with only in a cultivated state, having been introduced into 
Europe in 1754; he alludes to the variety variegata , and

Japonica’ 1 includes a description of Ginkgo , accompanied by 
a plate; the author speaks of the tree as native in Northern 
China, but not in Japan—‘ubi praeterlapsis saeculis adnexam

In the more recent botanical literature we find frequent 
references to Ginkgo , dealing more especially with its ana¬ 
tomical structure and with the morphology of the female 
flower.

Diagnosis. 
A tree of pyramidal form reaching a height of over thirty 
metres, with a smooth grey bark ; comparatively hardy 2 , 
and not readily killed by cold or by a smoky atmosphere; 
characterized among existing Gymnosperms by its flat broad 
leaves, deciduous in the autumn, consisting of a long and 
slender petiole slightly grooved on the upper surface and 
a lamina with venation of the Cyclopteridis type, varying con¬ 
siderably in size and shape, occasionally fan-shaped and entire, 
but more frequently divided into two halves by a more or less 
deep median division, or subdivided into several wedge-shaped 
lobes. The foliage leaves occur either scattered on long 
shoots or crowded at the apex of short shoots ; the latter form 
of leaf-bearing axis often passes by apical growth into the
