ZIZYPHUS Tournefort 
ZIZYPH US JUJUBA (Linn.) Lam. Encycl. 3 (1789) 319; Safford 403. 
Rhamnus jujuba Linn. Sp. PI. (1753) 194. 
G. E. S. 1 65, locally known as manzanita. 
An introduced species in Guam; widely distributed in Tropical Asia and 
in Malaya, chiefly in cultivation. 
Mr. Skeels ” has recently proposed to take up the name Zizyphus mau- 
ritiana Lam. for this species, claiming that Zizyphus jujuba Lam. is in- 
validated by Zizyphus jujuba Mill. (1768), a matter that I am unable to 
check on account of lack of literature.
