Extracts of a letter from Dr. John Torrey 
of New York, to Prof. Bafinesque of 
Philadelphia , March 1832. 
I have lately received some of 
your new plants from Ohio, and also 
from Kentucky, sent by Mr. Eaton. 
Your Cladrastis is certainly the 
Virgilia of Michaux, if must be se- 
parated, from the Exotic Virgilias,and 
your name (of 1825) is a very good 
one. 
Stylypus has interested me very 
much, the stipe changes in appear- 
ance in different periods of inflo- 
rescence. 
Enemion is distinct from Isopy- 
nun ; but the L thalictroides of Ger- 
many may perhaps belong to it. 
Your E . biternatum l suspect to be 
the Thalictrum davellatum of Dec. 
and Delessert Ic. t. 6. collected by 
Michaux; but without seeds; while 
the seeds make this genus. 
24. Description of a new cherry tree from 
the Oregon Mountains. 
I noticed as -early as 1829, in 
Washington Square of Philadelphia, 
affine tree said tp have been brought 
by Lewis and Clarke , from the Ore- 
gon or Rocky Mountains.' I ascer- 
tained that it was a n.sp. and sent an 
account of it to Decandolle in 1 830. 
I call it Prunus (Cerasus ) rotundi- 
folicC. Arborescent, leaves rounded, 
base often subcordate, end obtusely 
acuminate, margin serrulate. Flow- 
ers fasciculate, berries oblong small 
and black. 
Descript. A fine large tree £0 feet 
high in £0 years growth. Bark very 
dark nearly black. Branchlets slen- 
der with a greyish brown bark, buds 
small rufous, with obtuse scales. 
Leaves like those of apricot, but 
much smaller, about one inch long, 
not so smooth, a little rough, but not 
pubescent. Blossoms in May and 
produces a profusion of white flow- 
ers with a fine smell of honey. The 
cherries are ripe in July, small, one 
fourth of an inch long, elliptical, 
looking like small wild plumbs; but 
black, soft and sweet when ripe. 
Good to eat, but if too many are 
eaten causing sickness in the sto- 
mach, like all the wild cherries. 
Stone oblong acute as in plumb, but 
without the 3 keels as in cherry. 
I think that I have seen the same 
tree in West Kentucky in hills; but 
I did not see the fruit there. It may 
be found from Kentucky to Oregon; 
It is now naturalized in Pennsylva- 
nia, and may probably be improved 
by grafting. Birds and children are 
fond of the fruit. C. S. R. 
25. Account of 2 N. Sp. of Dionea or 
Venus fly trap. 
This beautful genus was supposed 
to consist of a single sp.; but out of 
many plants brought from Carolina 
and Florida to our Philadelphia gar- 
deners, I have detected £ new ones 
D. sessiiiflora and 1). uniflora . 
These are their respective charac- 
ters. 
1. Dionea muscipula L. Petioles 
cuneate broadly obcordate at the 
end ; flowers corymbose, 4 to 9 on 
long peduncles, bracts linear. 
£. Dionea sessiiiflora, Raf. 1830. 
Petioles winged, oblong or subcu- 
neate narrow, ' acute at both ends; 
flowers sessile, 3 to 5 aggregate, 
bracts lanceolate. Observed In the 
Botanical Garden of Maparran in 
blossom in May 1830. The true 
leaves are bilobe and ciliate as in 
the first, they also catch flies. Scape 
terete elongate, flowers white with 
short concave bracts. Division^ of 
the calyx lanceolate 1 , acute, Capsules
