that the Herbarium of the Department of Agriculture is wanting 
in many things that can only be procured by special effort. On 
motion, the President appointed a committee, consisting of 
Messrs. Thomas Hogg, Jos. Schrenk and N. L. Britton, to draft 
resolutions expressing the desirability of making the Herbarium 
of the Department of Agriculture as complete as possible. 
Dr. Newberry remarked on the relations of Pinus edulis, 
Englm., and P. monophylla, Torr. and Frem., and referred to his ‘ 
former papers on the subject. (See BULLETIN, May, 1885, and 
October, 1886). He exhibited specimens collected: by Marcus 
E. Jones at Lewiston, Utah, which show both the single and 
double needles on the same branch, proving that the species are 
not distinct, and that Sir Joseph Hooker’s view is erroneous. 
(See Gardener's Chronicle, July 31st, 1886). Mr. Jones states 
in a letter accompanying the specimens, that some trees have 
about half the leaves double, and half single. 
Prof. Schrenk exhibited specimens of Halenia deflexa, 
Griseb., from Coshecton, Sullivan Co., N. Y. 
Dr. Rusby remarked on the use of botanical names by phar- 
macists, stating that many are merely trade names, and that there 
is often great difficulty in ascertaining what species is really 
meant. If it were practicable to insist that the author should 
always be cited, much confusion would be avoided. Mr. A. A. 
Crozier spoke of the same difficulty in tracing the names of culti- 
vated, ornamental species. 
Dr. R. E. Kunzé exhibited and distributed blossoms of Cereus 
nycticalus, Link., which were much admired. 
Dr. Britton showed Plantago Patagonica, Jacq., var. aristata, 
Gray, collected by Rev. R. E. Schuh at Rutherford, N. J., where 
it is abundant in one locality. Prof. T. C. Porter stated that it for- 
merly grew on the campus of Lafayette College at Easton, Pa., 
_ but has now disappeared. Mr. E. B. Southwick reported it from 
Riverside Drive, New York Island. Prof. Farlow had seen it at 
_ Wood’s Holl, Mass.; and Prof. Claypole at Akron, Ohio. At 
all these stations it appears to be a mere waif. 
Prof. Porter remarked on the occurrence of Amphiachyris 
_ dracunculoides, Nutt., at Easton, where it was introduced in hay 
from the West, and of Blephilia ciliata, Raf., near the same
