ground on which the White Memorial stands is Boulder Hill, so 
named from the large glacial boulder on its summit. (See Brook- 
lyn Botanic Garden Guide No. 3, The Story of Our Boulders, to 
be published soon.) 
From the site of this Memorial one may view the East In- 
dian Lotus and various kinds of Water Lilies growing in the 
Lake. This forms one of the Water Gardens. 
Conservatory Garden 
A short side trip toward and past the Laboratory Building will 
take one down the steps and through the site of the Formal Garden 
to be developed in front of the Building, thence down a second 
flight of steps to the Conservatory Garden, containing two Water 
Lily Pools. The northern one has heated water and contains only 
tropical forms, including the Victoria regia Trickert. The south- 
ern pool contains the hardy sorts that do not require heated water. 
These two pools were the gift of Mr. Alfred T. White. 
From the Conservatory Garden one may retrace his steps to the 
main entrance of the Laboratory Building and thence proceed west 
(to the left) ; or, if one did not take the side trip to the lily pools, 
he may pass from the White Memorial down the west slope of 
Boulder Hill; or, if one did not pass around the lake, he may con- 
tinue past the Torii and along the west shore of the lake to its 
outlet, coming, in either case, to the beginning of the 
Systematic Section 
What the Systematic Section Aims to Show 
1. Different kinds of plants. 
. The relationship (botanical affinities) of plants. 
3. The sequence of plant Orders. 
Nd 
The sequence here followed is approximately that of the 
Engler System, modified to some extent by horticultural 
and other requirements. Other sequences have been pro- 
posed, and new investigations will, no doubt, result in the 
formation of other probable sequences. 
4. How the plants of a given group may be used in decorative 
planting (c.g., for hedges, massing, herbaceous borders, 
ground cover, etc.). oon
