Albizzia. 

 (Family Leguminosae). 



Trees: deciduous. Twigs mod- 

 erately slender, angled, with rath- 

 er evident lenticels: pith mod- 

 erate, angular, continuous. Buds 

 superposed, sessile, round, with 

 ffTll 2 or 3 scales, the end-bud lacking. 



Leaf-scars alternate, more or less 

 Q[ 2-ranked, somewhat 3 - 1 o b e d , 



raised: bundle-traces 3, rather 

 large: stipule-scars lacking. 



The julibrissin is one of the 

 distinctive trees which present a 

 \ I tropical appearance because of 



their feathery foliage. This is 

 most seen in the/ North in the 

 locust and rose acacia, both be- 

 longing to Robinia, and especially 

 in the honey locust, Gleditsia. 

 From Washington southward, this 

 effect becomes more striking as 

 the still more delicate Albizzia is 

 encountered, and as subtropical and tropical conditions are 

 reached the variety of trees of this type increases. A some- 

 what similar effect is produced by a few genera like Zizyphus 

 and Coriaria which bear simple leaves but produce clusters 

 of slender leafy twigs each year which simulate tufts of 

 compound leaves. 



In the West Indies, a graceful tree of this genus {A. 

 Lebbek) is much planted under the name of woman's 

 tongue, its thin clustered legumes rustling pleasingly on 

 every impulse.
