108 ON THE FLOKA OF BOENEO. 



British North Borneo, Mount Kinabalu, Marai Parai 

 Spur, Clemens 11027, December 1, 1916, epiphytic. 



A most characteristic species, at once distinguished from 

 all described forms by its very long, narrow, thickly coriaceous 

 leaves. 



Rhododendron, Linnaeus. 



Rhododendron lineare, sp. nov. 



Frutex (forsan epiphyticus), ramulis junioribus et foliis' 

 subtus et floribus perspicue castaneo-lepidotis ; foliis linearibus, 

 3.5 ad 4 cm. longis, 3 ad 5 mm. latis, pseudoverticillatis, ob- 

 tusis, coriaceis, costa prominentibus, nervis reticuloque obso- 

 letis; floribus circiter 2 cm. longis, campanulato-infundibu- 

 liformibus, profuncle 5-lobatis, extus lepidotis. 



A shrub, perhaps epiphytic, strongly characterized by its 

 very narrow, small leaves. Branches slender, terete, glabrous, 

 irregular, the branchlets densely lepidote, the scales dark- 

 brown, prominent. Leaves verticillate or pseudoverticillate, 

 coriaceous, linear, 3.5 to 4 cm. long, 3 to 5 mm. wide, obtuse 

 at both ends, margins somewhat recurved, brownish-olivaceous, 

 shining, the midrib prominent, impressed on the upper surface, 

 the nerves and reticulations wholly obsolete, the lower surface 

 prominently lepidote, the scales occupying small pits; petioles 

 densely lepidote, 1 to 2 mm. long. Mowers terminal, ap- 

 parently each inflorescence with 3 or 4 flowers, their pedicels 

 about 8 mm. long, very densely covered with rather large, 

 round, easily detached, dark-brown scales. Calyx disk-like, 

 small, lepidote. Corolla about 2 cm. long, campanulate-in- 

 fundibuliform, the tube cylindric, about 7 mm. long, external- 

 ly densely brown-lepidote, the lobes elliptic-oblong, about 12 

 mm. long and 7 mm wide, rounded, the median portion in 

 the lower one-half with scattered round scales. Stamens 10: 

 filaments very slender, villous at the base; anthers narrowly 

 oblong, 3 mm. long. Ovary and style about 2 cm. long, very 

 densely lepidote, the scales round, rather large, dark-brown, 

 easily detached, the upper part of the style nearly glabrous. 



Sarawak, without definite localitv, Xative collector 1161

A most characteristic species, at once distinguished from 

 all described forms by its small, linear, very narrow, coriaceous 

 leaves. 



Rhododendron kinabaluense, sp. nov. 



Frutex vel arbor parva; ramulis junioribus plus minusve 

 brunneo-lepidotis ; foliis verticillatis, ellipticis vel oblongo- 

 ellipticis, coriaceis, usque ad 12 cm. longis, apice obtusis vel 

 obscure latissime obtuse acuminatis, basi acutis vel obtusis,
