two lateral ones are falcate and smooth, wliile the middle 

 one is rounded, has a strong tooth on each side, and is 

 hordered hy a deep white fringe of necklace-shaped liairs ; 

 then the short stalk of the lip has four or more such hairs 

 growing straight from its border, and the disk is furnished 

 with a large white two-lobed flat tooth, the divisions of which 

 diverge from each other. 



The striping, banding, and painting of the delicate white 

 flowers with rich crimson, produces a very rich and striking 

 effect.
