 
has never been higher than 84° in the shade at noon,—it 
ranges from 68 to 75° and is seldom higher: but after a few 
days continued rain, I have observed it as low as 62%, In the 
winter season it sometimes descends to 32° during the night. 
All the European vegetables grow pretty well, as also several 
fruits, such as the apple, the fig, the grape, the olive, and 
peach. The tea plant thrives well, but it is too cold for the 
orange and the coffee; the plants themselves grow luxuri- 
antly, but their fruits do not come to perfection.” —Eztract 
of a letter to George Wailes, Esq. of Newcastle, from Mr. 
Gardner, dated January, 1837, and written amongst the 
Organ Mountains, at an elevation of 3100 feet. 
* HABITS OF BRAZILIAN PARASITES. 
The destruction of a tree in these woods does not 
lessen the abundance of vegetable life. On every blasted 
stem which had lost its own bark and leaves, a crop of para- 
sites had succeeded, and covered the naked wood with their
