132 LEGUMINOSAE. 
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 
2 or 3 scales, the end-bud lacking. 
Leaf-scars alternate, more or less 
2-ranked, somewhat 3-lobed, 
raised: bundle-traces 3, rather 
large: stipule-scars lacking. 
The julibrissin is one of the 
distinctive trees which present a 
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. 
Twigs brownish. A. Julibrissin.
