Professor H. Reichenbach in referring the splendid plant 
here figured to its comparatively pigmy and pale-flowered 
predecessor, described by Dr. Lindley. It should further be 
stated that Mr. Lawrence’s plant is said to be a native of 
Brazil, whilst Mr. Wentworth Buller’s comes from Costa 
Rica; but in the early days of Orchidology, localities and 
habitats were not much attended to. 
_ Descr. Pseudobulbs three inches and a half long, oblong 
in outline, much compressed, with very acute thin edges, 
quite smooth, even, and bright green. Leaves six to eight 
inches long, oblong-lanceolate, coriaceous, very dark green. 
Bracts at the base of the pseudobulb, often leafy. Spikes 
from the base of the peduncle, two feet long, nearly hori- 
zontal, drooping at the apex, many-flowered; bracteoles 
short and small. Ovary one inch long, narrowed into a 
stout pedicel. Sepals very long and slender, a quarter of an 
inch broad at the base, lateral upwards of seven inches long, 
dark orange-yellow, with a few large, deep red-purple 
blotches towards the base. Petals erect, similar to the sepals, 
and as broad, but much shorter, two to three inches long. 
Lip three inches long, ovate-lanceolate, acuminate, pale yel- 
low, with a ring of purple spots at the base, surrounding two 
raised parallel ridges that are slightly pubescent and termi- 
nate in tubercles. Edges of column pubescent.—J. D. H.
