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-
