 deltoid-orbicular , thus about as broad as long, reaching but slightlj 

 beyond the basc of the calyx ; upper (through resupination lower) calyx- 

 lobe rhomboid, or lanceolar-ovate, lower (through resupination upper) two 

 disconnected, all dark-purplish, but at and towards the margin greenish ; 

 paired petals eliiptic-lanceolar, somewhat or hardly shorter than the calyx-

 slightly raised on a broad interstice, its main portion cuneate-orbicular, 

 much incurved, but at the upper end again beut outward, greenish and 

 upwards purplish or whitish, jjrovided at the commencement of the terminal 

 portion with a conspicuous usually dark-green almost semicircular some-
