18 MISSOURI BOTANICAL GARDEN BULLETIN 
HERBARIUM 
During the year certain improvements have been made 
in the herbarium, notably the installation of several wall 
cases of steel construction which conform with those already 
in use. These additional cases now fully equip the second 
floor herbarium-room with metal cases and give adequate 
protection to the specimens against the possibility of damage 
by fire or dust, to which they are always more or less subject 
in the ordinary wooden case. These cases, moreover, furnish 
the space needed for expansion in this part of the herbarium. 
Quarters have been provided in the gallery of the museum 
building for the parasitic and fleshy fungi; and these groups 
are now being critically studied and thoroughly organized 
by Dr. Burt. The transfer renders available several cases on 
the third floor of the main building and will give oppor- 
tunity to relieve the crowded conditions among some of the 
families of the seed plants. These changes have involved a 
shift of a large part of the collection, but they provide the 
necessary room for interpolation of new material during the 
coming year. Rooms for storage of unorganized and dupli- 
cate material, for sorting and mounting of specimens, have 
been furnished in the old residence. 
New Accessions—The most important accession to the 
herbarium during the past year is the acquisition by pur- 
chase of the private herbarium of Mr. Ernest J. Palmer. It 
contains upwards of 5,000 specimens, about nine-tenths of 
which are from Jasper County, Missouri, and the balance 
are mainly from neighboring counties in the southwestern 
part of the State. The collection represents the botanical 
work of Mr. Palmer during the twelve years from 1901 to 
1913. Special sets of exsiccata, illustrating the flora of dif- 
ferent parts of the world, have been purchased ; several valu- 
able series of plants have been secured by exchange; a num- 
ber of collections have been obtained by gift; and a rela- 
tively large amount of valuable material has been acquired 
through field work. The more noteworthy accessions are the 
following: A. Alexander, plants of Michigan; Arnold Arbo- 
retum, ligneous plants of North America; J. C. Arthur, 
fungi from Mexico and Central America; E. Bartholomew, 
“North American Uredinales,’ centuries IX, X, and XI, 
Nos. 801-1100, and Bre Columbiani,” centuries XLIT 
XLIV, and XLV, Nos. 4201-4500; H. H. Bartlett, plants of 
the Southern States; W. E. Broadway, plants of Tobago, 
W.1.; B. F. Bush, plants of Missouri; J. R. Churchill, plants 
of Colorado and Massachusetts; I. W. Clokey, plants of 
Canada and Illinois; F. S. Collins, “Phycotheca Boreali-
