in axils of small gland-bearing bracts on angular branchlets 4-10 in. 

 long, tliemselves fascicled in axils of bracts with a large basal gland and 

 a foliar simplj-pinnate rudimentary lamina, so as to form a terminal 

 panicle extending into axils of npper leaves, 15-20 in. long, 12-18 in. 

 wide; pedicels of florets •2--25 in. long, bracteoles minute or obsolete. 

 Calyx puberulous, campanulate, "05 in. long, teeth short acute. Corolla 

 pale-yellovv or white, -2 in. long, tube infundibuliform, teeth lanceohite 

 half as long; uniformly sparingly silky. Staments united in a tube 

 nearly as long as that of corolla, filaments white or faintly tinged with 

 pink, -6 in. long. Ovary puberulous, shortly stalked. Pod spirally 

 twisted, 7-8 in. long, '7 in. wide, dehiscing along the lower suture, 

 valves firmly coriaceous, red opposite the seeds elsewhere orange and 

 puberulous externally, red and glabrous within ; distinctly sinuate 

 between the seeds on the lower margin, stipe very short. Seeds 8-10, 

 ovate-oblong, '5 in. long, '35 in. wide, 2 in. thick, testa dark-purple, 

 dull, thin, crustaceous. Miq. Flor. Ind. Bat. I, 34 ; Bak. in Flor. Brit.

A rather variable species, with two leading types, hardly, however, to bo 

 distinguished even as varieties owing to the number of intermediate forms that 

 occur. Of these, (a.) heterophylla — the original plant of Roxburgh with large 

 term.inal leaflets — extends from the Himalaya to Chittagong, the Andamans and 

 Sumatra. This is very uniform in character and constitutes both Inga acutangula 

 Grab. (Wall. Gat. 5271), and Pithecolohium acutangulum Miq., although it happens 

 that Miquel when describing P. acutangulum conceived it to be different from Inga 

 acutangula. The other plant, (j8-) intermedia — with smaller terminal leaflets and . 

 usually more numerous pinnae and leaflets — extends from Upper Burma east of the 

 Irrawaday though the Shan Plateau to Tennsserim, the Mtilay Peninsula and Java. 

 This is less uniform than the preceding and often has leaflets so like those of P. 

 Clypearia that it can only be safely distinguished by its longer pedicels and sessile 

 glands. This is the plant of JFall. Cat. 5270 C, from Penang, and is the Pithecolohium 

 angulatum of Miquel as opposed to that author's P. acutangulum. P. angulatum 

 Benth., like P. angulatum as defined in this paper, includes both plants.
