method in which the unmounted collections are arranged and 
temporarily stored in small rooms behind the great Herbarium 
provides for their ready consultation, even before they are 
incorporated into the Herbarium itself. 
The student receives assistance in his investigations from the Library,

of plates and drawings of plants systematically arranged in the 
same order as the plants in the Herbarium. 
The collection of original drawings comprises specimens of Original ^
