the stamens are reflexed, so that they protrude between the petals, 
backward almost to the flower-stalk. 
1 consider it remarkable that my brother, while collecting for me 
two years since, found Rubus odoratus, L., well established in swamps, 
in Dade Co., S. Fla ! The specimens sent me seemed to be rather 
depauperate, and the clammy hairs disposed to be stiff. 
At the same place he found magnificent specimens of Cephalan- 
thus occidentalis, with leaves over six inches long, without the peti- 
oles, glabrous and shining, margins reticulate.

We may add to this list Oldenlandia glomerata. Mchx. Mr. A. 
Brown found a patch at Rockaway last September. 
§ 228. Lygodium palmatum in Tennessee.—Prof. Eaton in 
Ferns of America, No, 1, says this species “ occurs, how profusely is 
not known, in Virginia, Kentucky, Tennessee, the Carolinas, Geor- 
gia, and probably in Alabama.” . 
The question of its profusion in one locality in Tennessee is set- 
tled by the discovery, by Prof. A. G. Weatherby of the Cincinnati 
University, of large patches of this beautiful species on the line of 
the Cincinnati Southern Rail Road, a few miles north of Chitwood, 
Scott county. Prof. W. says that there are “literally acres of it;” and 
the specimens brought from the locality are large and fine.

§.229. Publications.—1. Smithsonian Miscellaneous Collections, 
258. Biographical Index to North American Botany, or Citations of 
Authorities for all the recorded indigenous and naturalized species of the 
Flora of North America, with a chronological arrangement of the 
synonomy, by Sereno Watson, Part I. PoLtypeTaLar. Washington, 
March, 1878. Probably no single work ofso great interest to American 
botanists has appeared since the publication of Torrey & Gray’s 
Flora. Itisa work of vast labor and critical research which could only 
have been accomplished with the aid of the rich resources of Cam- 
bridge, and that it is carefully done both the name of the author assures 
us, and we find from consulting the pages for the species which we 
have more particularly studied, The (senera Plantarum of Bentham 
& Hooker has been followed in the sequence of the orders, except- 
ing Paronychieae, while the genera and species are arranged alpha- 
' betically for greater facility of reference. The present part includes 
69 orders, the last being Cornaceae; 545 genera; and 3038 species. 
This gives a little less than 8 genera for an order, and a little more 
than 54 species for a: genus. From Bentham & Hooker for the same 
orders, we estimate about 354 genera to the order, and about 12 
species to the genus for the whole world as far as known. On this 
estimate the North American flora represents about 10 per cent. of 
the species, and 224 per cent. of the genera of these orders ; or, in 
other words, is more than twice as rich in genera as in species. 
A work of this nature must always remain incomplete, owing to 
the multiplicity of publications, the difficulties of synonomy, and the 
necessary delays in publication. To the 442 pages in the body of 
the work are added 25 of additions and corrections, of which it is a 
noticeable trait that a very considerable proportion of the omissions
