OROPHEA Blume 
OROPHEA AVERSA (Elm.) comb. nov. 
Mitrephora aversa Elm. Leafi. Philip. Bot, 5 (1913) 1719. 
MINDANAO, Province of Agusan, Mount Urdaneta, Elmer 13985, October, 
1912, type number. 
This species is in all respects an Orophea, not a Mitrephora. Its inner 
petals are longer than the outer, and its stamens are miliusioid. Elmer 
has described the flowers as pistillate, but in the younger ones the stamens 
are present, stout, glabrous, about 1 mm long, few in number (apparently 
about 6), the cells not obscured by the overlapping connectives. The carpels 
are about 6 in number, about 1 mm long (not 1 dm long as described), each 
with 2 or 3 ovules. 
OROPHEA POLYANTHA sp. nov. 
Arbor parva, ramulis foliis subtus ad costa nervisque inflo- 
rescentiisque ferrugineo-pubescentibus; foliis chartaceis, in sic- 
citate brunneis, oblongis ad elliptico-ovatis, usque ad 13 cm 
longis, basi acutis, apice acuminatis, nervis utrinque 7 vel &, 
curvato-adscendentibus; inflorescentiis numerosis, extra-axillar- 
ibus, depauperato-cymosis, 1.5 ad 2 cm longis; floribus numero- 
sis, sepalis late ovatis, 3 mm longis, obtusis petalis exterioribus 
circiter 5 mm longis, patulis vel reflexis, late ovatis, interioribus 
unguiculatis, circiter 7 mm longis, arcuatis; staminibus circiter 
6, miliusioideis; carpellis circiter 6, pubescentibus. 
A small tree, the branchlets, leaves on the midrib and lateral 
nerves beneath, and the inflorescence rather prominently ferru- 
ginous-pubescent. Branches slender, terete, glabrous, very 
dark brown or nearly black when dry. Leaves chartaceous, 
brownish when dry, oblong to elliptic-ovate, 7 to 13 cm long, 
3 to 5 em wide, the upper surface somewhat pubescent when 
young, in age quite glabrous, the lower surface ferruginous- 
pubescent on the midrib and lateral nerves; lateral nerves 7 or 
8 on each side of the midrib, slender, prominent, curved-ascend- 
ing; petioles 2 to 3 mm long. Cymes depauperate, extra-axil- 
lary, among the leaves and on the branchlets below the leaves, 
numerous, solitary, the rachis 5 mm long or less, with numerous 
small bracts. Flowers few in each inflorescence, but 1 or 2 
opening at the same time, their pedicels about 1 cm long, thick- 
ened upward, ferruginous-pubescent, with an oblong, 2 mm 
long bracteole at the lower one-third. Sepals pubescent, spread- 
ing, broadly ovate, obtuse, about 3 mm long. Outer 3 petals 
similar to the sepals but larger, about 5 mm long, spreading or 
refiexed, obtuse; inner 3 petals clawed, arcuate, thick, pubescent, 
about 7 mm long, the limb subrhomboid, coarsely acuminate- 
rostrate, about 3 mm long and 2.5 to 3 mm wide. Stamens about
