 which were placed in the morphological laboratory near the 

 herbarium room. To these cases the lichens, hepatics and

 six cases in the large herbarium room. The space thus 

 gained temporarily and partially relieved the congestion of 

 specimens in the cases. 



(a) Garden Herbarium. A total of 65,006 specimens 

 have been accessioned for the Garden herbarium. All the 

 desirable current distributions of herbarium specimens have

 have been greatly strengthened by the addition of specimens 

 procured on the several exploring trips directly or indirectly 

 under the auspices of the Garden. 



About 71,896 sheets were mounted and incorporated in the 

 Garden herbarium. These sheets contain nearly 80,000 

 specimens. Additions have been made to the local her-

(b) Columbia Herbarium. Herbarium specimens aggre-
