Rootstock creeping, annulate, giving off pendulous stems 

 2-3 ft. long, bearing a few lateral and terminal fusiform 

 pseudobulbs 2-2\ in. long; internodes long, terete, smooth;

 Thvvaites says 'not uncommon in the Central Prov.;' but there are no 

 specimens in Herb. Perad. from either. Fl. August; white, with the lip 

 and mentum yellow.
