A WILD CHINESE GRAPEVINE (VITIS DAVIDII).

A species sometimes cultivated in the warm, moist climate of the Yangtze Valley for its small, sour
berries, which make excellent jelly.  Its leaves and shoots are covered with weak prickles, and
the plant appears to be peculiarly free from disease.  Promising for hybridization. Photographed (P569FS-C) at the Chico Field Station, September, 1915.
