found growing together by Mr. Drummond: as well as by 
Mr. Townsend near West Chester, Pennsylvania.* 
5. Myosurus minimus, L.—M. Shortü, Ra£.—N, Orl. (n.3.) 
6. Ranunculus Flammula, L.— Ohio. 
7. R. pusillus, Poir.—Pennsylv. N. Orl. (n. 4.) 
8. R. abortivus, L. N. Orl. 1833. 
9. R. recurvatus, Poir.—Alleghanies. Ohio. N. Orl. (n. 5.) 
—fP. minor. Pennsylvania. Much smaller and slenderer. 1 
possess the same var. from Mr. Greene, gathered near 
Charleston, S. Carolina, in which the stems show a disposition 
to become stoloniferous. 
10. R. Aispidus? Mich.—St. Louis.— This specimen is 
too imperfect to enable me to decide upon the species. 
11. R. fascicularis, Muhl.— Pennsylvania.—£. foliis radi- 
calibus ovatis integris.—N. Orl. 1833, (in two states.) 
12. R. muricatus, L.—N. Orl. (n. 6.) Alleghanies. 
(From Dr. Darlington I have received a specimen of Ran. 
trachyspermus, gathered in Virginia, which enables me to deter- 
mine that species to be identical with the R. parviflorus, L. 
I possess the same, without name, from Dr. Torrey, discovered 
by Mr. Le Conte in Georgia.) 
I am indebted to my valued correspondent, Dr. Short of 
Lexington, for most beautiful specimens of the rare Enemion 
triternatum of Rafinesque. It is identical with the European 
Lsopyrum thalictroides, in every thing except the presence o 
petals. But it can neither be separated from that Genus 
nor from that species without violence to nature: so that 
* I am anxious to notice here, a most remarkable state of A. Virgini- 
ana, found at Tewkesbury, by Mr. Greene, smaller in all its parts than 
usual, bearing only one flower arising from a 3-leaved petiolated involucre, 
and having a remarkably elongated and perfectly cylindrical head or carpels. 
lam the more disposed to agree with Mr. Greene in considering it a 
variety of A. Virginiana, because I possess in Gouan's Herbarium, a 
pecimen of which the fruit is more elongated than usual, though much 
less so than in the individual in question.
