PITHECOLOBIUM Martius 
PITH ECO LOB HUM 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 
charts ceous, 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.
