MITREPHORA FRAGRANS sp. nov. 
Arbor 8 ad 10 m alta, partibus junioribus dense ferrugineo- 
pubescentibus ; foliis coriaceis, oblongo-ovatis ad elliptico-ovatis, 
usque ad 26 cm longis, junioribus utrinque ad costa nervisque 
plus minusve ferrugineo-pubescentibus, vetustioribus glabrescen- 
tibus, obtusis vel obtuse acuminatis, basi subacutis ad subrotun- 
datis, nervis utrinque 13 ad 16, valde prominentibus ; fioribus 
paucis, usque ad 11 cm diametro, petalis exterioribus accrescen- 
tibus; carpellis circiter 10; ovulis 16 ad 20. 
A tree 8 to 10 m high, the branchlets, young petioles, pedicels 
and buds densely ferruginous-pubescent. The branches terete, 
nearly black when dry, more or less ferruginous-pubescent, be- 
coming glabrous. Leaves coriaceous, pale when dry, slightly 
shining, oblong-ovate to elliptic-ovate, 10 to 26 cm long, 5 to 
11 cm wide, apex obtuse to obtusely acuminate, base subacute 
to subrounded, both surfaces more or less ferruginous-pubes- 
cent on the midrib and lateral nerves, in age becoming glabrous 
or nearly so ; lateral nerves 13 to 16 on each side of the midrib, 
very prominent. Flowers perfect, fragrant, opening pale yel- 
lowish-white, turning bright orange-yellow, extra-axillary, soli- 
tary, their pedicels 1 cm long or less, with 2 or 3 subverticillate, 
broadly ovate, coriaceous, ferruginous-pubescent, about 7 mm 
long bracteoles near the apex. Sepals broadly ovate to oblong- 
ovate, 10 to 14 mm long, obtuse, more or less ferruginous-pubes- 
cent. Outer petals 3 cm long at anthesis, accrescent and soon 
5.5 cm long and up to 4 cm wide, oblong-ovate to obovate, acu- 
minate, base narrowed, outside rather densely pubescent, inside 
sparingly so; inner petals vaulted, deciduous, nearly 3 cm long, 
the claw slender, 1.5 cm long, the limb subrhomboid, obtuse, 
about 12 mm wide, externally slightly pubescent, internally 
hirsute. Stamens very numerous, crowded, 1.5 mm long, con- 
nectives broad, truncate, slightly oblique. Carpels about 10, 
crowded, densely pubescent, narrowly oblong, narrowed upward, 
about 1.8 mm long; ovules 16 to 20. 2-seriate. 
Palawan, Taytay, Merrill 9217, April, 1913, on forested slopes of a small 
■valley, altitude about 40 meters. 
The flowers open, pale yellowish-white, the external petals then being 
about 3 cm long; the inner three arched petals are marked with purple, and 
are early deciduous, but the external petals persist for some time, are 
accrescent, and gradually turn bright orange-yellow. The species is well 
characterized by its unusually large flowers, and although its vegetative 
characters resemble those of Mitrephora williamsii C. B. Rob., the two 
species are not at all closely allied.
