308 ORCHIDACEAE. [ Thelymitra. 
and equal or nearly so, spreading. Lip similar to the petals, quite free 
from the column at the base. Column short, erect, broadly 2-winged ; 
the wings either produced behind the anther with a variously lobed or 
fringed or rarely entire margin, or with 2 prominent lateral lobes as long 
or longer than the anther; at the base the wings extend between the 
column and the lip and are united. Anther in front of the produced wing 
of the column or between its lateral lobes, erect, 2-celled; connective 
often produced ; pollinia 2 in each cell, friable. 
A genus of probably over 40 species, mostly natives of Australia and New Zealand, 
one species only being found in New Caledonia, and two in the Malay Archipelago. It 
is remarkable from the lip being quite free from the column and resembling the petals 
and sepals, so that the perianth has little of the irregular appearance of an orchid, but 
rather resembles that of an Jwvia or Sisyrinchium. The New Zealand species are much 
alike in habit and general appearance, and in most cases cannot be distinguished from 
one another when out of flower, or when dried. Even when in the flowering state 
they require careful study before their differential characters can be understood. The 
following analysis is in several respects imperfect, but is the best that I can offer in 
the present state of our knowledge. I have in my herbarium specimens of several 
additional forms, but they cannot be safely described until more complete material 
is available.
