shining, the apex obtuse to broadly and shortly acuminate, base 
rounded to truncate, often inequilateral; primary nerves about 
11 on each side of the midrib, slender but distinct, spreading, 
curved, anastomosing, the reticulations distinct on the lower 
surface; petiolules 2 to 2.5 cm long. Panicles axillary, solitary, 
branched at or from near the base, up to 20 cm long, the primary 
branches up to 10 cm in length. Flowers numerous, greenish- 
yellow, fragrant, the buds obovoid. Calyx with three very short 
rounded teeth. Petals ovate, about 2.8 mm long and 2 mm wide. 
Stamens 6, their filaments about 1 mm long, inserted outside 
of the conspicuous disk which is about 1.5 mm in diameter and 
6-angled.

M1CROTROPIS PHILIPPINENS1S sp. nov. 
Frutex glaber, ramis teretibus, ramulis leviter compressis et 
obscure sulcatis ad distincte 4-angulatis ; foliis chartaceis, 
oblongo-ellipticis, usque ad 11 cm longis, in siccitate pallidis, 
nitidis, utrinque subaequaliter angustatis, acuminatis, nervis 
primariis utrinque 6 ad 8, distantibus, arcuato-anastomosanti- 
bus; cymis axillaribus, ut videtur paucifloris, breviter peduncu- 
latis; fructibus oblongo-ovoideis, circiter 1.5 cm longis, acumina- 
tis, sepalis 5, persistentibus reniformibus, 2.5 ad 3 mm latis. 
A glabrous shrub, the branches terete, the branchlets some- 
what compressed and obscurely sulcate to distinctly 4-angled, 
reddish-brown. Leaves opposite, chartaceous, pale when dry, 
shining, in general oblong-elliptic, acuminate and subequally 
narrowed at both ends, 8 to 11 cm long, 3 to 5 cm wide; primary 
lateral nerves 6 to 8 on each side of the midrib, distant, lax, 
rather distinct on the lower surface, arched-anastomosing, the 
reticulations lax; petioles 8 to 10 mm long. Cymes axillary, few- 
flowered, shortly peduncled, usually dichotomously branched, the 
two primary branches each bearing a single fruit, the peduncles 
5 cm long or less, the branches somewhat shorter than the 
peduncles. Persistent sepals 5, reniform, rounded or retuse, 
about 2 mm long, 2.5 to 3 mm wide. Fruits reddish-yellow 
when fresh, when dry dark reddish-brown, oblong-ovoid, pro- 
minently acuminate, about 1.5 cm long, 5 to 8 mm in diameter.
