2. Radermachera elliptica sp. nov. 
Arbor glabra; foliis pinnatis, circiter 35 cm longis; foliolis 5, ellipticis 
vel obovato-ellipticis, usque ad 15 cm longis, basi acutis vel acuminatis, 
apice late rotundatis vel breviter obtuseque acuminatis, nervis utrinque 
9; paniculis axillaribus, circiter 15 cm longis, densis; floribus 5 cm longis, 
calycibus 2 cm longis, obliquis, j uni oil bus clausis; fractibus 20 ad 25 cm 
longis. 
A tree, glabrous throughout. Branches terete, brown, strongly lenticel- 
late. Leaves simply pinnate, about 35 cm long: leaflets 5, elliptical or 
obovate-elliptical, 12 to 15 cm long, 7 to 9 cm wide, coriaceous, shining, 
the base acute or somewhat acuminate, the apex broad, rounded, or very 
shortly and broadly obtusely acuminate; nerves about 9 on each side of 
the midrib, distinct, anastomosing, the reticulations lax; petiolules about 
1.5 cm long, t"hat of the terminal leaflet short, but the rachis produced 
about 5 cm beyond the upper pair of leaflets. Panicles axillary, about 
15 cm long, peduncled, densely flowered, more or less resinous and 
shining. Flowers white. Calyx about 2 cm long, closed in bud, obliquely 
split in anthesis, not toothed, submembranaceous, smooth, not at all 
ridged. Corolla 5 cm long, the tube somewhat abruptly enlarged where it 
emerges from the calyx, about 1.5 cm in diameter above, the lobes broadly 
ovate, rounded, 1 cm long, somewhat hairy inside at the insertion of the 
anthers; filaments glabrous. Capsules 20 to 25 cm long, nearly cylin- 
drical, slightly compressed, glabrous, shining, 7 to 8 mm in diameter, 
the apex somewhat acuminate; seeds numerous, including the wings 1.3 
cm long. 
Luzon, Province of Bulacan, Angat, For. ' Bur. llUil Aguilar, April, 1908. 
Well characterized by its pinnate leaves, elliptical coriaceous leaflets, and large 
flowers. Not closely allied to any other known Philippine species.

Luzon, Province of Benguet, Sablan, Elmer 6119 (type), April, 1904: Province 
of Cagayan, Bolster 131/, July 15, 1905. Palawan, Balsajan River, Bur. Sci. 581/ 
Fox worthy, March, 1906; Cabudlungan, For. Bur. 5190 Curran, August, 1906. 
N. v., Agtap, in Palawan. 
This species is well characterized by its very large flowers, those in the type 
being 6 cm long, and, according to the collector, pink in color, while those of 
Bolster's specimen are 6.5 cm long and said by him to be white and more or 
less yellow inside. The Palawan specimens differ from the type in having some- 
what smaller flowers (5.5 cm), which are said by Foxworthy to be white and 
fragrant. I can not, however, find any valid characters in the material at hand to 
warrant the separation of any of the above as distinct species, although additional 
material may show such a course to be desirable.
