Mr. Garpner’s good fortune to discover a fourth species, 
the one here figured, habiting the Organ Mountains, and 
which has been by him sent to the Contributors towards the 
cost of his expedition, both in a living and dried state. It 
seems to grow very freely; for the roots only arrived in 
July, and in the latter end of December the flowers and 
bright green foliage, sheathed at the base with purple mem- 
branes, were in perfection in the stove of the Glasgow 
Botanic Garden. It certainly is a very interesting plant, 
though perhaps less showy than the Mexican ones figured 
by Professor Linptey. 
Descr. Terrestrial. The leaves, solitary or two to- 
gether, springing from the top of the root on long, broad 
petioles, are of an elliptical-lanceolate figure, acute, mem- 
branous, striated and plaited, slightly waved ; the petioles, 
for their whole length, clothed with large, cylindraceous, 
purple membranes as thick as one’s finger. From the same 
sheath the peduncle or scape arises, nearly a foot in height, 
(about as tall as the leaves), purple, sheathed with purple 
bracteas, and terminating in a raceme of large, nearly white, 
almost globose, or rather hemispherical flowers, convex 
above, plane below. Sepals and petals oblong or broadly 
lanceolate, the latter and upper sepal counivent, concave, 
and forming a helmet over the column and lip, while the 
_ two lower sepals almost united at the base under the lip are 
patent and slightly falcate; lip articulated by a very short 
claw, closely applied to the column, broadly oblong, the 
upper half bent back, with a recurved mucro at the point: 
on the disk are two oblong tubercles, and on the margin 
towards the point, three distinct glands, Column semi- 
terete, the base extended, slightly glandular, winged, the 
wings standing forward, very broad upwards. Anther-case 
hemispherical, with a large mucro. Pollen-masses four, in 
two pairs, connected by a gland. Germen clavate, with 
a membranous bractea at the base of each.
