Plantations 
Classification Revised.—The classification of the plantations, as 
given in the First Annual Report,* has been slightly revised by 
including the arboretum and fruticetum as subdivisions under the 
systematic section, and thus reducing the number of sections from 
ten to eight. 
W ork Done.—The work done on sections I-IV and VI is noted 
in the appended report of the curator of plants. The installation 
of Sections V, VII, and VIII has not yet been begun. 
Method of Accessioning—When a plant of a given species (or 
several specimens of the same species from the same locality) is 
added to the systematic collection of living plants it is assigned an 
accession number, which serves to designate this plant (or plants) 
as long as it remains a part of the systematic collection. If, sub- 
sequently, another specimen (or several specimens) of the same 
species is received, from the same or another locality, it is ac- 
cessioned and designated by another accession number, the next 
unassigned in the series. Thus the number of accession numbers 
assigned may exceed the number of species represented, while the 
number of individual plants is always much larger than the num- 
ber of species. 
Number of Plants under Cultivation.—Attention is here called 
to the statement of the curator of plants (p. 55), showing that 
1347 accession numbers were assigned to living plants during the 
year, giving a total of 3,859 accessions to date. The living plants 
now under cultivation represent 804 genera and 3,105 species. 
This includes only the plants in the Local Flora, and the general — 
systematic section, and in the conservatories.

Library 
Permanent Quarters——The permanent quarters planned for the 
Garden library are in portions of the building not yet constructed. 
For the present the steel stacks and other library equipment have 
been installed in the elementary laboratory (west room) on the 
main floor. 
Growth.—The appended report of the librarian shows a total of 
1,630 bound volumes and approximately 1,100 bound pamphlets, 
while the number of periodicals being received, having to do with 
botany or closely related subjects, is sixty-three.
