Province, Mount Binuang, near Infanta, Bur. Sci. 9383 Robinson, August, 
1909, altitude 875 meters. Bur. Sci. 28666 Ramos & Edano, May 27, 1917. 
A species characterized by its very thick, round to broadly obtuse, sessile 
leaves. It is perhaps as closely allied to Memecylon diversifolium Presl, 
as any other species, but cannot be referred to Presl’s species, the type of 
which was from Malacca, not from the Philippines, and which proves to 
be a synonym of Memecylon coeruleum Jack. 
MEMECYLON SYM PLOCI FORM E sp. nov. § Eumemecylon. 
Frutex glaber, circiter 5 m altus, ramis ramulisque teretibus, 
tenuibus ; foliis coriaceis, oblongo-ellipticis ad oblongo-lanceolatis, 
usque ad 8 cm longis, petiolatis, utrinque subaequaliter angus- 
tatis acuminatisque, nervis reticulisque obsoletis ; infructescentiis 
axillaribus, brevibus, fructibus ellipsoideis vel oblongo-ovoideis, 
circiter 1 cm longis, basi distincte inaequilateralibus. 
A glabrous shrub about 5 m high, the branches and branchlets 
slender, terete, the ultimate branchlets less than 1 mm in diam- 
eter, brownish or pale. Leaves greenish-olivaceous, slightly 
shining, the midrib prominent, the lateral nerves and reticula- 
tions obsolete on both surfaces, coriaceous, oblong-elliptic to 
oblong-lanceolate, 5 to 8 cm long, 1.8 to 3 cm wide, subequally 
narrowed to the acuminate base and to the rather slenderly 
acuminate apex; petioles 2 to 3 mm long. Infructescences axil- 
lary and from the axils of fallen leaves, the peduncles about 5 
mm long, simple or with two short branches at the apex, each 
bearing one or two fruits. Fruits ellipsoid or oblong-ovoid, 
about 1 cm long, brown and smooth when dry, the base distinctly 
inequilateral, rounded on one side, acute on the other. 
Luzon, Tayabas Province, Pacific coast, vicinity of Mount Dingalan, 
Bur. Sci. 26598 Ramos & Edano, August 27, 1916, on slopes, altitude about 
196 meters, the fruits described as white when fresh, the local (Bulugo) 
name ambatiki. 
A species well characterized by its acuminate, nerveless leaves and its 
somewhat elongated fruits which are distinctly inequilateral at the base. 
In aspect it rather strongly resembles some species of Symplocos. Its 
alliance is apparently with Memecylon lanceolatum Blanco and M. gitingense 
Elm., from both of which it is at once distinguished by its fruit characters.
