§ 56. Valeriana sylvatica, Richards—Mr. Hoysradt has just 
sent me very complete and beautiful specimens of the Valeriana 
sylvatica he finds at Pine Plains. If, as I take it, the Valeriana 
sylvatica, described by Richardson from Northern British America, 
is the same as the plant of Western New York, Vermont and Mich- 
igan, these specimens are undoubtedly of that species, but of a most 
luxuriant form, with larger flowers as well as foliage and the radi- 
cal leaves almost all toothed, incised, or divided. This is naturally 
associated with the luxuriance of the plant, and that, perhaps, with 
the lower latitude and low elevation in which this species is now 
unexpectedly found. The difficulty I encounter in the limitation of 
this species comes from the Rocky Mountain and more western 
form, with smaller flowers and mostly much simpler leaves, the 
radical ones almost always entire, the whole appearance of the plant 
nearly that of V. dioiea, but the flowers not diccious, or distinctly 
dimorphous, and the stigma nearly entire. My Oke:

[ Mr. Hoysradt writes that he has found still another marsh where 
this plant is very abundant, with the same peculiarities, which at- 
tend the smaller as well as the more luxuriant plants. Of course 
‘< Salix coneddor, Ging.” in his note last month, § 48, was a misprint 
for “ Solea concolor, Ging.”’] 
§ 57. Isaac H. Hall.—This accomplished scholar, having been ap- 
pointed professor of English in the Protestant College at Beirut, 
sailed for Syria about the Ist of September. In London he was 
very kindly received at the British Museum, and had the oppor- 
tunity of comparing notes with Dr. Birch. Mr, Hall will now be 
able to study his favorite Shemitic languages in their home, and 
will be comparatively near to the Cypriote remains in deciphering 
which he has made himself a name; but the Club will miss a valua- 
ble member and the readers of the BuLLetin a welcome contributor. 
We hope, however, to receive communications from him, not only 
out of his store of observations on our own flora, but a'so in reference 
to the vegetation of his new home, where he will find Dr. Post and 
Mr. Wood, both New-Yorkers, to sympathize in his botanical tastes. 
§ 58. Increase A. Lapham.—Dr. Lapham of Wisconsin, a well 
kaown botanist, died at Oconomowe, in that State, on the 13th of
