Z. sativa. Gcert. i. p. 202. t. 43./! 4. 



A pretty large tree, often as large as a full-grown apple tree 

 in England, a native of Persia and Hindoost'han ; only found 

 in gardens in Bengal, where it blossoms in August, and the 

 fruit ripens in January. 



6. Z. nitida. /?. 



Arboreous. Thorns stipulary, one projecting, one recurv- 

 ed. Leaves obliquely ovate-oblong, three nerved, obtusely 

 serrate, smooth. Fruits sub-cy limbic ; nuts two-celled. 



Introduced from China into the Botanic garden at Calcut- 

 ta, where it grows to be a small tree. "Flowering time the hot 



season. 



Root superficial, sending up many suckers for some yards 

 round the tree. Trunk generally crooked. Bar A: brown, 

 pretly smooth ; branches few, flexuose, and thin of leaves. 

 Spines stipulary, the upper one straight, long, and pointing 

 much forward, the other shorter and recurved. Leaves al- 

 ternate, short petioled, obliquely oblong, emarginate, three- 

 nerved, serrate, smooth, of a shining green on both sides, 

 from one to two inches long. Flowers axillary, few, collect- 

 ed on short common peduncles ; they are small, yellow, semi- 

 digynous. Drupe oblong, pendulous and smooth, about an 

 inch long, when ripe pale-yellow. Nut lanceolate, pointed 

 at both ends, a little compressed, rugose, two-celled. 



The fruits are eaten, but to my taste they are rather insi- 

 pid. Innumerable suckers constantly rise from the root 

 which run to a great distance from the parent tree, and make
