Mr. Bolander presented his report, as Curator of Botany, for the year 1865, as follows.

During the past year the Herbarium of the Academy has been increased—

1st. By a set of Hall’s Rocky Mountain Plants.

2d. By a collection of plants from the Western States, made by Mr. Elihu Hall.

3d. By a large collection made by Mr. Canby at Wilmington, Del.

4th. By a small collection from M. S. Bebb, Esq., Washington, D. C.

To the above-mentioned collections, I have added specimens of each plant collected by myself during the past year.

Dr. Kellogg and myself have presented to the Academy quite a number of Australian plants, and both Dr. Kellogg and Mr. Bloomer have assisted me in arranging and classifying our collections.
