was afterwards merged in a prior one, called Desmanthus ; and a 
second Darlingtonia was established, on a rare and remarkable Cal- 
ifornia Plant, by Prof. Torrey, in 1850. 
4. The Genus Townsendia was named by Sir Win. J. Hooker, 
in 1833, in compliment to David Townsend, Esq., of Coventry 
township, (now of West Chester),-an industrious and successful in- 
vestigator of the Botany of Chester county, who by the number of 
specimens furnished, and the elegance of their preparation, has 
done much toward supplying the botanists of Europe with the 
means of studying our vegetable productions. 
5. A species of Lichen, viz: Biatora Micheneri was named by 
the distinguished cryptogamist, E. Tuckerman, A, M., in 1853, in 
compliment to Ezra Michener, M.D., of New Garden township ; an 
indefatigable and accomplished naturalist, who is now success- 
fully investigating the more obscure and difficult families of our 
Chester county plants. 
So much for Chester county. Our state has produced the fol- 
lowing Botanists, in addition, who have been honored in the same 
way, viz: John Bartram, Rev. Henry Muhlenberg, Doctor Thomas 
Horsefield, Prof. B. 8. Barton, Zaccheus Collins, Esq., Prof. Casper 
Wistar, Rev. Lewis D. von Schweinitz; and Major John Adlum. 
On the whole Pennsylvania seems to have done pretty well, in the 
botanical line, compared with her Sister Republics, 
§ 42. Publications—7he American Journal of Science and Art, 
for July and August, contains a critical notice of M. ©. Cooke’s 
Fungi ; their Nature and Uses ; a note on stivation in Asimina, 
concluding that the valvate passes by gradation into the imbricate, 
and cannot serve, as Hooker and Bentham use it, to distinguish 
tribes. Prof. Goodale has a commendatory notice of the English 
translation of Sach’s excellent Text-book of Botany ; Morphologicat 
and Physiological, Mr. Henry Willey gives some account of the 
present state of the controversy about the Schwendener theory, viz.:_ 
that Lichens are compounded of Fungi and Alge. Of the other 
notes the one that interests us most is the announcement that Mr. A. 
Commons has discovered a new locality for Gaylussacia brachycera, 
Gray, “one of the rarest of North American plants.” He found it 
on the banks of Indian River, in Sussex Co., Del., * on the edge of 
a pine forest, growing under the shade of Kalmia latifolia.—2. The 
American Naturalist for the same months has a sharp criticism of 
the theory propounded in the May No. in relation to Embryonie 
Development in Animals and Plants. Mr. Charles Wright seems 
to have found Coreopsis discoidea, Torr. and Gray, spontaneous in 
Connecticut. We are glad to sce the republication of Carruther’s 
useful article on Ergot Dr. Gray describes a variety of 
Botrychium simplex trom Syracuse, communicated by Mr. E. W. 
Munday, and also by Mrs. Styles M. Rust. He calls the variety, 
bipinnatifidum. Mr. C.F. Wheeler, who has observed the dimorphism 
of Menyanthes, finds the fact mentioned in the Botanische Zeitung, 
1867, so that the observation, Butt., 1871, p- 26, was anticipated, 
There are other papers of botanical interest in the Naturalist.—3.
