Actinidia callosa. Actinidia polygama.

Actinidia callosa Lindl. Ternstroemiaceae. Kokuwa.

Japan and Manchuria. This vine is common in all the valleys of Yesso and extends to central Nippon. It is vigorous in growth and fruits abundantly. The fruit is an oblong, greenish berry about one inch in length; the pulp is of uniform texture, seeds minute and skin thin. When fully ripe it possesses a very delicate flavor.

Actinidia polygama Franch. & Sav.

Northern Japan. This is somewhat less desirable than A. callosa, as it fruits less abundantly and the vine is not so rich in foliage.
