SAURAUI A HETEROSEPALA sp. nov. 
Frutex, ramulis junioribus plus minusve adpresse squamulosis; 
foliis oblongis ad oblongo-obovatis, usque ad 24 cm longis, acumi- 
natis, basi acutis, junioribus subtus ad costa nervisque parcissime 
adpresse squamulosis, vetustioribus glabris, laevis, nitidis, oliva- 
ceis, margine minute incurvato-serrulatis, nervis utrinque 10 ad 
13, perspicuis ; floribus e axillis defoliatis et caulinis, superioribus 
solitariis, tenuiter pedunculatis, ebracteolatis, inferioribus depau- 
perato-cymosis, bracteolatis ; sepalis glabris, binis exterioribus 
latissime orbiculato-ovatis, rotundatis, circiter 8 mm longis et 
latis, interioribus contorto-imbricatis, distincte longioribus ; 
ovario glabro, stylis 3, infra connatis. 
A shrub, ultimately glabrous or nearly so, the young branchlets 
with few, scattered, irregular, ovate to suborbicular, appressed, 
pale-brownish scales, with similar ones on the midrib and nerves 
of the younger leaves and on the peduncles, the older leaves gla- 
brous. Leaves oblong to oblong-obovate, 10 to 24 cm long, 4 to 9 
cm wide, base acute, apex acuminate, margins minutely incurved- 
serrate, olivaceous and shining on both surfaces when dry, 
chartaceous; lateral nerves 10 to 13 on each side of the midrib, 
prominent, the reticulations slender, close, subparallel; petioles 
1 to 2 cm long, sparingly scaly. Flowers in the axils of fallen 
leaves and from the branches and trunks, the upper ones solitary, 
ebracteolate, the lower ones in depauperate, few-flowered cymes, 
the pedicels up to 2.5 cm long. Sepals distinctly unequal, all 
glabrous, rounded, the outer two broadly orbicular-ovate, about 
8 mm long and wide, the inner three twisted-imbricate, about 
10 mm long and 9 mm wide. Ovary glabrous; styles united 
for the lower 3 mm, the arms 3, about 4 mm in length. Bracts 
on the lower inflorescences oblong-lanceolate to oblanceolate, 
acute to acuminate, glabrous, 5 to 8 mm long. 
British North Borneo, Mount Kinabalu, Khota Balud to Kibayo, Mrs. 
Clemens 9812, October 28, 1915, the fruit green. 
The alliance of this species is apparently with the Javan Saurauia 
leprosa Korth., from which it is readily distinguished by its inflorescences 
and floral characters.
