PHILIPPINE PLANTS, IX. 267 
subcoriaceous, shining, green and of about the same color on 
both surfaces, 10 to 18 cm long, 4 to 8 cm wide ; lateral nerves 8 
to 10 on each side of the midrib, prominent, curved upward, 
anastomising, the reticulations lax; petioles 7 to 10 mm long. 
Flowers perfect, yellow and purple, extra-axillary or leaf-opposed, 
solitary, or at least but one flower opening at a time, the short 
rachis, the bracts, and the calyx externally densely ferruginous- 
pubescent. Sepals broadly ovate, acute or slightly acuminate, 
about 6 mm long. Outer three petals oblong, acute or somewhat 
obtuse, about 2 cm long, 8 mm wide, externally somewhat ap- 
pressed-pubescent with brown hairs, inside glabrous, the inner 
three petals about 14 mm long, vaulted, conniving, their claws 
slender, glabrous, about 9 mm long, their limbs about 5 mm long, 
subrhombic, but when spread much wider than long, the inner 
surface ^very densely ciliate- villous with long, dark-brown hairs. 
Stamens indefinite, narrowly oblong, 1 to 1.2 mm long, their 
connectives truncate, overlapping. Ovaries 12 to 15, glabrous, 
1 to 1.2 mm long, oblong; ovules about 12, 2-seriate; styles 
clavate-oblong. Fruits unknown. 
BusuANGA (Calamianes Islands), C. M. Weber 1550bis, February 25, 
1911, in forests, limestone region, altitude about 30 meters. 
Apparently a very characteristic species, distinguishable by the inner 
faces of the limbs of the interior petals being very densely ciliate-villous 
with long, dark-brown hairs, and by its outer petals being quite glabrous 
inside.

Frutex scandens omnibus partibus plus minusve ferrugineo- 
pilosis, ramulis densissime pilosis; foliis oblongis vel anguste 
oblongo-obovatis, abrupte brevissime acuminatis, basi leviter 
cordatis, subcoriaceis vel chartaceis, usque ad 24 cm longis, nervis 
utrinque circiter 10, distantibus, distinctis; petiolo crasso, vix 
6 mm longo;.floribus ignotis; fructibus ovoideis vel ellipsoideis, 
circiter 8 cm longis, aurantiacis, ferrugineo-pilosis. 
A scandent shrub, all parts more or less ferruginous-pilose, 
the branchlets very densely so, the older branches bearly black, 
lenticellate, becoming glabrous. Leaves subcoriaceous or firmly 
chartaceous, oblong or narrowly oblong-ovate, 14 to 24 cm long, 
5.5 to 8.5 cm wide, usually widest above the middle, the apex 
shortly and abruptly acuminate, below usually more or less nar- 
rowed, the base rounded, somewhat cordate, both surfaces more 
or less pilose with ferrugenous hairs, the upper surface in age 
becoming more or less glabrous, the lower surface slightly paler,
