leaves on the stem; and to the left of this are specimens 
illustrating the various ways in which plants may form a 
mosaic covering on the ground. A little beyond are the 
examples of stem-forms; one bed shows the smaller kinds, 
while for the larger examples, illustrating tree-twining, 
root-climbing and tendril-climbing stems, specimens have 
been placed to the left of this. 
A little beyond the pool may be found the bed illustrating 
flower-clusters, and still farther on that devoted to para- 
sitic plants, or those deriving their nourishment from the 
living tissues of other plants. To the left of this and farther 
up the hill is the group of plants showing leaf-positions. 
Beyond and a little to the right are plants which are at 
home in desert regions, and the various means of accom- 
modating themselves to their natural surroundings are 
shown. Farther on to the right is the bed devoted to 
fruit-forms; and to the left of this, one showing various 
forms of seed-dispersal, those with the surface of the fruits 
covered with some sticky substance or curved appendages 
or hooked hairs or spines requiring the intervention of some 
animal for their distribution, while those with wings or 
with hairs attached to the seed are spread through the 
agency of the wind. To the right of the above are plants 
representing a species and a variety, and to the left of this 
is a bed containing plants showing species and hybrids. 
10. Economic Garden 
The collections illustrating food plants and those produc- 
ing substances directly useful to man in the arts, sciences 
and industries are planted at the northern end of the long 
glade containing the herbaceous collections just described. 
The collection is arranged in two series divided by a central 
grass walk. The beds on each side are numbered consecu- 
tively, the number being indicated on a wooden stake in 
the center. A general sign is placed in each of the beds, 
denoting what its contents are intended to represent, and 
in front of each plant is a smaller label giving individual 
information.
