— Flowered with Mr. Knight of the King's Road. Lateral sepals and base of the lip 

 are so uniied in a spur , that their separate nature is entirely concealed lowards ihe 

 point of ihe spur. The rosteliura is a deep two-Iobed lip curved down over ihe stig- 

 matic surface. The pollenmasses are in two pairs , and doep purple and which is 

 exlremely curious , ihey lie upon a loose hard transverse gland , ^M^ich seems to re- 

 place the gland and caudicula of Vandeae , and which projects beyond the anterior 

 edge of the anther resting upon the twolobed rostelhim. The anlher-bed itself is 

 deeply excavateti, and 3-lohed, the anther adhering to ihe back lobe , which is the 

 narrowest.
