This species, like Saurauia myrmecoidea Merr., is apparently allied to 
Saurauia horrida Hook, f., from which it is easily distinguished by its midrib 
being setose on the upper surface and by its cauline fascicled cymes 
(attachment of the inflorescences not indicated in Hooker’s diagnosis, but 
presumably axillary) . The more numerous lateral nerves, glabrous upper 
surface of the leaves, other than the midrib, and the cauline cymes distin- 
guish it from S. myrmecoidea Merr. 
SAURAUIA BORNEENSIS sp. nov. 
Frutex circiter 2.5 m altus, ramulis junioribus petiolisque 
densissime cinnamomeo-lanato-tomentosis atque setis paucis 
curvato-adpressis instructis; foliis late oblongo-oblanceolatis, 
usque ad 40 cm longis, chartaceis ad subcoriaceis, supra brunneis, 
laevis, glabris, subtus pallidioribus et plus minusve decidue cin- 
namomeo-lanatis, apice acutis, deorsom gradatim angustatis, basi 
obtusis, margine cornuto-serratis, nervis utrinque circiter 20, 
perspicuis; floribus axillaribus, paucis, fasciculatis, pedicellatis, 
sepalis leviter inaequalibus, extus leviter pubescentibus ; ovario 
pubescens ; stylis 3, liberis. 
A shrub about 2.5 m high, the branchlets and petioles densely 
covered with a cinnamomeous lanate-tomentose indumentum and 
with few, scattered, curved-appressed setae, the lower surface 
of the leaves also cinnamomeous-lanate, the indumentum conspic- 
uous along the midrib and nerves, somewhat deciduous. Leaves 
broadly oblong-oblanceolate, chartaceous to subcoriaceous, 30 
to 40 cm long, 8 to 12 cm wide, the upper surface smooth, glab- 
rous, brown, shining, the lower paler, the apex acuminate, grad- 
ually narrowed from above the middle to the narrow, obtuse 
base, the margins serrate; primary lateral nerves about 20 on 
each side of the midrib, prominent, spreading, curved, anasto- 
mosing, the reticulations slender, not prominent, rather lax; 
petioles 4 to 5 cm long. Flowers white, axillary, fascicled, few, 
their pedicels pubescent, 1 cm long or less. Sepals pubescent, 
unequal, mostly rounded or obtuse, two elliptic, 3.5 mm long, 
three broadly ovate, about 4 mm long. Corolla-lobes oblong- 
elliptic, somewhat retuse, 4.5 mm long. Ovary globose, some- 
what pubescent; styles 3, free, about 3 mm long.

in forests, altitude about 4 meters. 
This characteristic species is readily distinguished by its cinnamomeous- 
lanate indumentum, which on the branchlets and petioles is intermixed with 
curved-appressed, slender setae; its elongated, broadly oblong-oblanceolate 
leaves, which are gradually narrowed below the middle to the narrow but 
obtuse base; and its axillary fascicled flowers. I know of no species that 
is closely allied to it.
