Roots of this plant were received at the Botanic Garden of 
Glasgow from Mr Kippin of Montreal, in the neighbourhood 
of which place it appears to be not uncommon, although it is 
also met with as far southward as New York and Carolina ; 
there, however, affecting shady and rocky situations upon the 
mountains. With us, it flowered during the month of May, 
being placed in a large box along with Primula pusilla, and 
kept in a common frame, wherein air was freely admitted. 
In the color of the flowers, this Orchis varies from purplish 
to a pure white ; and the size of the whole plant, as I perceive 
from specimens given me by Mr Boott, which were gathered 
in the neighbourhood of Boston, frequently exceeds double the 
dimensions of the individual here delineated.
