THE DICOTYLEDONES 1749 



carbohydrate content between 9 and 15 per cent, of the weight. The 

 protein content is low, being about 1-5 per cent. 



Fig. 1627. — Artocarpus incisa. Breadfruit Tree. Shoot 

 with young fruits. 



The Jack fruit (A. integrifolid) is similar to the Breadfruit, but differs 

 in that the fruits in this species are borne on the trunk and not on the 

 branches. The tree may reach 70 ft. in height and the aggregate fruits are 

 very large, in fact they are probably the largest in the world, being oval in 

 shape and 2 ft. in length, weighing up to 80 lb. 



The third species is the Marang {A. odoratissima) which is a native of 

 the Philippine Islands. The fruit is about 6 in. long and covered with short 

 spines. The flesh is white, sweet, juicy and aromatic, with a pleasant flavour. 

 It separates into segments each the size of a grape, which represent the 

 individual fruits. 



In addition to their important fruits the leaves of species of Artocarpus 

 are used. The leaves are oval, about 2 ft. long, and dry very easily. When 

 ground into a meal they form an excellent cattle food which has up to 24 

 per cent, of protein in it. The seeds are also ground and used for livestock, 

 and though the protein yield is only 14 per cent., they contain some 64 per 

 cent, of carbohydrates. 



Several other genera are of economic importance and worthy of brief 

 mention.
