1. A. stipulata, Benth. in Lond. Journ. Bot. iii. 92. A tree, with the 

 young shoots pubescent. Leaves of 7 to 10 pair of pinnae. Leaflets usually 

 20 to 30 pair on each pinna, oblong-linear, falcate, acute, 3 to 5 lines long ; 

 the midrib close to the inner edge. Stipules membranous, acuminate, some- 

 times near an inch long, deciduous. Peduncles usually about \ in. long, clus- 

 tered along the branches of a terminal panicle. Heads consisting of 10 to 20 

 flowers, about 3 lines long. Stamens above 1 in. long. Calyx much shorter 

 than the corolla, both pubescent. Pod 3 to 5 in. long, 9 to 10 lines broad. 



Hongkong, Hance. "Widely distributed over tropical Asia, chiefly in the mountains, from 

 Ceylon and the Peninsula to the Archipelago, and northwards to the Himalaya and S. China. 



2. A. Milletti, Benth. in Lond. Journ. Bot. iii. 89. A tree, glabrous in 

 all its parts. Leaves of 3 to 6 pair of pinnae. Leaflets 4 to 10 pair on each 

 pinna, obovate-oblong, very obtuse, \ to £ in. long, oblique at the base. Sti- 

 pules small and deciduous. Peduncles usually 2 or 3 together, along the 

 branches of a terminal panicle. Heads consisting usually of 6 to 12 flowers 

 about 2 lines long without the stamens. Calyx very much shorter than the 

 corolla, both glabrous. Filaments full ^ in. long. Pod about 6 in. long, 1£

38. PITHECOLOBIUM, Mart. 



Calyx campanulate or tubular, 5 -toothed. Corolla 5-lobed, with a cylin-

 nular or spirally twisted, opening in 2 valves. Seeds usually surrounded by a 

 thin pulp. — Trees, or rarely shrubs, without prickles. Leaves twice pinnate, 

 usually with a gland on the petiole below the pinnae, and others between one 

 or more of the pair of pinnae or leaflets. Flowers in globular or oblong heads, 

 or rarely in cylindrical spikes, usually hermaphrodite and white. 



A considerable tropical genus, distributed over the New as well as the Old World. 

 Pinna; 1 to 2 pair. Leaflets 2 to 4 pair. Branches nearly terete . . . 1. J*, lucidum. 

 Pinnse 4 to 6 pair. Leaflets 4 to 10 pair. Branches very angular . . 2. ?. clypearia. 



1. P. lucidum, Benth. in Lond. Journ. Bot. iii. 207. A tall tree, the 

 branches scarcely angular, the young ones as well as the petioles and inflores- 

 cences covered with a short rusty tomentum, but otherwise glabrous. Leaves 

 of 1 or 2 pair of pinnae. Leaflets usually 2 or 3 pair to the lower pinnae, often 

 4 or even 5 pair to the upper ones, obliquely ovate, or rarely oblong, obtusely 

 acuminate, the terminal pair often 2 in. long, the others small. Kacemes in 

 the upper axils, or forming a long terminal panicle. Peduncles seldom \ in. 

 long, solitary or clustered. Heads globular, consisting of 10 to 20 slightly pu- 

 bescent flowers. Calyx 1 line, corolla above 2 lines long. Stamens twice as 

 long. Pod about 1 in. broad, twisted into a ring, the outer edge indented 

 between the seeds. — Albizzia ? Championi, Benth. in Kew Journ. Bot. iv. 79.
