crosses the valley. It is designed to illustrate here with 
typical examples the organs and other features of plants, 
including leaf-forms and the various modifications of their 
margins, their venation and insertion on the stem; also 
the various kinds of stems, methods of propagation, 
flower-clusters and fruits, leaf-movements, parasites, desert 
plants and seed-dispersal. Looking north on this collec- 
tion, the first bed to the right of the brook contains plants 
illustrating simple leaf-forms. Immediately following this 
on the same side of the brook are the plants representing the 
various forms of compound leaves, or those in which there 
is a distinct jointing of the leaflets to the leaf-axis. Farther 
along the brook, in the pool, may be found various forms 
of aquatic roots, stems and leaves; and a little beyond this 
to the right is the bed containing plants illustrating forms 
of propagation. 
The remaining plots of this collection are located on the 
left hand or westerly side of the brook. The first of these 
to the right is devoted to leaf-venation, and the one to the 
left to leaf-margins, the former illustrating the character 
of the veins and nerves, and the latter the toothing or 
lobing of the margins. Beyond this to the right is the 
group of plants showing the manner of insertion of the 
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 is devoted to show 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 bed. 
A little beyond the pool may be found the bed illustrating 
flower-clusters, and still further 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-
