On the Different Views hitherto Proposed 



regarding the Morphology of the 



Flowers of Ginkgo biloba, L. 



{Preliminary note.) 



By 

 Eenjiro Fujii, Rigakushi. 



With pi. i. 



{Continued from No. 108, p. 8.) 



• Provisional diagnosis of Ginkgo: — a deciduous tree, with " Lang- 

 triebe " and " Kurztriebe " ; foliage leaves fan-shaped, dichotomously 

 veined, with the upper margin wavy, usually bilobed, sometimes many- 

 lobed in young trees, entire in flowering branches. Flowers fl) dioecious, 

 single, in the axil of the uppermost scaly leaves and the lowermost 

 foliage leaves ; male flowers in the form of a loose, elongated, short 

 stalked spike ; stamens w T ith two pollensacs and a very small round 

 terminal-scale (" Endschuppen ") ; female flowers long-stalked, usually 

 with two ovules placed opposite to each other near the apex of the 

 stalk ; ovules with a single integument and a 2-lipped micropyle, 

 partially enclosed at the base in a small cup-shaped swelling, usually 

 one ovule only in each flower becoming ripe seed ; seeds drupe-like, 

 the stony part 2-angled. 



W whether what I designate here as a flower is really a single flower or an inflorescence, 

 will be fully considered afterwards.
