Nepal, Silhet or Srihata on the eastern extremity of Ben- 
gal, Chandpur on the Brahmaputra, and Satgar at the foot 
of the Ghat Mountains west from Madras. What are the 
circumstances that render the fruit there so excellent, I 
cannot say ; but no situations can be apparently more dis-

These are to be considered as mere varieties of a plant 
often cultivated with care, and often growing spontaneous- 
ly. In a commentary on the Perim Toddali (Hort. Mai 
iv. 85.)j I have said all that seems necessary on the sub-

aculeata, nervosis Jvliis, i?ifrii sericeis, flavis, which is the 
Zizyphus cBnoplia of Willdenow (Sp. PI. i. 1105), and the 
Z. scandens of Dr Roxburgh (Hort. Beng. 7.), who was 
probably deterred from quoting Burman, of recognizing 
the plant as the Z. cenoplia by every one of Burman"*?.
