ORCHIDACEiE 



dunculata superantes, usque ad 2 cm. longa?, acuta?, glumacea?. 

 Racemus laxiflorus, flores, 1.5-2 cm. distantes, circiter 2.5 cm. 

 longi, albidi et flavidi. Sepala lateralia oblonga, acuta, leviter at- 

 tenuata usque ad apicem, membranacea in sicco, leviter carinata, 

 2.7 cm. longa, 9-10 mm. lata. Sepal um dorsale simile, ecarina- 

 tum.Petala sepalis angustiora, oblonga, obtusa, leviter, attenuata 

 prope apicem, 2.9 cm. longa, circiter 6 mm. lata. Labellum 12 

 mm. longum, trilobatum, lobi laterales quinta parte breviores, late 

 semicordati, antice rotundati, lobus medius vix unguiculatus, 

 rotundatus, denticulatus, 6 mm. longus, 9 mm. latus, carina? 2, 

 leviter arcuati, convergentes a basi labelli fere ad apicem lobi 

 medii extensa? biseriata?, ex processibus digitiformibus compo- 

 sitis, cannula brevi utrinque addita prope medium lobi medii. 

 Gynostemium curvatum 1.5 cm. longum ad apicem late alatum, 

 minute denticulatum, ovarium nigro-puberulum. 



Aside from the pair of supplementary carina? in the middle 

 lobe the labellum is distinctly bicarinate. The median nerve is per- 

 haps thickened, but it is free from verrucose projections. The 

 lateral carina? are biseriate, that is, grooved with the edges of 

 the groove broken up rather regularly into short blunt teeth or 

 digitate processes. Ccelogyne palawanense is perhaps nearer to 

 C. Swaniana than to any other described species, but the form 

 of the middle lobe and the bicarinate disc are distinguishing 

 characteristics. In the specimens from which my description 

 was taken the flower shoot was much shorter than the leaves. 



Palawan, Mount Capoas, E. D. Merrill 9499, April 21, 1913, 1000 

 meters altitude. Flower white, lateral lobes of the labellum with yellow 

 lines inside, middle lobe yellow within.
