tary, white, their pedicels glabrous, stout, about 2 cm long. 
Sepals subequal, glabrous, elliptic, broadly rounded, usually 
somewhat retuse, 10 mm long, 8 mm wide. Petals broadly ellip- 
tic, about 1.8 cm long, 1 to 1.3 cm wide, coriaceous broadly 
rounded, slightly retuse, the median exposed parts very densely 
pale-hirsute, otherwise glabrous. Stamens about 50; filaments 
5 mm long, densely hirsute; anthers ovate-lanceolate, somewhat 
acuminate, 4 mm long, densely hirsute. Ovary glabrous, ovoid, 
5-celled, ovules very numerous in each cell; style glabrous, 12 
mm long, the stigma minute, subcapitate. 
Leyte, Dagami, in forests, Bur. Sci. 15355 Ramos, August 13, 1912. 
A characteristic species, distinguishable by its rather large flowers which 
are glabrous except for the densely hirsute median parts of the petals exter- 
nally and the stamens, subequal broadly elliptic petals, subequal broadly 
elliptic sepals, and its vegetative characters; the scattered, minute, black 
glands on the lower surface are characteristic.

DILLENiA Linnaeus 
DILLENIA MONANTHA sp. nov. § Wormia. 
Arbor glabra, usque ad 12 m alta ; foliis coriaceis, ellipticis ad 
obovato-ellipticis, usque ad 12 cm longis, obtusis, acutis, vel 
latissime breviter acuminatis, basi acutis, decurrentibus, margine 
subintegris vel distanter irregulariter dentatis, nervis utrinque 
6 ad 8 ; floribus flavidis, in axillis superioribus, solitariis, circiter 
10 cm diametro, sepalis extus cinereo-pubescentibus ; carpellis 5, 
leviter hirsutis; staminibus interioribus quam exterioribus mul- 
to longioribus, antheris poro terminalibus dehiscentibus. 
A glabrous tree reaching a height of 12 m, the branches terete, 
rugose, reddish-brown or grayish. Leaves alternate, coriaceous, 
rather pale when dry, shining, elliptic to elliptic-obovate, 8 to 12 
cm long, 5 to 8 cm wide, the apex subacute, obtuse, or broadly 
and shortly acuminate, the base acute, the lamina decurrent on 
the petiole as narrow wings, the margins subentire to distantly 
dentate; lateral nerves 6 to 8 on each side of midrib, curved, 
anastomosing, distinct; petioles stout, narrowly decurrent- 
winged, 1 to 1.5 cm long. Flowers solitary in the upper axils, 
yellow, about 10 cm in diameter, their peduncles 2 to 4 cm long. 
Sepals 5, elliptic to elliptic-obovate, rounded, concave, coriaceous, 
1.5 to 2 cm long, 1 to 1.4 cm wide, outside more or less cinerous- 
pubescent. Petals yellow, obovate, membranaceous, about 5 cm 
long, 3.5 cm wide. Stamens very numerous, the interior ones up 
to 1.8 cm long, the exterior ones gradually shorter, the outermost
