the Jumna. Ravines of the Maikal and Satpura range, of the Rewah hills, and 

 of the Barrea hills east of Guzerat. Never quite leafless ; the new foliage cornea 

 out in April, May. Fl. May, June ; fr. Jan., Feb. 



Attains 60-80, and at times 100 ft. ; trunk large, erect, not regularly shaped, 

 girth 6-9 ft., at times much more. R. Thompson records specimens in the 

 Gonda forests of Oudh 100 ft. high and 19 ft. girth. Bark \ in. thick or less, 

 yellowish, or greenish white or grey, smooth, with narrow horizontal lines, 

 shallowly and distantly pitted by the falling of thin irregular scales. 



Sapwood large, often % of radius, yellowish white, not durable. Heartwood 

 light or dark brown, with broad wavy belts and patches of a darker colour^ an- 

 nual rings very indistinct. Pores numerous, large, equally distributed. Straight- 

 and even-grained, seasons well, works freely, and is durable. Weight of cub. ft. 

 40-55 lb. seasoned, 70-80 lb. green, so that it loses nearly half its weight in drying. 

 Largely used for sugar-cane crushers, rice-pounders, wheels, agricultural im- 

 plements, bridges, and house-posts. It takes a beautiful polish, and, not being ■ 

 heavy, would make' a good furniture- wood. In times of scarcity the bark, mixed 

 vnth flour, has been used as food. The bark is also used for tanning. 



Easily raised from seed, and grows readily from cuttings. Growth very rapid, 

 more rapid than of Siris. In 12 years attains 3-4, and in 30 years 4-6 ft, 

 (North India).

 are renewed in March, April, and sometimes there is a second flush in autumn. 

 The flowers chiefly appear in April, May, but often at other times. The pods
