1889. | NEW YORK ACADEMY OF SCIENCES. 61 
IV. Marcu 25tTH.—The Little Builders of the Earth. 
Rev. E. C. Boies, of New York. 
VY. Aprit 15TH.—Glacial Moraines in the Front Range, Col. 
Mr. Freperick H. Cuapin, of Hartford. 
Dr. N. L. Brirron then described a collection of plants made 
by Dr. E. A. MEARNS in Arizona, illustrating it with a large 
and interesting series of mounted specimens. 
Dr. Henry H. Russy followed with a description of the bo- 
tanical characters of the region whence Dr. Mearns’ collection 
was obtained; these two papers, constituting the programme 
for the evening, were as follows: 
A LIST OF PLANTS COLLECTED AT FORT VERDE AND VICINITY AND 
IN THE MOGOLLON AND SAN FRANCISCO MOUNTAINS, ARI- 
ZONA, 1884-1888, BY DR. E. A. MEARNS, U.S. A. 
(With description of new species. ) 
BY N. L. BRITTON. 
The collections here enumerated were sent by Dr. Mearns to 
the American Museum of Natural History, and were thence re- 
ferred to me for determination by Mr. L. P. Gratacap. A com- 
plete set exists at the Museum, and another nearly complete one 
has been placed in the Herbarium of Columbia College. A few 
duplicates have been distributed. 
It is to be hoped that Dr. Mearns will continue his botanical 
explorations; for in the recesses of the mountains of this portion 
of Arizona there doubtless occur other species and varieties as 
yet unknown to science. It is not likely that the following list 
contains the names of more than one-third of the plants which 
are to be found in the district. Dr. Rusby’s account of the gen- 
eral floral features of the country, written from studies made by 
him in 1881-1882, at the time he made his very extensive gather- 
ings which contain so much that is novel and interesting, wil 
forcibly supplement my bare cataloguing of the species. 
RANUNCULACE. 
Anemone cylindrica, Gray. Baker’s Butte (51). 
Anemone decapetala, L. San Francisco Mts. (15).
