16 MISSOURI BOTANICAL GARDEN BULLETIN 
HERBARIUM 
The herbarium has made marked progress during the year 
in adding to its collections, in more thoroughly organizing 
the material of several groups of families, and in the installa- 
tion of additional cases. A room on the third floor of the 
main building is being equipped with new steel cases which 
will accommodate in adequate manner for several years the 
rapidly growing collection of grasses.

the year has been that of the private herbarium of the late
