Acer Oliveriaimm PAX. var. microcarpum HAYATA Materials for a

 Flowers unknown. Carpels glabrous, 2.1 cm. long, cells slightly nervose, 

 wings oblong, 2-2-} cm. long, rounded at the apex, narrowed at the base, 

 margin rounded on the exterior side, divaricate at an angle of 110-120.

Differs from the type in having extremely small carpels. I have ex- 

 amined the fruits of the variety and ascertained that although they are extre- 

 mely small, they are quite in mature state, having albumen and embryo. This 

 differs also from the other variety Nakakarai in the shape of wings. In this 

 variety, the wings are usually oblong, while in the other, they are always 

 semi-oblong or cultriformed.

There is at Kew a specimen very much like this. The specimen is 

 labelled "Acer capittipes MAXIM. Japonia, Nippon, Prov. Shiuano, 1864, 

 leg. TSCHONOSKI." The present plant differs from it in having leaves with 

 larger serration, and longer side lobes which are placed in a little upper portion.
