It was sent by that gentleman in October, 1839, and flow- 
ered in the stove in the same month of the following year. 
Nothing can well be more beautiful than the colouring and 
marking of the upper side of the labellum. 
Descr. Pseudo-bulbs four to five inches long, between 
ovate and oblong, compressed, furrowed, when young, 
clothed with membranous, striated scales, terminated by 
two sword-shaped, coriaceous, faintly-striated eaves, which 
are obtuse at the point. Peduncle or scape from the base 
of a young pseudo-bulb, two feet and more long, bearing a 
copious, spreading peduncle of many handsome, large-sized 
flowers. Sepals and petals uniform, spreading horizontally, 
linear-obieng, spathulate, rather acute, the sides bent back; 
the colour yellow-green with a dull purple blotch below 
the apex. Labellum shorter than the perianth, broadly, and 
in its outline almost orbicular, deeply three-lobed, free from 
any union with the column, except just at the base: the 
two side lobes moderately spreading, yellow veined, the 
veins reddish at the base, where there is a deep carina or 
fold; the middle lobe large, broad, very obtuse, deep 
yellow, singularly waved and crisped at the margin, beau- 
tifully marked with, as it were, beaded stripes, dichotomous 
and terminating within the margin. Column yellow-green, 
speckled with red, above, on each side, having a short, 
obtuse wing. Anther-case deep-yellow, somewhat hemi- 
spherical, but with a deep, broad furrow down the middle. 
Pollen-masses as in the Genus.
