MEMECYLON OBSCURINERVE sp. nov. § Eumemecylon. 
Frutex glaber, ramis ramulisque teretibus; foliis oblongis ad 
oblongo-ovatis, usque ad 6 cm longis, coriaceis, brevissime petio- 
latis, crasse coriaceis, acuminatis, basi acutis ad obtusis, supra 
olivaceis, subtus flavo-viridis, nervis lateralibus et transversa- 
bus subobsoletis ; inflorescentiis axillaribus, fasciculatis, circiter 
2.5 cm longis, floribus numerosis, albidis, calycis circiter 2 mm 
diametro. 
A glabrous shrub about 3 m high, the branches and branchlets 
brownish, terete, the latter smooth, about 1.5 mm in diameter. 
Leaves thickly coriaceous, oblong to oblong-ovate, 4 to 6 cm 
long, 1.5 to 3 cm wide, apex acuminate, base acute to obtuse, 
the upper surface olivaceous when dry, the lower yellowish- 
green ; lateral longitudinal nerves very obscure, scarcely visible, 
becoming obsolete in the upper part of the leaf, the transverse 
ones no more distinct than the longitudinal ones, about 6 on 
each side of the midrib, reticulations obsolete; petioles stout, 
1 to 2 mm long. Inflorescences mostly in the axils of fallen 
leaves, fascicled, peduncled, about 1.5 cm long, the peduncles 
4 to 7 mm long, mostly reduced to simple umbels, the larger 
ones with short secondary branches. Flowers numerous, white, 
their pedicels about 2 mm long, the calyces about 2 mm in 
diameter.

& Edano, August 20, 1916, on forested slopes, altitude about 400 meters. 
A species well characterized by its obscurely nerved leaves, the trans- 
verse and lateral nerves present but scarcely more than visible, the reticu- 
lations obsolete. Its alliance is apparently with Memecylon lanceolatum 
Blanco, but it is entirely different from Blanco’s species.
