PTEROSPERMUM ELMERI sp. nov. 
Arbor plus minusve stellato-pubescens ; foliis obliquis, ovatis 
vel oblongo-ovatis, subcoriaceis, 7 ad 10 cm longis, basi rotun- 
datis, subpeltatis, apice breviter acute acuminatis, in siccitate 
supra nigricantibus, glabrescentibus, subtus densissime fusco- 
stellato-pubescentibus ; floribus racemosis, bracteolis profunde 
tripartitis, segmentis lineari-lanceolatis ; sepalis circiter 3 cm 
longis. 
A tree, all parts more or less stellate-pubescent, the branchlets, 
infloi-escence, sepals, and lower surface of the leaves very densely 
so. Branches reddish-brown, terete, ultimately glabrous, the 
younger ones densely brown-stellate-pubescent. Leaves subco- 
riaceous, entire, strongly oblique, ovate to oblong-ovate, 7 to 10 
cm long, 3.5 to 4.5 cm. wide, the wider side of the leaf more than 
twice wider than the narrower one, the base rounded, subpeltate, 
the petiole inserted 2 to 4 mm from the margin, the apex shortly 
and sharply acuminate, upper surface, when dry, black or nearly 
so, somewhat covered with deciduous, brown, stellate hairs, ulti- 
mately glabrous or nearly so, the lower surface very densely 
brown-stellate-pubescent ; lateral nerves 4 or 5 on each side of the 
midrib; petioles densely pubescent, about 3 mm long. Racemes 
terminal and in the upper axils, few-flowered, short; pedicels 2.5 
cm long or less, each with several bracteoles which are cleft 
nearly to the base into three linear, acuminate, 8 to 12 mm long 
lobes. Sepals 3 cm long, about 3 mm wide, externally densely 
stellate-pubescent with brown hairs, internally densely grayish- 
pubescent. Petals about 3 cm long, 8 mm wide. Sterile sta- 
mens 2 cm long, the fertile ones, including the linear 7 mm long 
anthers, 2 cm in length. Ovary densely brown-stellate-pubescent. 
Mindanao, District of Davao, Todaya (Mount Apo) Elmer 11928, Oc- 
tober, 1909, distributed as Pterospermum obliquum Blanco. 
A species manifestly very closely allied to P. subpeltatum Merr., differing 
in its some-what smaller, fewer nerved leaves and in its shorter sepals. 
PTEROSPERMUM LONGIPES sp. nov. 
Arbor circiter 10 m alta, ramulis subtus foliis inflorescentiisque 
dense albido^ vel subfusco-tomentosis ; foliis oblongo-ovatis, 
subcoriaceis, leviter obliquis, usque ad 8 cm longis, integris, 
acuminatis, basi rotundatis vel subtruncatis vix cordatis, supra 
glabris, subtus albido- vel subfusco-tomentosis; floribus panicu- 
latis, long pedicellatis, sepalis circiter 5 cm longis.
