Herbaria 
The herbarium equipment was not essentially changed 
during the year. As previously stated in regard to the 
museums, the herbarium cases, which were to be available 
earlier in the year, were not finished until the end of 
December. 
The collections comprising the herbaria were increased 
by specimens derived from a very extensive geographic area, 
particularly by the addition of algae, fungi, hepaticae and 
mosses, and flowering plants, from North America. Two 
aaluabe private herbaria came into the possession of the 
Garden, one, that of the late Mr. J. J. Crooke, as your gift, 
the other that of the late Professor A. J. McClatchie. All 
desirable current plant distributions and exsiccatae were 
secured. 
About 48,000 specimens, representing selections from 
collections in storage and from the herbaria referred to in 
the preceding paragraph, as well as the specimens of the 
distributions and exsiccatae also referred to above, were 
mounted on about 32,000 herbarium sheets and were 
incorporated in the permanent collections. Several thou- 
sand bulky specimens of fungi, fruits, and seeds were added 
to the series contained in multiple size boxes. 
he uneven development of the general herbarium neces- 
sitated the shifting of nearly the whole collection once, and 
parts of it several times, during the year. 
The monographic ee in connection with North American 
Flora resulted in materially building up the herbarium, 
especially in the case of those groups of plants upon which 
the current work is directed. Many fragmentary type 
specimens and photographs of type herbarium sheets were 
acquired as a result of the work on this flora. 
An important and desirable feature of the year’s work 
was the mounting, and incorporating in the permanent 
collection, of several years’ accumulation, representing many 
thousands of Philippine Island plants of recent collections.
