BOTANY. 
Some Botanical Collections. —That most valuable distribution, 
Ellis and Everhart’s “ North American Fungi” has recently com- 
pleted its thirty-second century, carrying the total number of specimens 
up to 3200. On looking over the alphabetical index one notes espe- 
cially that this century includes of Cercospora, 8 species; Cylindrospor- 
ium, 3; Gleosporium, 3; Microsphera, 2; Phyllosticta, 5; Puecinia, 
5; Septoria, 6; Uredo, 3; Uromyces, 2; Ustilago, 1. 
The uniform, and well-known excellence of the specimens in this dis- 
tribution, needs no further words of commendation here. Those who 
can not obtain this set should hasten to secure the second edition 
which bears the name of “ Fungi Columbiani.” 
F. S. Collins, Isaac Holden and W. A. Setchell propose soon to 
begin the publication of North American alge under the title of 
“ Phycotheca Boreali-Americana.” The first fascicle of 50 speci- 
mens will contain species of Oscilliaria, Lyngbya, Calothriz, Monos- 
troma, Ulothriz, Drapanaldia, Rhizoclonium, Caulerpa, Lemanea, 
Chondria, Polysiphonia, Microcladia, ete. It is intended “ to include 
all families of alg, both fresh-water and marine, except that no pro- 
vision has yet been made for diatoms, desmids or charads,” but the 
authors state that these “may be included later.” This work will 
be truly North American, including the whole continent and its 
adjacent seas from the Arctic Ocean to the Isthmus of Panama, 
and the West India Islands. The low price (five dollars per fascicle) 
places it within reach of every college botanical department. Those 
interested should apply to Frank S. Collins, Malden, Mass. 
Josephine E. Tilden of the University of Minnesota has begun the 
distribution of the fresh-water alge of the upper Mississippi Valley. 
It will be important as supplying for the first time a series of these 
plants from a new region. For century I the price is ten dollars. 
The Flora of Amador, Calaveras and Alpine counties, California, is 
offered to the public in sets of prepared specimens at seven dollars per 
hundred by George Hansen of the Experiment Station at Jackson, 
California. The sets are said to contain many varieties and novelties. 
Professor F. L. Harvey, of Orono, Me. proposes to issue sets of the 
Weeds and Forage Plants of Maine, embracing about 300 species. 
They are intended especially for the use of schools and “ granges ”, and 
are sent out mounted and labeled. The moderate price (ten dollars per
