THIS strange group is limited to a single family, Ginkgoacese, the latter moreover consisting of a single genus, Omkgo, with one species, G. hilohn, the ginkgo or maidenhair tree of China and elapan. Though formerly of rare occurrence in cultivation here, the tree is now frequently used to shade parkways and avenues, though it is not hardy in a severe climate. It is of conical outline, very symmetrical, with thick, slender-petioled irregularly fan- shaped leaves, often more or less lobed or incised at the broad outer margin, and wedge-shaped at the base. The plants are dioecious, separate individ- uals bearing the male and female in- florescences; a spray of leaves with the staminate flowers is shown in Fig. 4. The fruit is bright yellow in color, similar in appearance to a cherry, and fleshy in texture, with a hard central seed of stone:it is also distinguished for its nauseating odor.
