SAURAUIA PLATYPHYLLA sp. nov. 
Frutex, ramulis junioribus dense, patule, tenuiter setosis, setae 
usque ad 1 cm longae; foliis elliptico-obovatis, coriaceis, usque 
ad 40 cm longis et 20 cm latis, supra ad costa, subtus ad costa 
nervisque setis paucis longis patulis tenuibus instructis, apice 
breviter acuminatis, basi acutis, margine perspicue attenuato- 
serratis, nervis utrinque circiter 30, patulis, curvatis, utrinque 
valde prominentibus ; floribus caulinis, dense fasciculatis, tenui- 
ter pedicellatis, e tuberculis dense setosis ; sepalis subaequalibus, 
binis exterioribus breviter acuminatis, interioribus rotundatis, 
obovatis, omnibus glabris ; fructibus glabris ; stylis 3, liberis. 
A shrub, the young branchlets densely covered with spreading, 
slender, curved, attenuate, pale-brownish setae up to 1 cm in 
length, with similar scattered setae on the midrib on both sur- 
faces, the nerves beneath, and the petioles. Branches thick- 
ened. Leaves elliptic-obovate, coriaceous, up to 40 cm long and 
20 cm wide, brownish-olivaceous on the upper surface, paler 
beneath, the apex shortly acuminate, the base acute, margins 
conspicuously serrate, the teeth mostly attenuate info slender 
curved setae ; lateral nerves about 30 on each side of the midrib, 
spreading, curved, arched-anastomosing near the margin, very 
prominent on both surfaces, the reticulations prominent, sub- 
parallel; petioles stout, setose, about 3 cm long. Flowers fas- 
cicled, cauline, from densely setose tubercles, usually crowded, 
their pedicels 2.5 to 3.5 cm long, with short, scattered, curved 
setae and usually with two or three oblong-lanceolate, glabrous, 
2.5 to 4.5 mm long bracts below the middle. Sepals subequal, 
glabrous, about 7 mm long, the exterior two shortly acuminate, 
subelliptic, the interior three obovate, rounded. Fruits glabrous, 
globose ; styles 3, free, at least 2 mm in length. 
British North Borneo, Mount Kinabalu, Kiau, Mrs. Clemens 9999, 
November 2, 1915, “a small Saurauia near streams with green cauline 
fruits.” 
This species is remarkable for its unusually large leaves, its slender, 
spreading, curved, attenuate setae, and its cauline fascicled inflorescences; 
by these characters it is readily distinguished from its congeners. It 
does not appear to be closely allied to any previously described form.
