Cypripedium bulbosum. Linn. Sp. PI. p. 1347. 
Root a small bulb, sheathed with scales, and throwing out from its base 2 or 
3 rather long, and somewhat downy fibres. Stem from 4 to 6 inches, or 
even more, in height, covered, throughout its whole length, with long, 
cylindrical, membranaceous, brownish-green, sheathing scales, and with 
one, rather large, ovato-rotund dark-green leaf, deeply marked with lon- 
gitudinal nerves, and somewhat reticulated. 
Flower solitary, terminal, drooping, about an inch long. Peduncle short, 
curved, as well as the elongated germen. Five segments of the perianth 
lanceolate, rose-coloured, patent, and all curved forward. Lip inclined 
downwards, ovate, remarkably inflated, dingy pink, marked internally 
with deep purple interrupted lines, externally with obscure ones, open 
above at the base, the margins reflexed, with a tuft of yellow hairs at the 
sinus, and running down towards the apex into a broad, pale rose-colour- 
ed, spotless 2-lobed ligule; beneath this, the lip terminates in a sharp, 
bifid, yellow point, which is sometimes longer than the ligule, and some- 
times scarcely equalling it in length. Column of Jructification dilated at 
the margin, into a petal-like form, ovate, convex, rose-coloured, and co- 
vering the aperture of the lip. Anther seated on a small swelling, just 
beneath the extremity of the column on the under side, nearly hemi- 
spherical, yellow- white, membranaceous, moveable, attached by its base ; 
when fallen away leaving 2 pairs of flattened, yellow, waxy pollen- 
masses, attached by their narrower extremities. Stigma a concave heart- 
shaped excavation, in part covered by the anther-bearing process. 
Bulbs of tliis truly beautiful and interesting plant were 
communicated by Mr Kippin, from Montreal to our Botanic 
Garden in 1821, and from those which blossomed there in the 
month of March 1822, the accompanying figures were taken. 
It is a native of Siberia, near the river Lena, in the 55th 
degree of North Latitude, according to Gmelin ; of Ostro- 
bothnia, according to Linn^us. Mr Menzies found it in 
Nova Scotia, as did Governor Lewis on the banks of Colum-
