about a foot or rather more high, with narrow, acute, spreading, 

 light-green leaves, 2£ inches in length by | an inch across. The

 white. The ovary and pedicel are white, 1| inch in length, 

 twice as long as the peduncle. The petals and sepals are about 

 | inch long, the petals narrower than the sepals, and spreading, 

 the lateral sepals deflexed. The lip is broader, with a slender 

 spur 3 inches long, white, becoming yellowish towards the apex. 

 The column is rather short. The caudicles somewhat long. The
