pound leaves, or those in which there is a distinct jointing ot 

 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 con- 

 taining 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 selected or 

 placed to the left of this bed and properly labeled. 



A little beyond the pool may be found the bed illustrating 

 flower-clusters, and still further on that devoted to parasitic 

 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 accommodating themselves 

 to their natural surroundings are shown. Further 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 require 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.
