of colonisation it would not be remunerative to grow Hafron 
commercially ; but as the plant is well adapted for our 
clime, it might be planted out into various unoccupied moun- 
tain localities, with a final view to naturalize it, and to 
render it thus available at a later period from native 
sources . 
Crotalaria juncea, L. 
The Sunn Hemp. Indigenous to South Asia, and also 
wideLv dispersed through tropical Australia. An annual 
herb, rising under favourable circumstances to a height of 10 
feet. In our colony Sunn can only be cultivated in the 
warmest and moistest localities. It comes in four or five 
months to maturity. The plant can also be grown as a 
fodder-herb for cattle. It requires rich friable soil. If a 
superior soft fibre is desired, then the plant is pulled while 
in flower ; if strength is the object, then the plant is left 
standing until it has almost ripened its seeds. The steeping 
process occupies about three days. For the purpose of 
obtaining branchless stems it is sown closely. 
Crotalaria retusa, L. 
Asia, America and Australia within the tropics. A peren- 
nial herb. Its fibre resembles that of C. juncea, and is 
chiefly used for ropes and canvas. Others of the multitu- 
dinous species of Crotalaria deserve to be tested for their 
fibres. 
Crozophora tinctoria, Hecker. 
South Europe, North Africa and Orient. An annual herb. 
The turnsole-dye is prepared by exposure of the juice to 
the air, or by treating it with Ammonia. 
Cucumis cicatrisatus, Stocks. 
Scinde, where it is called “Wungee.” The edible ovate 
Iruit is about 6 inches lone:.

Cucumis Citrullus, Seringe.

Mediterranean regions. The Water-Melon. It is simply 
mentioned here, to indicate the desirability of naturalizing 
it in the interior-deserts, where no Cucurbita and only a
