 Flores aurantiaci. Sepala reflexa, lanceolata, carinata. Petala 

 reflexa, linearia, sub-acuta. Labellum lanceolatum, acuminatum, 

 8 mm. longum, ad basim callo cucuUato instructum. Columna bre- 

 viuscula, apice incrassata. Anthera sub-quadrata, antice late mar- 

 ginata. 



Roots fibrous, about 1 mm. thick. Pseudobulbs approximate, 

 swollen, 1.5-2 cm. long, concealed by elongated chartaceous bracts, 

 monophyllous. Leaves nervose, linear-oblong, acute, 20-30 cm. 

 long, 12-20 mm. wide, narrowed below, deciduous from an elon- 

 gated persistent base. Scape equalling or exceeding the leaves, 

 strongly winged, compressed, 3-5 mm. wide, 14-33 cm. long, 

 terminal. Raceme 1.5-6 cm. long. Bracts distichous, approxi- 

 mate, conduplicate, carinate, oblong-lanceolate, acute, 9-13 mm. 

 long, deciduous, leaving the naked rhachis somewhat zigzag. 

 Flowers orange-yellow, borne on elongated pedicels which exceed 

 the bracts, few open at a time. Perianth strongly reflexed. Lateral 

 sepals lanceolate, about 10 mm. long, acute, strongly keeled near 

 the apex, margins revolute. Upper sepal narrower, similar. Petals 

 linear, 9 mm. long, sub-acute, 1-nerved, margin revolute. Labellum

 in front of the short claw a cucullate appendage, on either side 

 of which is a rounded protuberance. Column thick, 4.5 mm.

 ellipsoidal capsule, 2 cm. long. 



The plant which I have called Cestichis philipjnneiisis, and 

 which so far as I can ascertain has not heretofore been described,
