ORCHIDACEiE 



multis ad margines radiorum instar patentibus. Carinae duae 

 longae humiles papillis digitatis permultis e basi labelli ad lobum 

 medium decurrunt; utrinque in basi cannula similis perbrevis. 

 Gynostemium clavatum, arcuatum, in parte superiore alatum; 

 ala rotundata, obtuse dentata. Rostellum parvum, reflexum. 

 Clinandrium conspicuum, ovatum, reflexum. 



Roots few, stout, rigid, about 3 mm. thick, densely clothed 

 with brown tomentum. Rhizome stout, woody, clothed with 

 sheaths that become fibrous. Pseudobulb in dried specimens 

 ±6 cm. long, 1.4 cm. wide at the base, diphyllous, slender cylin- 

 dric, oblique, sulcate, brownish-yellow. Leaves up to 31 cm. long, 

 2.7 cm. broad, linear to oblong-linear, long acuminate, gradually 

 narrowed below, more or less plicate, prominently and about 

 equally five-nerved, the nerves especially conspicuous beneath. 

 Petiole up to 8 cm. long, sulcate. Inflorescence synanthous. Pe- 

 duncle approximate to the pseudobulb, from a decumbent base 

 first ascending then arcuate-flexuous; portion up to the inflores- 

 cence ±12 cm. tall, nearly or quite invested by loosely imbricating 

 ovate to narrowly lanceolate tubular sheaths. Rachis up to 20 cm. 

 long, flexuous-arcuate, subglabrous. Bracts ±3 cm. long, 1.7 cm. 

 broad, persistent, ovate-oblong, broadly rounded, acute, scarious, 

 rigidly nervose, shorter than or surpassing the pedicellate ovary, 

 in development spreading-reflexed, more or less concave. Pe- 

 dicellate ovary 2 cm. or more long, the ovary closely lepidote. 

 Flowers about 6 cm. across when spread out, up to fifteen, si- 

 multaneous, 1.2-1.5 cm. distant, distichously spreading, showy. 

 Sepals somewhat concave at the base, seven- to nine-nerved. 

 Lateral sepals about 3.2 cm. long, 1 cm. wide, linear-oblong, 

 more or less oblique especially at the rounded acute apex, cari- 

 nate, sulcate. Dorsal sepal ±3.2 cm. long, 9.5 mm. broad, narrowly 

 lance-oblong, narrowed to a truncated apex, somewhat carinate.
