Niemeyera prunifolia, F. v. Mueller.—The Austra- 
lian Cainito. An evergreen tree, sparingly dispersed

coast forests of Queensland. The fruit is of plum-like 
appearance and edible. Culture is likely to improve 
its quality. 
Ocimum Basilicum, L.—The Basil. Warmer parts 
of Asia and Africa. An annual herb, valuable for
