THE CHINESE J QJUBE. 7 
This, the so-called Indian jujube, has usually passed under the 
name of Ziziphus jujuba, but that name should be retained for the 
Chinese jujube, which in the past has generally been called Ziziphus 
vulgaris and Z. sativa. The Indian jujube is native to British 
India, southwestern China, and perhaps also to parts of the Malay 
Peninsula. There are three Sanskrit names for it, and its cultiva- 
tion in India dates from ancient times. It has now been introduced 
into the East Indies, Australia, and the Mediterranean region. In 
Fig. 3. — Ziziphus lycioides. This American relative of the jujube is found in semi- 
arid situations in the southwestern United States. The long thorns, which are modi- 
tied branches, have lateral branches bearing leaves and flowers. The thorns in 
Z. jujuba are stipular in origin ; hence do not produce brandies. 
Egypt it is called 'ennab. On the island of Mauritius a large num- 
ber of horticultural varieties have been evolved. The species toler- 
ates even a warmer climate than does the Chinese jujube. The fruit 
is quite acid in flavor and should prove of value as a tart fruit in 
the warmer sections of Florida. It has been introduced by the De- 
partment of Agriculture into southern Florida, where there are a 
number of trees in bearing. The fruits vary in quality, some of them 
being delicious, others developing butyric acid in the process of 
ripening. This species is a positive acquisition to Florida horticul- 
ture. It will prove a desirable fruit for dooryards because of its un- 
failing habit of fruiting.
