Brooklyn, the design being based on the head of a Catfish or Bull- 
head, whose body is imagined to extend back into the water in 
the bowl. 
From the Conservatory Garden one may retrace his steps to the 
main entrance of the Laboratory Building and proceed westward

SYSTEMATIC SECTION 
Hhat the Systematic Section Aims to Show 
1. Different kinds of seed bearing plants. 
2. The relationship of plants. 
3. How the plants of a given group may be used in decorative 
planting (e.g., for hedges, massing, herbaceous borders, 
ground cover, etc.). 
4. Horticultural varieties derived from wild species by plant 
breeding. 
Most of the plants in the Systematic Section are not included 
in the Local Flora area, as defined on page 170, but a few Local 
Flora plants are included in groups not otherwise represented, 
PLANTING PLAN 
In the Systematic Section plants are grouped according to 
families. For example, the various plants of the buttercup family 
are in one place. The plan is approximately that of the Engler 
system. It is believed that plant groups are related to each other 
like the branches of a tree, but the exact relation of families and 
orders is often debatable. A botanic garden, once planted, can- 
not easily be changed; trees and shrubs, in particular, cannot be 
moved with constantly changing ideas as to classification. The 
planting of the Systematic Section of the Brooklyn Botanic Garden 
was begun in 1914, 
The seed-bearing plants that have no “ flowers” (Gymno- 
sperms) are found north of the wall which leads fron. Magnolia 
Triangle to the Ginkgo Triangle, and are chiefly east of the Brook 
in the area which includes Boulder Hill, and beyond.
