6. THELYMITRA, Forst. 
Terrestrial herbs, usually glabrous. Root of oblong or ovoid 
tubers. Leaf solitary, linear or lanceolate, often thick and fleshy 
but not terete; empty sheathing bracts 1 or 2 along the stem. 
Flowers few or many in a terminal racéme, sometimes reduced to 
one. Sepals and petals similar 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 30 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 Ixia 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 fol- 
lowing 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 at least three additional forms, but they cannot be safely described until more 
complete material is available. 
A, Cucullaria. Colwmn-wing extending behind the anther and usually over- 
topping it, hood-shaped, variously lobed or fringed, the lateral lobes tipped 
with a dense brush of cilia.

the back between the lateral lobes .. nt .. 1. T. iatoides. 
Column-wing with a broad entire or emarginate lobe

shaped lobe between the lateral lobes, which are longer
