Var. oMPHALOIDES, Parish.—Labellum rotundatum obtusum. 
Moulmein, Parish! 
This apparently common plant varies very much in the shape of 
the lip, which is typically ovate with a bifid apex ; but the amount 
of fission varies greatly. The auricles too sometimes overlap be- 
hind the column and sometimes do not touch each other. In 
the variety omphaloides the lip is so rounded that, as the auricles 
meet behind, the column appeurs to emerge from the centre of a 
circular lip. In colour the flowers vary from “ chestnut-red’” 
(Hooker) to green, tinted, especially at the base of sepals, petals, 
and lip, with purplish.
