except the upper exposed portion which is densely ferruginous- 

 pubescent. Calyx about 7 mm long, the tube glabrous, the lobes 

 densely pubescent. 



Mindanao, Agusan Subprovince, near Butuan, For. Bur. 21962 Sher- 

 fesee, Cenabre, & Ponce, May 22, 1914, along nipa swamps at sea level, 

 locally known as cunding. 



A very characteristic species, recognizable at once by its ferruginous 

 indumentum, its very dense inflorescences, and its unusually large leaflets. 



PITHECOLOBIUM Martius 

 PITHECOLOBIUM CAULOSTACHYUM sp. nov. 



Arbor 5 ad 10 m alta, subglabra; foliis bijugatis, circiter 

 20 cm longis, pinnis 6-foliolatis, foliolis chartaceis, lanceolatis 

 vel oblongo-lanceolatis, usque ad 11 cm longis, acuminatis, basi 

 acutis, nervis utrinque circiter 9; paniculis parce breviter hir- 

 sutis; paucifloris, usque ad 5 cm longis, plerumque fasciculatis, 

 caulinis et in ramis vetustioribus, corolla circiter 5 mm longa. 



A tree 5 to 10 m high, the panicles mostly fascicled on the 

 trunk and larger branches. Branchlets slender, grayish-brown, 

 glabrous, the younger ones somewhat puberulent. Leaves 1- 

 jugate, about 20 cm long, the rachis 2 to 3 cm long, slightly 

 puberulent, usually with two prominent glands, one between 

 the pinnae, and one at the upper two-thirds; pinnae with 6- 

 leaflets opposite, the lower subalternate, rachis puberulent, with 

 one gland between each of the two upper pairs of petiolules 

 and usually one gland below the lowermost leaflet. Leaflets 

 chartaceous, lanceolate or oblong-lanceolate, 7 to 11 cm long, 

 2 to 3 cm wide, dark-brownish when dry, shining, glabrous, 

 the apex rather slenderly and sharply acuminate, base acute; 

 lateral nerves about 9 on each side of the midrib, slender, anas- 

 tomosing; petiolules 2 mm long or less, puberulent, becoming 

 glabrous. Panicles fascicled, mostly on the trunk and larger 

 branches, occasionally a few on the ultimate branchlets, 5 cm 

 long or less, few-flowered, sparingly hirsute with short hairs. 

 Flowers white, two or three subcapitately disposed at the tip 

 of each ultimate branchlet, the subtending bracteoles narrow, 

 about 1 mm long. Calyx cup-shaped, about 1.5 mm long, gla- 

 brous or nearly so, the teeth short, acute. Corolla campanulate, 

 about 5 mm long, the tube 2.5 mm long, the lobes as long as 

 the tube, recurved, oblong, obtuse or subacute. Stamens about 

 25, the free portions of the filaments about 1 cm long, the 

 lower 2 to 3 mm united into a tube. Ovary glabrous, oblong- 

 cylindric, 2 mm long; style slender, about 13 mm long.
