flowers is usually owing, assumes a regular structure in a 

 few cases, of which this is one of the most striking. In this 

 genus the lip is so much like the other petals, that it is 

 only to be recognized by its position. Thelymitra, Hexisea, 

 Isochilus, and such others as have been previously disco- 

 vered with this character, are so extremely unlike Paxtonia 

 in other respects that it is not worth instituting any com- 

 parison between them.
