ENUMERATION OF PHILIPPINE LEGUMINOSAE, 25 
distributed in the Malay Archipelago. It was based on the description and very 
crude figure of Cortex saponarius given by Rumphius in “Herbarium Amboinense” 
4 (1743) 131, pl. 66. I believe that there is very little doubt but that the 
material cited above represents the species, and consider it very doubtful if 
Albizzia tomentella Miq. will prove to be distinct. The bark contains a consider- 
able amount of saponin, and is used throughout the Philippines as a substitute 
for soap. The species is variable in vegetative characters, large and small leaflets 
being frequently found on the same specimen.

A tree, reaching a height of 25 or 30 m, glabrous or nearly so except 
the inflorescence. Branches terete, gray or brown, usually strongly 
lenticellate. Leaves brpinnate, the petiole 2 to 5 cm long, with a single 
large gland at the apex; pinne a single pair only, their rachises with a 
gland between each pair of petiolules; leaflets 2- to 4-jugate, the upper- 
most ones of each pinna the largest, when young very thinly membra- 
naceous, becoming chartaceous, or ultimately even subcoriaceous, ovate 
to elliptic-ovate or oblong-ovate, often somewhat inequilateral, the largest 
ones up to 18 em long and sometimes 8 cm wide, the lower ones smaller, 
shining when dry, the base acute or rounded, the apex distinctly blunt- 
or sharp-acuminate; nerves about 6 on each side of the midrib, distinct, 
anastomosing, the reticulations rather lax; petiolules 1.5 to 3 mm long. 
Inflorescences usually appearing with the leaves, axillary, softly pubes- 
cent, of many, fasciculate, rather densely disposed short panicles, the 
ultimate branches or peduncles to the heads of flowers 4 cm long or less. 
Flowers greenish-white, sessile, 10 to 15 in each head. Calyx somewhat 
tubular, pubescent, about 3 mm long, with 5 short teeth. Corolla pubes- 
cent, narrowly funnel-shaped, about 7 mm long. Stamens many, much 
exserted. Pods 20 to 40 em long, varying from 3.5 to 5 cm in width, 
straight, indehiscent, thickly coriaceous, the base usually acute, the apex 
acuminate or rounded, sometimes slightly retuse and apiculate, con- 
stricted between the seeds, but without dissepiments, opposite the seeds 
much inflated, ultimately breaking irregularly across the pods at the 
constrictions between the seeds, and also breaking from the continuous 
and somewhat thickened margins. Seeds 10 to 12 in each pod, elliptic, 
about 2 em long, 1.5 em wide, and 7 or 8 mm thick, dark-reddish-brown, 
not arillate, marked on both sides with a horseshoe-shaped scar or line.
