Aristolochiee.] THE HIMALAYAN MOUNTAINS." 329 
(Lfevea guianensis, Aubl.), a tree of Guiana and Brazil, which would no doubt thrive 
in Bengal. Caoutchouc is also imported from Penang, the produce of Urceola elastica 
(As. Res. v. p. 157 and 167), but I hope it will be also from the continent of India. 
The expressed oil of the seeds of Jatropha Curcas, boiled with oxide of iron, is said 
to form the varnish used by the Chinese for covering boxes (Lindley.) The juice of 
this plant is of a very tenacious nature, and when blown into, forms very large bubbles, © 
probably owing to the presence of Caoutchouc ; this is also afforded by an African tree 
of this order. 
The dye called Turnsol, is yielded by Crozophora (Croton) tinctoria, as is a colouring 
matter by C. plicata (v. Roxb. FI, Ind. iii. p. 68); also by Rottlera tinctoria, of which 
the strigose pubescence, like that of Aucuna pruriens, is administered for expelling 
intestinal worms. Several of this family yield hard and valuable timber in India, 
as Emblica officinalis, Rottlera tetracocca, Adelia castanicarpa, species of Briedelia, 
Cluytia, &c. African oak or teak is supposed by some to belong to this family. 
Though belonging to so dangerous a family, the leaves of Plukenetia corniculata are 
said to be eaten as a vegetable; and the domesticated Arindy silk-worm (Phalena 
Cynthia) is fed upon the leaves of Ricinus communis. (Roxb.)

147. ARISTOLOCHIEZ. 
The Aristolochie@ are chiefly found in tropical countries, especially S. America, the 
West-Indies, and the southern provinces of N. America. Asarum occurs in Europe, 
Japan, and N. America, with a few species of Aristolochia. Species of the last and 
Bragantia are found in the Indian and Malayan Peninsulas. A. saccata occurs in the 
mountains of Silhet, and A. bracteata spreads from the Peninsula to the banks of the 
Jumna. A. indica is common to India and New Holland. 3
