OX THE FLORA OF BORNEO. 107 



villous, the upper one-fourth glabrous ; anthers oblong, some- 

 what Hexed in the middle, 2 mm. long, the dorsal awns ob- 

 solete, the appendages eylindrie, truncate, about 1 mm. long. 

 Disk prominent, glabrous; style about 9 mm. long, somewhat 

 exserted in anthesis, glabrous. 



Sarawak, Baram, Hose 236, December, 1894. 



The alliance of this species is manifestly with Vaccinium 

 sarawalcense, Merr., in spite of the fact that the anthers are 

 not awned. It differs from V. sarawal-ense, Merr., notably in 

 its more numerous, much more prominent lateral nerves and 

 more prominent reticulations. 



Diplycosia, Blume. 



Diplycosia ensifolia, sp. nov. 



Frutex epiphyticus, noribus parcissime pubescentibus ex- 

 ceptis glaber ; foliis lanceolatis vel lineari-lanceolatis, usque ad 

 20 cm. longis et 1.8 cm. latis, coriaceis, acuminatis, laevibus, 

 basi obtusis vel rotundatis, obscure triplinerviis ; floribus axil- 

 laribus, solitariis vel binis, breviter pedicellatis (pedicello 

 circiter 4 mm. longo) ; uracteis renif ormibus ; calye circiter 

 5 mm. longo, lobis erectis, ovatis, obtusis; corolla ut videtur 

 obovoidea, 5 mm. longa. 



An epiphytic shrub, entirely glabrous except the sparingly 

 pubescent flowers. Branches terete, smooth, dark-colored when 

 dry. Leaves alternate, thickly coriaceous, rigid, lanceolate to 

 linear-lanceolate, olivaceous or pale, usually somewhat shining 

 when dry, smooth, 13 to 20 cm. long, 1.2 to 1.8 cm. vdde, 

 straight or slightly falcate, base rounded or obtuse, obscurely 

 3-plinerved, gradually narrowed upward to the slenderly acu- 

 minate apex, the midrib and on the larger leaves the basal 

 nerves impressed on the upper surface, on smaller leaves the 

 basal nerves obsolete or nearly so, reticulations obsolete ; lateral 

 basal pair of nerves in larger leaves extending nearly to the 

 apex of the leaf as marginal nerves, obsolete on the lower 

 surface ; lower surface with scattered, punctate, dark-colored 

 glands; petioles stout, channeled on the upper surface, up to 

 3 mm. in length. Flowers white tinged with dull lavender, 

 axillary, solitary or in pairs, their pedicels about 4 mm. long, 

 very slightly pubescent, the bracts at the apex of the pedicels 

 two, reniform, rounded, 1.2 mm. long, 2.2 mm. wide, margins 

 obscurely short-ciliate. Calyx-tube somewhat funnel-shaped, 

 the lobes 5, erect, ovate, obtuse, 2 mm. long, their margins 

 obscurely short-ciliate. Corolla, apparently obovoid, glabrous, 

 5 mm. long, the orifice round, about 2 mm. in diameter. 

 Stamens 10 ; filaments glabrous,2 mm. long ; anthers oblong- 

 ovoid, 1.5 mm. long. Ovary globose, glabrous; style 2.5 

 mm. long. Fruit "white" (not seen).
