ORCHIDACEM 151 



Pseudobulbs up to 3 cm. long, terete, concealed by distichous 

 chartaceous bracts. Leaves up to 1 dm. long, conduplicate when 

 dry, fleshy, strongly grooved, obtuse. Floral bracts? Peduncle 

 basilar, much exceeded by the leaves, slender, 8-13 mm. long, 

 densely clothed with arachnoideous, whitish, silky hairs. Lateral 

 sepals oblong-lanceolate, 3-nerved, about 4 mm. long, produced at 

 base into a conspicuous mentum covered with densely matted, whitish 

 hairs. Upper sepal similar to the laterals. Petals linear-lanceo- 

 late, acute, much narrower and shorter than the sepals, about 

 3 mm. long, less than 1 mm. wide. Labellum 4-4.5 mm. long, 

 antrorse, 3-nerved ; expanded portion subquadrate-oblanceolate, 

 acuminate; the acuminate apical portion 1-1.5 mm. long; the 

 thickened, subacute, quadrate portion 1.9-3 mm. long, 1.9 mm. 

 wide ; claw cuneate. Capsule 7 mm. long, ellipsoidal-oblong. 



High on trees, alt. 350 ft., Lamao River, Mt. Mariveles, Prov. 

 Bataan, central Luzon, January 20, 1904, R. S. Williams (no. 

 506). — On trees, very common, Surigao, Prov. Surigao, Minda- 

 nao, January 6, 1906, F. H. Bolster (no. 215). — Flowers white 

 with few purple markings, Bosoboso, Prov. Rizal, Luzon, April 23, 

 1907, Maximo Ramos (no. 3017). 



Reichenbach's account of the labellum describes well the la- 

 bellum of the plants collected by Williams and Bolster, although 

 the styliform processes were not observed. Regarding these Rei- 

 chenbach was uncertain, and as the material on which he worked 

 was not in good condition, he may have been mistaken concerning 

 them. The specimens gathered by Bolster match well in habit the 

 specimens collected by the Wilkes expedition.
