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, Btir. 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 cor.iaceis, 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
