This graceful orchideous plant is a native of North Ame- 
rica, extending from Canada * to Carolina, according to Pours; 
and it appears from the account given of it in the Botanical 
Register (where a dwarf state of the plant is represented), to 
have been introduced into our gardens about the year 1815 by 
Mr Nutraut. The specimens here figured flowered in great 
perfection, along with the still rarer Habenaria blephariglot- 
tis, in the garden of Dalhousie Castle, under the superintend- 
ance of Mr Arcuisaxp, ffom roots sent from Canada by 
Lady DaLHousi£. 
This genus, as characterised by Mr Brown, comprises only 
a part of the species included in Jussrev’s Pogonia, and is 
distinguished from Arethusa, 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.
