this has the whole flower of nearly the same uniform pale 
green ;—and 3, A noble raceme sent to us by C. Par- 
KER, Esq. of Liverpool, imported from Demerara also : this 
approaches nearer in colour to Dr. Linpxey’s plant, but the 
colour is much more inclining to yellow or buff, and the 
margin of the lip is less distinct and less fimbriated. All 
are eminently singular and deserving of cultivation. Our 
8. and y. flowered in August, 1836. The following de- 
scription applies to the second of these varieties. 
Descr. Pseudo-bulb five or six inches long in the old 
state when destitute of leaves. In the flowering state of 
the plant it is scarcely more than two to three inches long, 
sheathed by the broad bases of the leaves, of which the 
outer ones are short, the rest a foot or more in length, lance- 
olate, striated, plicate, dark green above, paler and some- 
what glaucous beneath. Scape a foot and a half long, 
arising from the base of the young pseudo-bulb, pale 
green, bearing a lax raceme of seven to nine flowers, of 
a yellowish-green colour, nearly destitute of fragrance. 
Sepals lanceolate, closely reflexed. Petals straight, having 
the direction of the column, oblong, their margins revo- 
lute. Inp large, fleshy, ventricose, yellow and downy 
within, the sides much reflexed and beautifully fringed, 
somewhat three-lobed at the apex, the middle lobe not 
longer than the side ones, very obscurely toothed. Co- 
lumn short, standing forward, quite exposed, the sides 
above thickened and produced, thus forming on each side 
a sort of tooth, directed downwards (corresponding with 
the sete in Caraserum) under the singularly projecting 
margin at the base of the stigma. Anther hemispherical. 
Pollen-masses two, as in Caraserum, furrowed at the back, 
fixed to a large, broad, and highly elastic membrane, 
which, on separating from the column, has its sides singu- 
larly reflexed; this membrane, indeed, often springs UP 
from the column before the falling of the lid, and soon 
turns black, giving the appearance of a black beak to the 
base of the anther, as seen in the lower flower of our 
figure.
