A handsome middle sized tree; stem 3 dm. thick, terete, 
12 m. high, straight; branches chiefly toward the top and form- 
ing a spreading crown, the main branches ultimately finely re- 
branched; wood moderately hard, dingy white except the yellow- 
ish brown central portion, odorless, with a distinct bitter taste; 
bark smoothish, brown; young twigs brown puberulent, finally 
glabrous. Leaves alternatingly scattered, numerous, all alike 
in size and shape, subchartaceous, glabrous, folded upon the 
upper surface, paler green beneath, drying brown, the caudate 
tips recurved, the entire margins subinvolute toward the apex, 
ovately laneeolate, obtuse at base, gradually tapering into the 
1.5 em. long apical portion which terminates in an obtusely 
rounded point, the lamina nearly 5 cm. long, 1.5 em. wide 
below the middle; midvein bold beneath clear to the apical point, 
smooth and brown, grooved along the upper side; lateral pri- 
mary pairs 9 to 11, parallel, with secondary ones between, near- 
ly straight, very obscure, reticulations none; pedicels 5 to 8 mm. 
long, slender, blackish brown in the dry state, ultimately gla- 
brate. Infrutescence from the leaf axils; stalks 2 to 3 em. long, 
similar to the petioles, divaricate, only very shortly branched
