ORCHIDACE^ 



0.5 mm. in diameter, together with the pseudobulbs clothed with 

 tubular acute or obtuse bracts, which, when dry, are conspicu- 

 ously many-nerved. Peduncle wiry, shorter than the leaves or 

 exceeding them, 1-1.5 dm. long, persistent on the mature and 

 leafless pseudobulbs. Raceme erect, loosely flowered, ± 4 cm. long. 

 Floral bracts 4 mm. long, cymbiform, acute, the lowermost one 

 empty, embracing the foot of the rhachis, dilated, truncate-aris- 

 tate. Flowers 6 mm. across, orange-red when dry, cinnabar when 

 fresh, according to the collector's observations. Lateral sejjals 

 oblique, 3-3.5 mm. long, 3 mm. wide, broadly ovate, obtuse, 

 3-nerved. Upper sepal about 4 mm. long, 2.5 mm. wide, rhombic- 

 lanceolate to ovate-lanceolate. Petals rhombic-cuneate, at the 

 rounded apex acuminate or subcaudate, 2.5 mm. long, 2.75 mm. 

 wide, 3-nerved. Labelluin 3-lobed; middle lobe hastate, acute, 

 somewhat fleshy, 2 ilim. long, concave and bicallose at base ; calli 

 nipple-like, inflexed ; latei'al lobes diaphanous, oblong, obtuse or 

 subacute, relatively small, 1 mm. long. Column typical of the 

 section. 



My description is based on a specimen in the United States 

 National Herbarium, numbered 461, which A. Loher collected 

 in Benguet, Luzon. This specimen is a duplicate of the one 

 on which Pfitzer established DendrocMlum ci?inaba?ijiu7?i. In 

 Fascicle ii of Orchidace^ it was stated that neither the de- 

 scription nor the figure published by Pfitzer and Kriinzlin is re- 

 liable, both conveying an erroneous and a misleading impression. 

 The position assigned to the species is quite anomalous and is ex- 

 plicable only on the assumption that Pfitzer mistook the lateral 

 lobes of the labellum for stelidia arising from the base of the 

 minute column. In his figure prepared to illustrate Z). cinnaba- 

 rinum the lateral lobes of the labellum are not shown, nor is the
