poor soils but is more a tree of the open 
country and scrub jungle of which it is frequently the principal species. 
It is a moderate-^ized deciduous tree, frequently with a crooked 
irregular stem. A red astringent gum exudes when incisions are 
made in the bark. The leaves are in threes, but shoots with single 
leaves may sometimes be found. The flowers, which appear in late 
March and April, are red (occasionally yellow), and the tree is often 
popularly known as “ flame of the forest ”. The. fruit is a bean, 
ripening in the hot weather. The leaves follow the flowers and fall 
in February, so that the tree is bare from February to April. The 
wood is used little for timber, but frequently for fuel, although the 
tree is now generally conserved for the cultivation of lac. It is very 
easy to propagate from seed and will grow rapidly to 18 inches 
girth and 20 feet high in 15 years (10 years if irrigated). It coppices 
very well, is frost-hardy and drought-hardy and rarely browsed even 
by goats. The formation of regular Palas plantations, though easy, 
is not recommended, as Ber is equally easy to establish and will give
