Luzon, Ilocos Norte Province, between Bangui and Claveria, 
Bur. Sci. 33034' Ramos, August 21, 1918, in forests near the sea 
at low altitudes. 
This species is remarkable for its exceedingly large leaves, 
which attain at least 1 meter in length. It belongs in the group 
with Dillenia suffruticosa Grielf. and like that species has a por- 
tion of the upper surface of the decurrent basal part of the 
lamina conduplicate and supplied with a modified, apparently ab- 
sorbent, epidermal tissue. Among the Philippine species it is 
most closely allied to Dillenia papyracea Merr., of Basilan, from 
which it is readily distinguished by its very much larger leaves, 
softly pubescent inflorescences and sepals, and fewer carpels. 
SAURAUIA Willdenow 
SAURAUIA SANTOSII sp. nov. 
Arbor 7 ad 9 m alta, S', eleganti affinis, differt floribus major- 
ibus, 1.5 ad 2 cm diametro, confertis, foliis subtus densissime 
fulvo-ferrugineo-lanatis. 
A tree, 7 to 9 m high, the branches brown, setose, and densely 
ferruginous-tomentose, the setae comparatively few, filiform, 4 
to 7 mm in length, ascending. Leaves thickly coriaceous, rigid, 
oblong, 13 to 18 cm long, 5.5 to 7 cm wide, obtuse, the base round- 
ed, cordate, often somewhat oblique, the margins with small, 
thick, rounded teeth, these often terminating in filiform, decid- 
uous setae, the upper surface brown, glabrous, shining, rugose- 
pustulate, the nerves impressed, the lower surface very densely 
fulvous-ferruginous-lanate, the indumentum covering the whole 
surface, midrib, and nerves, the midrib and nerves also with few, 
scattered, filiform setae; lateral nerves 25 to 30, prominent, 
projecting; petioles 2 to 4 cm long, setose and tomentose. In- 
florescences axillary, long-peduncled, cymose, the flowers crowd- 
ed, the peduncles 10 to 12 cm long, densely tomentose and rather 
sparingly setose, the cymes compact, 4 to 5 cm in diameter. 
Flowers white, 1.5 to 2 cm in diameter, their pedicels up to 5 mm 
in length, setose and tomentose. Sepals broadly ovate, obtuse 
or rounded, 5 mm in diameter, the outer ones thiqkly coriaceous, 
densely villous and setose, the setae slender, up to 2 mm in 
length, the inner ones thinner, rather sparingly villous and not 
setose. Petals oblong-obovate, rounded, about 11 mm long and 
7 mm wide. Ovary glabrous; styles 2, free to the base, 4 mm 
long.
