Luzon, Tayabas, Malicboi (Merrill no. 2447 in flower in 

 April). 



4. Semecarpus Merrill iaiia Perk. n.sp. Tree 10 m high (ex Merrill); 



young branches rather slender, with pale glabrous bark. Leaves 

 simple, alternate, chartaceous, lanceolate- oblong or lanceolate, 

 rather long acuminate, tapering from the middle to the very 

 narrow base, upper surface shining, glabrous except the im- 

 pressed pubescent midrib, beneath gray -brown, hirsute -pilose, 

 especially at the nerves; main nerves 12 — 18, above incon- 

 spicuous, beneath prominent, spreading, interarching near the 

 edge; length 10 — 17,5 cm, breadth, 2,5 — 5 cm; petiole 1,5 — 2 cm 

 long, glabrous. Racemes axillary, pedunculate, pubescent, shorter 

 than the leaves; branches few. Flowers rather crowded, sub- 

 sessile, globular in bud, about 3 mm in diam. when expanded. 

 Male flowers calyx cupular, flat, with 5 ovate, acute, hirsuto- 

 puberulous spreading teeth. Petals 5, ovate -oblong, obtuse, 

 both surfaces sub -pilose, several times longer than the calyx; 

 stamens 5, much longer than the petals, filaments flattened, 

 glabrous. Disk in the middle pilose. 



Island of Paragua, San Antonio Bay (Merrill no. 851). 

 This species is nearly related to Semecarpus philippinensis Engl, 

 from which, however, it differs in its inflorescence, and in 

 the shape and pubescence of its leaves. 



5. Semecarpus micrantlia Perk. n. sp. Tree 10 m high (ex Merrill); 



young branches rather stout, with pale glabrous bark. Leaves 

 entire, simple, alternate, coriaceous, obovate or obovate- oblong, 

 suddenly and very shortly acuminate, gradually narrowed in 

 the lower half to the short, dilated petiole; the upper surface 

 glabrous, brown when dry; the lower pale brown when dry, 

 not shining, glaucescent; main nerves 13 — 19, stout, shining, 

 broad and conspicuous on the lower surface, thin and only 

 slightly prominent on the upper, spreading, slightly ascending, 

 interarching near the edge, length 9 — 13 cm, breadth 4 — 5,5 cm; 

 petiole 1,5 — 2cm long. Panicles terminal, pedunculate, longer 

 than the leaves, rusty -puberulous; the branches slender, long, 

 lax; the branchlets short and bearing the flowers in rather short 

 fascicles. Male flowers 3 mm in diam.; calyx cupular, fiat, 

 with 5 spreading, minute, acute teeth, yellow-pubescent out- 

 side; petals 5 membranous, oblong, obtuse, externally thinly,
