XIV, 4 Merrill: Noteworthy Philippine Plants, XV 421 
April 7, 1916, along streams in open forests, altitude about 100 
meters. ; 
This species has almost exactly the vegetative characters of 
Pterospermum blumeanum Korth. (P. javanicum Jungh.) and 
the second specimen cited above, which has only immature buds, 
was originally so identified. While it is manifestly closely allied 
to Korthals’s species, it differs remarkably in its larger flowers, 
somewhat longer and much broader sepals, and in its much larger 
petals, which exceed the sepals in length. 
DILLENIACEAE 
DILLENIA Linnaeus 
DILLENIA MEGALOPHYLLA sp. nov. § Wormia. 
Arbor, inflorescentiis exceptis glabra, ramulis ultimis 1.5 ad 
2 cm diametro; foliis coriaceis, ovatis ad elliptico-ovatis, usque 
ad 1 m longis, apice rotundatis, basi angustatis, margine undu- 
latis vel obscure dentatis, nervis utrinque 15 ad 18, perspicuis, 
lamina decurrente, basi conduplicatis ; inflorescentiis axillaribus, 
longe pedunculatis, paucifloris, circiter 40 cm longis, dense pubes- 
centibus; sepalis coriaceis, obovatis ad late ellipticis, 3 cm longis, 
extus molliter dense fulvo-pubescentibus ; carpellis plerumque 8. 
A tree, about 7 m high, nearly glabrous except the inflores- 
cences, the ultimate branches 1.5 to 2 cm in diameter. Leaves 
coriaceous, ovate to elliptic-ovate, up to 1m long and 60 cm wide, 
apex rounded, base gradually narrowed, margins somewhat un- 
dulate and obscurely toothed, glabrous on both surfaces, what is 
apparently the petiolar part of the leaf with the lamina contin- 
uous but with much slenderer nerves than the leaf proper, ex- 
tending to the very base of the petiole, conduplicate, the upper 
surface for a distance of about 2.4 cm on each side of the midrib 
closely appressed and with a modified, brown, apparently absorb- 
ent epidermis, this region in some leaves inhabited by colonies 
of ants, the lower surface of this conduplicate area rather softly 
pubescent; lateral nerves above the modified petiolar part of the 
lamina very prominent, 15 to 18 on each side of the midrib. In- 
florescences in the uppermost axils, long-peduncled, few-flowered, 
sparingly branched above, about 40 cm long, densely and softly 
pubescent; pedicels 3 to 5 em long. Sepals coriaceous, obovate 
to broadly elliptic, rounded, concave, about 3 cm long, softly and 
densely fulvous-pubescent externally. Petals not seen. Sta- 
mens apparently equal or subequal. Carpels usually 8, glabrous, 
not twisted, the styles up to 3 cm long. Immature carpels coria- 
ceous, about 3 cm long, apparently purplish, dehiscent; ovules 
about 11 in each carpel; immature seeds with a small basal aril.
