late, acuminate, indistinctly three-lobed, lateral lobes incurved, 
middle lobe lobed and crenulated at the margin: the disc bears 
(in_our plants) three membranous plates, which become lobed 
and undulated in the middle lobe of the labellum. Column

Curr. This singular plant is one of the few epiphytal Orchids 
that are natives of New Holland. They are chiefly found beyond 
the tropic on the eastern coast, in a climate where they often 
endure great drought, some growing on trees fully exposed to 
the sun. They are generally of a rigid, dry habit, and often do 
not thrive well under cultivation in this country. ‘The present 
species is usually imported growing on the smaller branches of 
trees, to which it is firmly fixed by its roots. We find it thrive 
best in a house or pit that receives no artificial heat, except 
sufficient to keep out frost. 7. 8.
