The flowers of this plant are as large as those of A2. macrosta- 

 chya, one inch across, to which species it is most nearly allied. 

 They are white with a yellow centre, according to Deans Cowan. 

 The stem and leaves much recall those of Cryptopus elatus, the 

 latter being lanceolate and shorter, and more distant than in most 

 of the other species of the genus. The peduncle is very long in 

 proportion to the stem, in Deans Cowan's sketch nearly 2 feet 

 long, while the stem is only 6 inches. The lower part bears a 

 few distant dark-brown sheaths. The flowers are few. The petals 

 are | an inch long, 5 lines across in the broadest part. The lip is 

 1 inch long and £ inch in diameter. Neither in Thouars's type- 

 specimen in the British Museum nor in Deans Cowan's drawing 

 do I see the cusp between the lobes of the lip figured by Thouars. 

 The leaves are figured and described by him also as acute, but, 

 according to Deans Cowan, they are slightly unequally bilobed 

 at the apex.
