After a careful study of the above material. T am convinced tliat tlie spt'cies 

 must be referred to Albizzia, ratlier than to FithecoIob'uDii, where it was placed 

 by Vidal. It differs from Pithecolohiutn, at least from the majority of the 

 species n<iw rcffrrct! In that genus, in its straight and indehiscent pods, tlic lirst 

 character being true of all species of Alhizzia known to me, while a nurnhir of 

 species have indehiscent pods. The seeds of Albizzia acle have on l)(»tli sides 

 rather distinct horseshoe-shaped markings, corresponding to tiie circular, oblong, 

 oval, or elliptic markings on the seeds of Albizzia- spp., and Eutcrolobium .saniaii. 

 while none of the species of Pithecolobiuni in this herbarium show corresponding 

 scars or lines. The bark of Albizzia ncle contains a consideraljle amount of 

 saponin, like that .llbizzia saponaria Plume, and like that of the latter sjiecies, 

 is used by the natives as a substitute for soap; I know of no species of Fithr- 

 colobium having this property. The wood of this species has been described by 

 Foxworthy;" it is dark-colored, moderately hard and heavy, and in structure 

 and jnoperties much more like that of various species of Albizzia than of Pithe- 

 rolobium. Among tli;' Pliilip|)inc s])ecies it is most closely allied to Albizzia 

 Ndponariu Bl. 



Albizzia acle is a valuable timber tree in the Philippines, and is widely 

 distributed at low altitudes. It is commercially known as aclc, and the tindter is 

 used for many piiiposes.
