ORCHIS BLEPHARIGLOTTIS. Willd. Fringed white Orchis.

 spur longer than the germ. 



This very delicate species resembles O. ciliaris in its habit, 

 and would be difficult of distinction but for its colour. Spike 

 rather short with snow white flowers. Germs slender, longer 

 than the bractes, twisted, tapering upward. Outer petals round- 

 ish, concave, the upper one erect, the two lateral ones reflexed. 

 The two inner petals much smaller, linear, fringed at the end. 

 Lip of the nectary lanceolate, fringed at the edge. Spur longer 

 than the germ, being nearly an inch in length. In swamps and 

 meadows, rare. Cambridge &c. Perennial.
