lower ones up to 12 cm long, all parts rather softly pilose with 
pale-brownish hairs. Fruits 2 cm long, 2-keeled, 2-winged, very 
sparingly pilose or glabrous, the fruit proper about 5 mm wide, 
the wings chartaceous, brown, shining, rounded, the total width 
of the fruit with the wings about 4.5 em, the wings broadly

LuZzON, Subprovince of Lepanto, near Cervantes, Vanoverbergh 2135, 
November 12, 1912, in thickets along streams. 
A species quite different from the other Philippine forms, and ap- 
parently not previously described. The pubescence of the leaves and 
inflorescence is characteristic. Unfortunately it cannot, in the absence 
of flowers, be referred to its proper section.

PYGEUM Gaertner 
PYGEUM RAMIFLORUM sp. nov. 
Arbor parva, partibus junioribus inflorescentiisque dense 
ferrugineo-pubescentibus; foliis coriaceis, ellipticis ad oblongo- 
ellipticis, usque ad 8 cm longis, breviter acuminatis, basi acutis 
ad rotundatis, haud glandulosis, subtus ferrugineo-pubescentibus 
ad costa nervisque; inflorescentiis paniculatis, axillaribus, e 
ramis defoliatis, 2 ad 3 cm longis, dense multifloris; floribus 
6-meris; ovario villoso; staminibus 18 vel 21. 
A small tree, 3 m high according to the collector, the young 
branches and leaves, petioles, the inflorescences, and the lower 
surfaces of adult leaves on the midrib and nerves densely fer- 
ruginous-villous. Older branches terete, glabrous, grayish or 
brownish. Leaves elliptic to oblong-elliptic, coriaceous, 6 to 8 
cm long, 3 to 5 cm wide, entire, apex shortly acuminate, base 
acute to rounded, not glandular, the upper surface becoming 
glabrous or nearly so, somewhat shining, the nerves impressed, 
the lower surface much paler, brownish, prominently ferruginous- 
villous on the midrib and nerves; lateral nerves about 8 on each 
side of the midrib, very prominent; petioles densely pubescent, 
about 8 mm long; stipules oblong-ovate, somewhat oblique, very 
densely pubescent, caducous. Panicles solitary or somewhat 
fascicled, axillary, from the older branches (5 to 6 mm in 
_ diameter or more) below the leaves, densely ferruginous-villous, 
2 to 3 cm long, branched from the base, rather densely many- 
flowered. Flowers yellowish, their pedicels 1.5 to 2 mm long, 
the bracteoles elliptic-ovate, concave, 2.5 to 3 mm long, the ped- 
icels, bracteoles and calyces very densely ferruginous-pubes-
