 obtuse, anther broadly ovate truncate, its cells convero-ino*

 Platanthera Lindl, Orchis bifolia E- B, t, 22. 



Dry pastures and heaths, sometimes in moist places, frequent, u 

 6 — 8. — A monstrosity sometimes is found at Norris Castle, Isle of 

 Wiglit, in which the spur is absent. Although we have admitted 

 this as a species, we are not convinced that it is essentially distinct 

 from the preceding. The two agree precisely in general appearance 

 and in every character save one, which in that case would reouire to 

 indicate a different structure before it be held sufficient ; the difference 

 consisting merely in the anther of H. chlorantha being more dilated at 

 the base, which may possibly be the effect of luxuriance. We 

 mit it, however, because H. hifolia is itself in the same way inter« 

 mediate between H, chlorantha and the genus Gymnadenia,
