similar to those of A. tridens (Lindl.) Schltr. but the 
anticous margins are not quite so dilated as in that spe- 
cies. In none of the species so far described is the spur 
so swollen as in A. breviloba.

(Schlitr.) Schltr. petalis liberis anguste triangularibus, 
labelli lobis lateralibus brevissimis rotundatis, pollinii 
viscidio uno communi distinguitur.

medium anguste lanceolato-ellipticum, acutum, circiter 
4mm. longum, 1 mm. latum; sepala lateralia parallela et 
porrecta, ex ungue angusto curvatim lanceolata (vel an-
