This plant would thus seem to be variable, and to have a 

 very wide range in distribution, from the temperate climate of 

 Hunter's River, in lat. 33° S., to the torrid and arid shores 

 of Arnheim's Land, in 13° N., and Cooper's Creek in 

 Central Australia, in which latter localities Mueller states 

 that it is the only known orchid. 



The specimen here figured flowered in Messrs. Veitclr's 

 nursery in April, 1870. 



Descr. Stems almost pseudo -bulbous, one to three inches 

 long, clothed with leaf-sheaths. Leaves four to twelve 

 inches long, half to one inch broad, exactly linear, acute, 

 keeled, ribbed when dry. Scape and raceme as long as the 

 leaf, pendulous, laxly many-flowered ; bracts minute or 

 rather large, one tenth to one third of an inch long, scarious 

 when dry, when fresh appressed to the pedicel ; pedicels very 

 slender, together wilh the short ovary one inch long. Flowers 

 coriaceous, two-thirds of an inch diameter ; perianth-segments 

 thickly coriaceous, spreading, inner rather smaller, elliptic- 

 oblong, subacute, concave, brown with green margins, back 

 • greenish-brown, inner deeper coloured. Lip shorter than the 

 petals, recurved, white with pinkish blotches, 3-lobed at 

 the middle, lateral lobes narrow and small ; mid-lobe ovate
