closely. Cultivated in the Circars according to Roxburgh to 

 feed milch cows. 



Crotalaria retusa, Linne. 



Asia, America, and Australia within the tropics. A perennial 

 herb. Its fibre resembles that of C. juncea, and is chiefly used 

 for ropes and canvas. Others of the multitudinous species of 

 Crotalaria deserve to be tested for their fibres. 



Croton lacciferus, Linne. 



Ceylon, up to 3,000 feet. Suitable for the warmer forest 

 regions here, to obtain from this tree its peculiar exuding 

 lac resin. 



Crozophora tinctoria, Necker. 



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. 



Cryptomeria Japonica, Don. 



Japan and Northern China. The Sugi ; the largest tree in Japan, 

 the trunk attaining 35 feet in circumference (Rein) ; it is also 

 grown for hedges and there yielding the most esteemed timber, 

 scented like that of Cedrela (Christie) . A slender evergreen 

 tree, sometimes over 100 feet high. It requires forest valleys 

 for successful growth. The wood is compact, very white, soft 

 and easy to work. In the Azores preferred even to the Pinus 

 Haleppensis for timber culture, on account of its still more 

 rapid growth in that insular clime. 



Cucumis cicatrisatus, Stocks. 



Scinde, where it is called " Wungee." The edible ovate fruit 

 is about 6 inches long. 



Cucumis Citrullus, Seringe. (Citrullus vulgaris, Schrader.) 



Mediterranean regions. The Water Melon. It is simply- 

 mentioned here to indicate the desirability of naturalising it 

 in the Australian interior deserts, where no Cucurbita and only 

 a single kind of edible Cucumis (C. acidus, Jacquin), with 

 fruits not larger than a pigeon's egg, is indigenous. In South 

 African deserts it has become spontaneously established, and 

 retained the characters of the cultivated fruit. 



Cucumis Colocynthis, Linnd (Citrullus Colocynthis, Schrader.) 

 From the Mediterranean regions to India. An annual herb.
