2. MEMECYLON TENUIPES sp. nov. 
Arbor parva, glabra, circiter 5 m alta, ramis ramulisque tenui- 
bus, teretibus ; foliis lanceolatis, coriaceis, usque ad 10 cm longis, 
basi acutis, apice longe acuminatis, nervis lateralibus obsoletis; 
inflorescentiis axillaribus solitariis, ut videtur paucifloris, pedun- 
culis tenuibus, 5 ad 6 cm longis ; fructibus ovoideis, circiter 8 mm 
longis. 
A small glabrous tree, about 5 m high, the branches reddish- 
brown or grayish, slender, terete, the branchlets terete, about 
1 mm in diameter. Leaves lanceolate, coriaceous, the upper 
surface shining, the lower slightly paler, dull, 8 to 10 cm long, 
1.5 to 2.5 cm wide, the base acute, the apex slenderly acuminate, 
the midrib distinct, but the lateral nerves and reticulations 
obsolete; petioles 2 to 3 mm long. Inflorescence axillary, soli- 
tary, long and slenderly peduncled, apparently few-flowered, 
the branches at the apex of the peduncle, short, the peduncle 
5 to 6 cm long. Flowers unknown. Fruit (immature) green, 
ovoid, about 8 mm long. 
Luzon, Province of Cagayan, Abulug River, Bur. Sci. 13835 Ramos, 
January, 1912, in forests along the river. 
A species in the group with Memecylon lanceolatum Blanco=M. cuming- 
ianum Presl, but not closely allied to that species. Its alliance appears 
to be with M. gracilipes C. B. Rob., but it is entirely different from the 
latter in form and size of its leaves.
