This kind of Spiranthes has been long known in our 
gardens, although it is, like other North American Orchi- 
deze, impatient of cultivation. The specimen from which 
our drawing was taken was communicated by Robert Bar- 
clay, Esq. from his fine collection at Bury Hill, near Dork- 
ing. 
As it has been repeatedly decided, that the generic ap- 
pellation Neottia belongs to the Ophrys Nidus Avis of older 
writers, there can be no reason why the name Spiranthes, 
applied by Richard to this set of plants, should not be re- 
tained; the Gyrostachys of Persoon never having, as far as 
we know, been employed by any author. Spiranthes can 
only be confounded with the Stenorhynchus of Richard, 
which, although not distinguished from it by any very deci- 
sive character, has a peculiarity of habit which renders it 
desirable that it should, if possible, be retained distinct. 
Pelexia of Poiteau, which we formerly (fol. 760), without 
being aware of that name having been published, called 
Collea, is more distinct in character, but less in habit.
