crispa of Dr. Linney above quoted, the chief difference 
consisting in the reddish colour and more acute lobe of the 
lip in the flowers of our plant. Shortly after, in Part III. 
of Dr. Linptey’s “ Sertum Orchidaceum,” appeared, from 
a drawing made in Surinam, a second species of the Genus 
S. marginata, having flowers, which in their hue and middle 
lobe of the lip nearly resemble the present: but the margin 
of the petals and sepals is of a yellow colour, and the lip is 
less waved. ‘To this, however, I find in Prof. LinpiEy’s 
Miscellaneous notices (Bot. Reg., Feb. 1839,) that Mr. 
Brockxenvrst’s plant is unquestionably referred ; an opin- 
ion in which I readily acquiesced : but seeing how liable 
the colour of the inflorescence is to vary, it may admit of 
doubt how far the only two species yet described are really 
distinct. 
Descr. The specimen from which our figure was taken 
has twenty pseudo-bulbs, similar to those here represented, 
oblong, furrowed, stipitate and sheathed with pale brown 
scales, each bearing, at the summit, two or three large ob- 
long lanceolate, coriaceous leaves. From the base of the 
upper leaf arises the flower-stalk, a foot, or a foot and a half 
high, rounded, bracteated, bearing a broad raceme, or, rather, 
corymb of flowers, each blossom subtended by a reflexed, 
linear-lanceolate, membranaceous bractea. Sepals oblong, 
spreading, remarkably crisped or undulated, of a dull brick- 
red colour. Lip nearly white, tinged with pink, and yellow 
at the base, oblong-ovate, waved, but less so than. the 
petals, three-lobed, the disk elevated and marked with 
about five raised, waved lamelle, the side-lobes short, ob- 
tuse, the terminal one cordate, rather acute. Column semi- 
cylindrical, parallel with the lip. Anther hemispherical, 
yellow.
