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 ; fioribus caulinis, dense fasciculatis, tenui- 

 ter pedicellatis, e tuberculis dense setosis ; sepalis subaequalibus, 

 binis exterioribus breviter acuminatis, interioribus rotundatis, 

 obovatis, omnibus glabris ; f ructibus 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 into 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. 



SAURAUIA WINKLERI sp. nov. 



Frutex vel arbor parva, partibus junioribus exceptis glabris, 

 ramulis teretibus, laevis, atro-brunneis, junioribus squamis pau- 

 cis adpressis lanceolatis instructis ; foliis membranaceis ad char- 

 taceis, oblongis, usque ad 14 cm longis, glabris, in siccitate supra 

 castaneis, subtus pallidis, apice tenuiter acute acuminatis, basi
