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 

 tlie 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.
