shaped, truncate, not at all toothed, 2 mm in diameter. Petals 
about 1.3 mm long. Buds obtuse or broadly and obtusely 
apiculate. Berry broadly ovoid, obtuse.

A species very similar to and manifestly closely allied to Memecylon 
paniculatum Jack, as here interpreted, differing especially in its decidedly 
pale leaves which are minutely pustulate on the lower surface, not entirely 
smooth and brown as in the material referred to Jack’s species.

This species, although manifestly allied to Memecylon paniculatum Jack, 
is certainly specifically distinct. It is readily distinguished by its much 
less prominently nerved leaves, the marginal nerves not at all prominent, 
and its terete, or obscurely sulcate but not 4-angled ultimate branchlets. 
It was reduced to Memecylon paniculatum Jack by Triana, in which he was 
followed by Cogniaux. The type was from the small settlement of Cal- 
dera a few miles north of Zamboanga, and between Zamboanga and San 
Ramon.

The species is similar in many respects to Memecylon pteropus Merr., 
but differs essentially in its much shorter inflorescences, the peduncles and 
branches grooved, not 4-angled, and not at all winged as in M. pteropus.

Arbor parva, circiter 5 m alta, glabra ; ramis teretibus, ramu-

acuminatis, usque ad 13 cm longis, 3-nerviis, nervis transversa- 
libus prominentibus, rectis, utrinque circiter 12; inflorescentiis

4-alatis; fructibus globoso-ovoideis, purpureis, circiter 7 mm

A small tree, quite glabrous, the branches terete, reddish- 
brown, the branchlets sharply 4-angled, narrowly 4-winged, the 
ultimate ones 2 to 3 mm in diameter. Leaves oblong-ovate, 
coriaceous, shining, subsessile, the petioles 2 mm long or less, 
the base broadly rounded-cordate, narrowed from the middle or 
the lower third upward to the acuminate apex, 7 to 13 cm long, 
3 to 13 cm wide; lateral longitudinal nerves distinct, slightly
