101 ENGLISH BOTANY. 



lateral lobes; the whole of the perianth segments greenish-white; 

 s])iir tliick, ovate, conical, obtuse, decurved, not half the length of the 

 ovary. 



In pastures in hilly districts. Rather local. With the exception 

 of Sussex it appears to occur in England only in Wales and the 

 northern counties ; but in Scotland it is not uncommon, reaching 

 to Orkney and Shetland. In Ireland it is widely though locally dis- 

 tributed, but most common in the north and west. 



England, Scotland, Ireland. Perennial. Summer, early Autumn. 



Root consisting of tapering fleshy fibres of unequal size. Stem G 

 inches to 1 foot high. Leaves ascendmg or erect, rarely above 1 or 2 

 inches long, the lowest ones broader and blunter than the others. 

 Spike I' to 3 inches long, with the flowei's turned to one side. Ovaries 

 curved so that the flower is horizontal or slightly drooping. Bracts 

 subherbaceous, about as long as the ovary or longer. Perianth seg- 

 ments scarcely ^ inch long, ovate, obtuse, the lip scarcely longer than 

 the other segments, and subconnivent with the others. Anther-cells 

 nearly parallel, and thus making an approach to those of the next 

 genus, in which G. albida is placed by many authors ; but I have 

 included it in Gymnadenia on the authority of the younger Reichen- 

 bach, the greatest living authority on Orchidacese. 



Small White Orchis. 

 French, Orchis lilanc. German, Weissliclie Hoswurz. 



GENUS IV.— E. ABENAKI A. Brown. 



Perianth spreading, or the five upper segments connivcnt ; labellum 

 turned downwards, spurred at the base. Anther wholly adnate to the 

 column, its two cells separate and diverging at the base or subparallel, 

 each containing a pollen-mass, of which the caudicule is aflSxed to a 

 gland ; the two glands not included in a pouch. Stigma without 

 a rosteUate process extending between the bases of the anther- 

 cells. 



Herbs with tapering rootknobs. Habit similar to that of Orchis. 



The derivation of the name of this genus is given by Dr. Mayne and others as 

 from the Latin Imhena, a rein or thong, which the elongate labellam of the conunonest 

 species is supposed to resemble.
