lowed was based on the Engler and Prantl system. An unusual 
feature in carrying out the plan was the inclusion of trees and 
shrubs together with the herbaceous plants in the families to which 
they belonged. Further, in certain families, the highly specialized 
horticultural groups are usually planted in the same general area. 
Thus, the display of chrysanthemums is nearby the family of the 
composites. 
At present, the Garden has a collection of more than 300 species 
of trees, representing about 100 genera. There is a total of 275 
genera of shrubs, including about 1,000 species. There are also 
approximately 1,000 species of herbaceous plants. The horti- 
cultural varieties, however, of trees, shrubs, and herbaceous plants. 
greatly increase the total number of different kinds found growing 
in the Garden and add very great interest to the plantations.

In the course of the season there are many special displays of 
ornamental plants. In the early spring, the daffodils, naturalized 
on Boulder Hill and elsewhere, make a fine display. About the

and the crab apples. Doubtless, the most noted feature of the 
Garden is the floral display along Cherry Walk. There, well- 
grown and mature trees of the variety Kwanzan attract thousands 
of visitors for a week to ten days. Nearby are other varieties. 
Not far away are numerous crab apples, which add to the beauty 
of the scene. In the coming years, a new planting of seventy-six 
trees of the same variety, made in 1941, should make an attractive 
display. 
Then follow, in succession, the blooming periods of the lilacs 
and wisterias, the azaleas, peonies and iris, spireas and viburnums. 
In late May come the roses. In the summer, the most attractive 
displays are the waterlilies in the pools in front of the Conserva- 
tories. There are fine collections of both hardy and tropical va- 
rielies and, in the adjacent border, are plantings of many va- 
rieties of annuals. It may be mentioned that the water-lily pools 
were the last gift of Mr. Alfred T. White to the Garden. 
In late July and August, in the Garden lake, the East Indian 
lotus, with its huge flowers, makes a unique display. This plant-
