ENUMERATION OF PHILIPPINE LEGUMINOSAE. 25 



distrilnited in the ISIalay Archipelago. It was based on the description and very 

 crude figure of Cortex saponarins given by Rumphius in "Herbarium Amboinense" 

 4 (1743) 131, pi. 66. I believe that there is very little doubt but that the 

 material cited, above represents the species, and consider it very doubtful if 

 AlMszia 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 bipinnate, the petiole 2 to 5 cm long, with a single 

 large gland at the apex; pinnge a single pair only, their rachises with a 

 gland between each pair of petiolnles; leaflets 2- to 4-jugate, the upper- 

 most ones of each pinna tlie 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 cm long and sometimes 8 cm wide, the lower ones smaller, 

 shining when dry, the base acute or rounded, the apex distinctly blunt- 

 er sharp-acuminate; nerves about G 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-wliite, 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 cm long, varying from 3.5 to 5 cm in width, 

 straiglit, indehiscent, thickly coriaceous, the base usually acute, the apex 

 acuminate or rounded, sometimes slightly refuse 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 cm long, 1.5 cm wide, and 7 or 8 mm thick, dark-reddish-brown, 

 not arillate, marked on both sides with a horseshoe-shaped scar or line.
