ated at both ends and furnished with a conspicuous median nerve. 

 The bidentate, abbreviated arms of the column are characteristic.

 sicco apparens. Petiolus ad basim dilatatus, vaginans, purpu- 

 reus. Pedunculus elongatus gracilis circiter 1 dm. longus, bracteis 

 linearibus ± 5 mm. longis. Racemus gracilis, circiter 5 cm. 

 longus. Bracteae inflorescentiae lineares, dependentes, purpu- 

 reae, color non in specimene sicco apparens. Sepala lateralia 3 

 mm. longa, 1.5 mm. lata, oblongi-elliptica, convexa, obtusa. 

 Sepalum dorsale simile. Petala linearia, 2.5 mm. longa. Label- 

 lum sagittatum, auriculis longe triangulis obtusis 1.5 mm. longis. 

 Lobus medius elongatus, anguste oblongus, bifidus, circiter 1.5 

 mm. longus, lobi laterales bidentati. Gynostemium 1 mm.

This species is well characterized by the distichous leaves, 

 about 9 in number, described by Mr. Elmer as flat, horizontal, 

 coarsely corrugated, submembranaceous, dull green above, light 

 purple bentath. The flowers are described as purplish and yellow- 

 with green pedicel and purple bracts. The labellum suggests that of 

 M. dentata Ames (Orchidaceae 11:126, fig.) from which it differs in 

 the longer auricles, bidentate lateral lobes and the deeply bifid, 

 slender middle lobe. The general form of the labellum is sagittate.
