Rate of growth. The following results of girth measurements in high 

 forest sample plots are available : 



Stereospermum suaveolens : rate of growth in high forest sample plots.

 section in the silvicultural museum at Dehra Dun showed 53 rings for a girth 

 of 5 ft., giving a mean annual girth increment of 1-13 in. 



Coppice measurements made in 1886 by Mr. A. F. Broun at Bulla wala 

 near Dehra Dun gave the following results for Stereospermum suaveolens as
