1584 Leaflets of Philippine Botany [Vol. V, Art 77 



Leaves 2 — 3 cm. apart, petiolate. Lamina ±1.5 dm. long, 

 1.5 — 1.8 cm. wide, tapering gradually to both ends, chartaceous 

 when dry, coriaceous in living specimens, many nerved with a 

 conspicuous mid-nerve, apex sharp pointed. Petals 2 — 5 cm. 

 long, slender. Scape about equalling the leaf in length, up to 

 1.5 dm. long with several lanceolate and acute bracts below the 

 inflorescence. Raceme about 12-'flowered, nearly 1 dm. long. 

 Pedicel and ovary short, shorter than the lanceolate bracts. 

 Bracts of the inflorescence about 5 mm. long. Lateral sepals 7 

 mm. long, about 3 mm. wide near the base. Upper sepal equal- 

 ling the laterals but narrower. Petals 3.5 mm. long, lanceolate, 

 abruptly contracted at about the middle into an acuminate, 

 cellular-ciliate tip, 1-nerved. Labellum lingulate, about 4 mm. 

 long, sharply deflexed at about the middle, margin erect at base, 

 margin at the apex cellular-ciliate and long ciliate; at the point 

 where the apical half is deflexed two inconspicuous intra-marginal 

 lamellae are situated. 



.\lthough a near relative of D. dasypetalum, B. lancipetalum , 

 etc., B. lancifolium is easily recognized by its acuminate, acute 

 leaves.
