18 MISSOURI BOTANICAL GARDEN BULLETIN 
HERBARIUM 
The herbarium has continued a steady, normal growth dur- 
ing the past year. Although the total number of herbarium 
specimens acquired is not quite as large as it has been in some 
former years, yet the new material is fairly well distributed 
geographically and represents numerous groups of non-vas-- 
cular and vascular plants. Substantial additions to the her- 
barium have been made from the eastern provinces of Can- 
ada, New England, the Piedmont Plateau of southeastern 
United States, Kentucky, Illinois, Missouri, Arkansas, the 
northern Rocky Mountain region, the Pacific coast states, the 
southwestern United States, Mexico and Central America, 
West Indies, northwestern South America, southeastern 
Europe, and China. 
The congested condition of the herbarium has been some- 
what relieved temporarily by the installation of several blocks 
of new steel cases which now accommodate the greater part 
of the monocotyledonous families. Additional case-capacity, 
however, is imperative in order that the rapidly growing col- 
lections may be properly cared for. <A considerable part of 
the curator’s time, as in previous years, has been devoted to 
a more thorough organization of the material on hand, so that 
the specimens may be more readily accessible for reference and 
critical study.

tions which have been added during the year are the follow-
