MITREPHORA Hook. f. & Thomson 
MITREPHORA BASILANENSIS sp. noy. 
Arbor circiter 15 m alta, partibus junioribus inflorescentiis 
floribusque prominente ferrugineo-pubescentibus ; foliis oblongo- 
lanceolatis ad lanceolatis, sursum gradatim angustatis, acumina- 
tis, basi subacutis, chartaceis, usque ad 12 cm longis, in siccitate 
pallide griseis, nitidis, nervis utrinque circiter 7, tenuibus, 
adscendento-curvatis; inflorescentiis axillaribus, depauperato- 
cymosis, paucifloris; petalis exterioribus oblongis, circiter 11 mm 
longis, interioribus unguiculatis, arcuatis, extus hirsutis; car- 
pellis paucis, hirsutis. 
A tree about 15 m high, the younger parts and the inflores- 
cence prominently ferruginous-pubescent. Branches slender, 
terete, grayish-brown, wrinkled, glabrous, the younger ones 
ferruginous-pubescent. Leaves oblong-lanceolate to lanceolate, 
firmly chartaceous, pale grayish and prominently shining when 
dry, 8 to 12 cm long, 2 to 3.5 em wide, gradually narrowed up- 
ward to the rather sharply acuminate apex, the base subacute, 
the lower surface with very few appressed hairs on the midrib 
and lateral nerves; nerves about 7 on each side of the midrib, 
slender, not prominent, curved-ascending, very obscurely anas- 
tomosing, the reticulations nearly obsolete; petioles 2 to 3 mm 
long. Inflorescence of depauperate, few-flowered, ferruginous- 
pubescent cymes in the uppermost axils, but one flower opening 
at a time, the rachis 1.5 cm long or less; pedicels about 5 mm 
long. Sepals broadly ovate, coriaceous, acute or broadly acumi- 
nate, about 3 mm long and wide, ferruginous-pubescent. Outer 
three petals spreading, oblong, about 11 mm long, 5 mm wide, 
acute or obscurely acuminate, pubescent; inner three petals 
clawed, arcuate, about 9 mm long, the claw about 5 mm in 
length, the limb subrhomboid, about 5 mm wide, the angles 
rather sharp, externally densely hirsute. Stamens indefinite, 
closely crowded, 1 mm long, the truncate connectives concealing 
the anther-cells. Carpels about 6, crowded, densely pubescent, 
about 1.3 mm long; ovules about 4; stigma glabrous, oblique. 
BASILAN, For. Bur. 20060 Miranda, October 4, 1912, not far from the 
mangrove swamp, near the Barrio of Balobato, altitude about 10 meters. 
This species somewhat resembles Mitrephora ellipanthoides Elm., the 
fiowers of which are unknown, and which may prove to be not a Mitrephora. 
The present species is readily distinguished by its differently shaped leaves
