ON THE FLORA OF BORNEO. 109 



margine recurvatis, supra glabris, subtus plus minusve lepidoto- 

 glandulosis, nervis utrinque circiter 8, subpatulis, prominen- 

 tibus, anastomosantibus, retieulo laxo; floribus hypocrateri- 

 formibus, extus cum peclicellis distincte pubescentibus ; tubo 

 cylindrieo, circiter 2 cm. longo, lobis obovatis, rotundatis, cir- 

 citer 12 mm. diametro; filamentis basi villosis; ovario oblongo, 

 dense pubescente, stylo glabro. 



A shrub or small tree, the branches and branchlets terete, 

 grayish or brownish, the former glabrous, the latter with 

 numerous, subdeciduous, dark-brown scales. Leaves verticil- 

 late, usually in threes, thickly coriaceous, elliptic to oblong- 

 elliptic, 8 to 12 cm. long, 4 to 5.5 cm. wide, subequally 

 narrowed to the acute or obtuse base and to the blunt or 

 obscurely and broadly blunt-acuminate apex, the upper sur- 

 face olivaceous, slightly shining, the lower pale-brownish, with 

 numerous, small, dark-brown, scattered scales sunk in minute 

 pits; midrib very prominent on the lower surface, impressed 

 on the upper surface; lateral nerves about 8 on each side of 

 the midrib, spreading, somewhat curved-anastomosing, very 

 prominent on the lower surface, the reticulations lax, pro- 

 minent; petioles, when young, lepidote, in age glabrous, stout, 

 1 to 1.5 cm. long. Heads with about six, pink-purple, ap- 

 parently nodding, pubescent flowers, the pedicels about 2.5 

 cm. long, rather densely pubescent with short, spreading, pale 

 hairs. Calyx disk-like, about 2.5 mm. in diameter. Corolla- 

 tube cylindric, about 2 cm. long, 8 mm. wide when flattened, 

 uniformly and prominently pubescent with short, pale, spread- 

 ing hairs as are the lobes on the back, the lobes obovate or 

 reniform-obovate, about 12 mm. in diameter, broadly rounded. 

 Stamens 10 ; filaments densely pubescent in the lower 6 mm., 

 otherwise glabrous ; anthers oblong, 3 mm. long. Ovary dense- 

 ly pale-pubescent, oblong, about 5 mm. long; style nearly 2 

 cm. long, glabrous. 



British North Borneo, Mount Kinabalu, Marai Parai 

 Spur, Clemens 10892, November 22, 1915, altitude probably 

 about 2400 meters. 



A species well characterized by its salver-shaped, pubes- 

 cent flowers, pubescent pedicels, lepidote branchlets, and thick- 

 ly coriaceous, verticillate leaves which are rather prominently 

 lepidote-glandular on the lower surface, the scattered, small, 

 dark-brown scales being sunk in minute pits. 



Rhododendron obscurinervium, sp. nov. 



Frutex vel arbor partibus junioribus foliisque subtus parce 

 castaneo-lepidotis exceptis glaber; foliis pseudoverticillatis, 

 coriaceis, lanceolatis vel anguste lanceolatis, usque ad 20 cm. 

 longis et 3.3 cm. latis, utrinque angustatis, basi acutis, apice 

 tenuiter acute acuminatis, in siccitate brunneis, nervis utrin- 

 que circiter 18, supra obscuris, subtus obsoletis vel subobsoletis ;
