A mod.-sized tree with a low-spreading crown and elegant 

 2-pinnate leaves with very numerous close-set leaflets ^-J* 

 long. Pinnae 13-17, 1-2" long. Fls. small whitish sweet- 

 scented panicled. Pods spirally twisted. 



Introduced from Central America and often cultivated, esp. in S. P. 

 There are some trees about 30 ft. high at Chaibassa. Seed was 

 sent, to Singbhum and Palamau for experiment. They germinated 

 well in about a week, but it would probably be scarcely worth while 

 gi owing it on a larger scale ; Brandis say a that the pods of C digyna are 

 said to be as rich in tannin.
