ORCHIDACEiE 



subelliptica, obtusa, vix 2 mm. longa, circiter .75 mm. lata, uni- 

 nervia. Labellum trilobatum, albidum, saccatum; lobi laterales 

 obtusi ; lobus medius orbicularis, 1 mm. longus, incrassatus. Saccus 

 1.5 mm. longus, ad apicem inflatus et leviter trilobatus, superne 

 dilatatus. Gynostemium breve, antice utroque in processum 

 subulatum productum, superne dilatatum. 



The structure of the gynostemium resembles that of Schcenor- 



chis paniculata Bl. The sac of the labellum is about 1 mm. wide 



at the dilated tip ; in general outline it is not unlike the sac of 



Pomatocalpa spicatum Breda as represented in Ann. Bot. Gard. 



Calc. 5 : t. 84. The sepals are directed forward. The lateral lobes 



of the labellum are erect, rounded, as high as the gynostemium, 



and in front form an acute angle where they join the middle lobe. 



The middle lobe appears to have been slightly conduplicate when 



fresh. The type consists of a single plant. I have not seen any 



other material.
