This graceful orchideous plant is a native of North Ame- 
rica, extending from Canada * to Carolina, according to Pursh; 
and it appears from the account given of it in the Botanical 
Register (where a dwarf state of the plant is represented), to 
have heen introduced into our gardens about the year 1815 by 
Mr NuTTALL. The specimens here figured flowered in great 
perfection, along with the still rarer Habenaria hlepharigloU 
tis, in the garden of Dalhousie Castle, under the superintend- 
ance of Mr Archibald, from roots sent from Canada by 
Lady Dalhousie. 
This genus, as characterised by Mr Brown, comprises only 
a part of the species included in Jussieu's Pogonia, and is 
distinguished from Aretliusa, by the sessile labellum not con- 
nected with the column, by the petals being distinct to the base, 
and by the simply farinaceous, not angular pollen.
