The colours of the flowers being deep orange-yellow, 
mottled with deep brown spots, the aspect of this species 
is rather handsome. Fig. 1. represents the appearance of 
the lip separated from the column, and especially of the 
double callus at the base of its middle lobe. Fig. 2. shews 
the face of the column with the bases of the sepals and petals. 
Fig. 3. is a view of the double strap, connecting the pollen 
masses to the gland. Fig. 4, shews the anther removed from 
the column, and viewed in front.
