Eleusine Coracana, Gertner.—Southern Asia, east 
to Japan. Though annual, this grass is worthy of 
cultivation on account of its height and nutritiveness, 
The large grains can be used like millet. 
Eleusine stricta, Roxburgh.—India. The increase 
of grain of this annual grass, in rich soil, is at times 
five-hundredfold. E. tocusso, Fresenius, isa valua-

Euclea undulata, Thunberg.—South Africa. Berry 
small, red, edible. Other shrubby species from the 
same portion of the globe yield also esculent fruits, 
which under superior culture may vastly improve. 
Erythroxylon Coca, Lamarck.*—Peru, “This shrub
