cm wide, the apex broadly rounded to broadly and shortly obtuse- 
acuminate, base somewhat decurrent-acuminate, margins crenu- 
late or crenulate-denticulate, the upper surface smooth and 
shining, dark-olivaceous when dry, the lower surface paler, 
brown, obscurely glandular-maculate; lateral nerves about 15 
on each side of the midrib, slender, distinct, anastomosing, more 
prominent on the lower than on the upper surface; petioles 5 to 7 
mm long. Flowers 5-merous, axillary, solitary, the peduncles gla- 
brous, curved, stout, about 2 cm long. Calyx glabrous, the lobes 
orbicular to orbicular-reniform, broadly rounded, coriaceous, 
concave, about 7 mm long, 6 to 8 mm wide, margins sometimes 
slightly ciliate, not glandular. Petals obovate, broadly rounded, 
about 1.8 cm long, 1.3 cm wide, the exposed median portions of 
the back rather densely appressed-pubescent with pale hairs 
otherwise glabrous. Stamens about 50; filaments 4 to 8 mm 
long, slightly hirsute; anthers oblong-lanceolate, acute or acumi- 
nate, slightly hirsute, 4 mm long. Ovary ovoid, glabrous, 
narrowed upward into the glabrous style, 5-celled, the ovules 
indefinite. 
Luzon, Province of Rizal, Oriud, Loher 560k , December, 1905. 
A characteristic species, apparently allied to Adinandra lamponga Miq., 
but differing in many details. It is well characterized, among the Phil- 
ippine forms, by being nearly glabrous, the only pubescent parts being the 
very small vegetative buds, the median parts of the petals, outside, and the 
stamens. 
ADINANDRA M ACGREGORII sp. nov. 
Arbor circiter 15 m alta, plus minusve villosa; foliis coriaceis, 
ellipticis ad oblongo-ellipticis, usque ad 10 cm lDngis, supra 
nitidis, gabris, subtus adpresse villosis, basi acutis ad subro- 
tundatis, apice breviter acuminatis, margine distincte minute- 
que glanduloso-denticulatis, nervis utrinque 12 ad 15, distinctis; 
sepalis extus villosis, petalis late ellipticis, rotundatis, circiter 
1.4 cm longis; staminibus 35, antheris parce villosis; ovario 
4-loculare, dense pallide villoso. 
A tree about 15 m in height, the buds and growing branchlets 
very densely appressed-villous with pale hairs, the petioles, lower 
surfaces of the leaves, and flowers less densely villous. Branches 
terete, grayish, glabrous. Leaves coriaceous, elliptic to oblong- 
elliptic, 5 to 10 cm long, 2.5 to 4 cm wide, apex shortly acuminate, 
base somewhat rounded to somewhat acute, margins very 
minutely glandular-denticulate, the upper surface olivaceous 
when dry, glabrous and shining, the lower much paler, with 
scattered, more or less appressed, pale hairs; lateral nerves
