bia river. In 1811, Mr Nuttall gathered it, but without 
flower, on the Island of St Helena, near the outlet of Lake 
Michigan, in the shade of Abies canadensis, attached to re- 
cent vegetable soil. 
Mr Brown has separated, in the Hortus Kewensis^ the 
American state of this plant from the European, and has 
ascribed to it, " a lip narrowed and subunguiculate at the base, 
the spur exceeding the lamina or ligule of the lip in length, 
and the peduncle longer than the germen." The first charac- 
ter is by no means apparent in my living specimens. The se- 
cond is variable ; for though, in the individuals here figured, 
the spur is longer than the ligule, yet, in some of those in my 
herbarium, which were gathered by Mr Goldie at Montreal, 
the ligule rather exceeds the spur in length, and the peduncle 
is about as long as the germen. I have, for these reasons, ven- 
tured again to unite the American species with the European, 
particularly as it sufficiently well accords with the figure of the 
latter given by Swartz in the Svensk Botanik. The ligule, 
I should however observe, in Swartz's plate, is represented 
much larger in proportion than in my specimens, and entire at 
the extremity. 
Smith says, that he has in vain sought for a permanent 
difference between the American and European plants ; and 
Richard adds, " An Calypso Americana, Hort. Kew. 208. 
specie differat non satis constat." 
The Genus was established by Salisbury, in his beauti- 
tiful Paradisus Londinensis, " from tcaXv^o, to cover, or 
conceal, not merely alluding to the covering of the stigma, 
but preserving a poetical analogy between this botanical beauty, 
so difficult of access, and the secluded goddess, whose isle was 
fabled to be miraculously protected from the observation of na- 
vigators." — Sm. in Bees' Cycl. 
In Europe, the plant is considered of great rarity. In 
Canada, especially about Montreal, it appears to be not un- 
common. 
Its mode of cultivation with us is in pots of peat-earth ; 
and it is sheltered by a frame in winter.
