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. 



(c) Economic Garden 



The collections illustrating plants producing substances 

 directly useful to man in the arts, sciences and industries are 

 now being installed at the northern end of the long glade 

 containing the herbaceous collections just described. They 

 illustrate food-plants, fiber-plants, drug-plants, fodder-plants, 

 and a variety of other economic species. 



(d) Viticetum 

 The area devoted to the plantation of vines is at the easterly 

 side of the economic garden. Hardy vines, whether woody 

 or herbaceous, belong here, and a rough arbor has been con- 

 structed for them to climb on. This collection is now being 

 developed, and only a few of the species which it is in- 

 tended eventually to grow there are as yet in place. The 

 families will be referred to below in the order of their 

 sequence. The arrangement begins at the southerly end of 

 the arbor, on the left hand side, with the smilax family, to 

 which belong the green-briers or cat-briers. The yam family 

 is placed immediately opposite to the right, followed by the 

 mulberry family on the same side. The birthwort family, 

 with the dutchman's-pipe as a representative, follows the 

 smilax family on the left ; and opposite to this is placed the
