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. 



British North Borneo, Kalabakan, Villamil 222, September 26, 1916, 

 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.
