4 MISSOURI BOTANICAL GARDEN BULLETIN: 
past season about 75 varieties, comprising over 4000 plants, 
have been established. 
A variety nut orchard was established last fall. Some of 
the best varieties of pecans, black walnuts, Persian walnuts, 
and hickories have already been planted, and it is expected 
that an opportunity will be afforded to test systematically all 
varieties of native and imported nuts which are hardy in this 
region. In addition, there are being collected samples of all 
nuts that can be grown here and elsewhere, in order that defi- 
nite information may be available at all times as to the nature 
of the products from various trees and their value for com- 
mercial purposes. 
Very considerable additions have been made to the iris 
collection and the hardy perennials on the knolls. The pools 
in front of the Linnean house, formerly devoted to water- 
lilies, are now stocked with all the best varieties of lotus. 
The difficulties of growing evergreens out of doors at the 
Garden has made it highly desirable that a collection of these 
plants be established under glass, and with the remodeling 
of the Linnean house it for the first time became possible. 
There have accordingly been established here about 130 
species of conifers, together with some of the more rare 
rhododendrons, azaleas, ericas, and other members of the 
heath family. 
The southern half of the greenhouse leading from the 
banana pit (formerly known as the varied industries house) 
has been replanted and is now devoted to a collection of trop- 
ieal fruits. It is hoped that within a few years the trees will 
become sufficiently well established to afford an opportunity 
for the visitor to view these unusual and interesting plants in 
both fruit and flower. Many of the standard commercial 
varieties of orange, lemon, lime, pummelo, kumquat, and 
other citrus plants are to be found here, and in addition some 
of the more recently introduced fruits, such as the litehi, 
avocado, jujube, pineapple guava, ete., are being established. 
Aquaria and Collection of Fish—The aleoves of the aroid 
house, formerly devoted to the exhibition of orchids, have 
been adapted for a display of fancy fish. Some 35 aquaria, 
with an appropriate setting, have been established here, and, 
through the codperation of the St. Louis Aquarium Society, 
a most interesting lot of fish—mostly tropical—are now on 
display. An opportunity is likewise afforded of including 
practically all of the aquatic plants suitable for aquaria, and
