 leafy branches ; pedicels '05 in. long, pubescent. Calyx '1 in. long^

This was once found by Mr. Man in the forests of South Andaman many years 

 ago ; none of the numerous collections made in the group daring recent years contain 

 any specimens of the species. It becomes quite common again in the Nicobars and 

 in the Malay Archipelago it seems to be as plentiful as it is in India and Indo- 

 China. But from the intervening Malay Pemusuia no collector has ever sent a 

 specimen to Calcutta. 



Miquel describes three varieties : — 



(a.) typica with greenish stamens. 



(j3.) vegeta with pinkish stamens. 



(7.) stipulis persistentibus with permanent, more pubescent stipules. 



But his varieties (/3.) and (7.) are only forms of one tree and that tree is what 

 constitutes in reality typical A. stipulata. What Miquel treats as VAR. typica is 

 Roxburgh's Mimosa Siyiithiana, wliich has small stipules, and is, if not a distinct 

 species, certainly a very good variety. The Andamans and Nicobars tree is true 

 A, stipulata; the other form has not been met with in our area.
