104 ENGLISH BOTANY. 
lateral lobes; the whole of the perianth segments greenish-white; 
spur thick, 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 6 
inches to 1 foot high. Leaves ascending or erect, rarely above 1 or 2 
inches long, the lowest ones broader and blunter than the others. 
Spike $ to 3 inches long, with the flowers 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 Orchidacee. 
Small White Orchis. 
French, Orchis blanc. German, Weissliche Hiswurz. 
GENUS IV-HABENARIA. Brown. 
Perianth spreading, or the five upper segments connivent; 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 affixed to a 
gland; the two glands not included in a pouch. Stigma without 
a rostellate 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 habena, a rein or thong, which the elongate labellum of the commonest 
species is supposed to resemble.
