native of Brazil: first detected there by Mr. Doveras, and 
since found in the Organ mountains by Mr. GarpNner, whose 
flowering plant, grown in the Glasgow Botanic Garden, 
is here represented. It blossomed first in October, 1839. 
Descr. Pseudo-bulbs clustered, nearly cylindrical, fur- 
rowed, but not deeply, bearing at the extremity a solitary 
leaf, which is lanceolate, obscurely nerved, somewhat cori- 
aceous, acute, almost acuminate. Scape slender, rising from 
the base of a pseudo-bulb, and, including the panicle, a foot 
ormore long. Sepals and petals pale yellow-green, banded 
with orange, oblongo-spathulate, concave: the two inferior 
sepals combined into one, shorter than the upper and emar- 
ginate. Lip panduciform, bright yellow, near the base 
blotched with orange-red: the side-lobes are very narrow, 
almost linear, channelled beneath: the middle one nearl 
orbicular, of an uniform yellow colour, (not bordered with 
red, as in the plant figured in the Botanical Register). 
Near the base, the disk is crested with orange-red tuber- 
cles, and furnished with two projecting horns. Column 
pale yellow, downy above, and with a projecting, linear, 
obtuse wing on each side. Anther-case hemispherical, with 
two recurved horns at the lower margin, downy. Pollen- 
— two, with a long, slender caudicula and a minute 
gland.
