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. 



Luzon, Camarines Province, Paracale, For. Bur. 27097 Alambra, March

 MICROTROPIS Wallich 

 MICROTROPIS PHILIPPINENSIS 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, nervls 

 primariis utrinque 6 ad 8, distantibus, arcuato-anastomosanti- 

 bus; cymis axillaribus, ut videtur paucifloris, breviter peduncu- 

 latis ; f ructibus 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.
