or in pairs, globose, glabrous, rather coarsely wrinkled, brown

fruits, its leaves dark-colored when dry, with less prominent nerves and 
quite different reticulations. 
CYCLOSTEMON MINDANAENSIS sp. nov. 
Arbor glabra, circiter 15 m alta; foliis oblongis, inaequilat- 
eralibus, coriaceis, usque ad 18 cm longis, in siccitate nitidis, 
flavido-brunneis, integris vel distanter irregulariter crenato- 
serrulatis, obtuse acuminatis, basi acutis, nervis utrinque circiter 
6, curvato-adscendentibus ; fructibus axillaribus, fasciculatis, 
oblongo-ovoideis, acutis, circiter 2.5 cm longis, in siccitate pal- 
lide brunneis, minute verruculosis, 1- vel 2-locellatis. 
A tree apparently about 15 m high, glabrous or nearly so. 
Branches terete, or somewhat angular, pale when dry, smooth. 
Leaves oblong, more or less inequilateral, coriaceous, 12 to 18 
cm long, 3 to 6 cm wide, entire or distantly and irregularly 
crenate-serrulate, gradually narrowed to the blunt-acuminate 
apex, the base acute, or acute on one side and somewhat rounded 
on the other, yellowish-brown when dry, of about the same color 
and strongly shining on both surfaces; primary lateral nerves 
about 6 on each side of the midrib, curved-ascending, anastomos- 
ing, distinct, the reticulations evident on both surfaces; petioles 
5 to 8 mm long. Flowers not seen. Fruits axillary, fascicled, 
2 to 4 or more in each axil, oblong-ovoid, acute, base obtuse, 
about 2.5 cm long, 10 to 12 mm in diameter, pale-brown when 
dry, minutely verruculose, when young sparingly pubescent, 1- 
or 2-celled, the pedicels about 1 cm long, when young appressed- 
pubescent, becoming quite glabrous.

The specimens were originally placed under Stemonurus, and the dup- 
licates of both were probably distributed under this generic name; the 
species, however, is a euphorbiaceous plant and undoubtedly belongs in 
the genus Cyclostemon. It is well characterized by its strongly shining, 
pale leaves and its oblong-ovoid, acute fruits. The Moro name recorded 
by Tarrosa is banaui.
