ON THE FLORA OF BORNEO. 103 



rather distinct on the lower surface, the lateral nerves 2 or 3 

 on each side of the midrib, mostly basal or sub-basal, sharply 

 ascending, slender, anastomosing, not prominent; petioles 

 about 1 mm. long. Racemes solitary in the upper axils, 

 glabrous or very obscurely pubescent, 1.5 to 3 cm. long, few- 

 flowered, rarely more than 6 flowers in a raceme, the pedicels 

 about 5 nun. long, spreading or somewhat recurved, slightly 

 elongated in fruit. Flowers white, about 1 cm. long, cylindric 

 or subcylindric. Calyx somewhat turbinate, about 3 mm. 

 long, very slightly pubescent, the teeth 5, orbicular-ovate, 

 rounded, about 1 mm. long. Corolla glabrous externally, 

 somewhat villous inside, 8 to 9 mm. long, slightly inflated, 

 slightly narrowed upward, the lobes 5, recurved, orbicular or 

 orbicular-ovate, rounded, about 1 mm. long. Stamens 10 ; 

 filaments villous, about 2.5 mm. long; anthers about 1 mm. 

 long, minutely 2-awned on the back, the appendages tubular, 

 short, broad. Top of the ovary densely villous; style about 8 

 mm. long, villous except the upper one-fourth. Immature 

 fruits ovoid, about 1 mm. long, glabrous except the tip inside 

 the calyx-teeth which is densely villous. 



Sarawak, Mount Santubong, Native collector 2235 

 (type) ; Mt. Poe, Foxworthy 20k, May, 1908, summit altitude 

 1300 m.; Dutch Borneo, G. Kelam, Hallier 2J/.76, doubtfully 

 identified as Vaccinium ouxifolium Hook. f. as a variety; 

 British North Borneo, Mount Kinabalu, Gurulau Spur, 

 Clemens s.n., November 8, 1915, sterile. 



The specimens resemble Vaccinium varingaefolium, Miq. 

 and V. lucidum, Miq., in many features, but the species is dis- 

 tinguished by its vegetative and floral characters. It is ap- 

 parently most closely allied to the Philippine Vaccinium pala- 

 ivanense, Merr., but has smaller, diverently shaped leaves and 

 somewhat larger flowers. It is not closely allied to Vaccinium 

 ouxifolium, Hook, f., of which I have excellnt specimens from 

 the type locality, Clemens 10665. 



Vaccinium caudatifolium, sp. nov. 



Frutex vel arbor partibus junioribus inflorescentiisque 

 exceptis glaber; foliis coriaceis, lanceolatis, vel oblongo-lanceo- 

 latis, usque ad 15 cm. longis, integris, in siccitate olivaceis 

 vel brunneo-olivaceis, utrmque nitidis, laevibus, concoloribus, 

 apice tenuissime caudato-acuminatis, basi acutis, nervis utrin- 

 que 4 vel 5, adscendentibus, tenuissimis, utrinque obscuris; 

 racemis axillaribus, solitariis vel fasciculatis, tenuibus, usque 

 ad 5 cm. longis, laxifloris ; floribus minutis, circiter 2.5 mm. 

 longis, ellipsoideis, 5-angulatis ; antheris dorso minute 2- 

 aristatis, appendicibus tenuissimis, circiter 2 mm. longis. 



A shrub or tree, the bran chiefs and inflorescence some- 

 what pubescent with short brownish hairs, otherwise glabrous. 

 Branches slender, terete, reddish-brown, sparingly lenticellate,
