chartaceis, oblongo-obovatis ad late oblanceolatis, usque ad 17 cm 
longis, acuminatis, basi angustatis, acutis vel subacutis, nervis 
utrinque circiter 8 ; floribus axillaribus, solitariis vel binis, longe 
pedicellatis, sepalis exterioribus quam 2 interioribus multo 
latioribus ; stylis 3, liberis, 5 mm longis. 
A shrub or small tree, more or less appressed-setose, branches 
terete, glabrous, grayish, the younger ones appressed-setose and 
more or less furfuraceous as are the petioles and pedicels. 
Leaves chartaceous, oblong-obovate to broadly oblanceolate, 9 
to 17 cm long, 3.5 to 5.5 cm wide, apex acuminate, narrowed 
below to the acute or subacute base, the margins more or less 
denticulate or setose-denticulate, the upper surface glabrous ex- 
cept for the sparingly appressed-setose midrib, brownish-oliva- 
ceous, the lower appressed-setose on the midrib and lateral 
nerves with few short setae on the reticulations ; petioles 5 to 12 
mm long, more or less appressed-setose. Flowers solitary or in 
pairs, axillary, their pedicels slender, appressed-setose, 1.5 to 
3 cm long. Exterior three sepals broadly ovate, about 8 mm long, 
7 mm wide, rather densely covered with stout, appressed setae, 
the setae up to 2 mm long, obscurely ciliate, the inner two petaloid, 
narrowly oblong, glabrous, about 8 mm long and 3.5 mm wide. 
Corolla-lobes about 10 mm long, 6 mm wide, oblong-obovate; 
filaments and anthers each about 2.5 mm long. Ovary glabrous ; 
styles three, free, about 5 mm long.

This species, from its floral structure and the position of its flowers, 
is allied to Saurauia samarensis Merr., but is totally different in vegetative 
characters; both have wide, setose outer sepals and very much narrower, 
glabrous or nearly glabrous inner sepals. Cuming 1712, from Samar, 
tentatively referred by Dr. Stapf 1 to Saurauia ferox Korth., represents a 
very closely allied form, but a critical comparison with the Mindanao 
specimens presents several differences. In Cuming’s specimen the lateral 
nerves are about 12 on each side of the midrib instead of 8, the petioles 
are somewhat longer, and the setae on the outer sepals are distinctly 
spreading and minutely ciliate. Neither specimen can be referred to 
Korthal’s species, as the latter has peduncled, cymose inflorescences.
