native of Brazil, whence the pseudo-bulbs were originally 
imported by the Earl of Arran, who has been indefatigable 
in introducing rare plants to the gardens of this country: 
and to whom we had dedicated the species just before its 
appearance in Dr. Linptey’s splendid work on Orcuipace& 
above quoted. There can be no doubt, I think, of the two 
plants being the same, though the colour of the lip from 
which the specific appellation is derived is at variance with 
its name :—here being yellowish with a tinge of purple. 
The column, on the other hand, in our plant, is white, or » 
pale yellowish-white, in Linpiey’s plant purple. Both states 
are very beautiful, and highly worthy of a place in every 
— collection of Orcuipem. It flowered in October, 
Descr. Pseudo-bulbs oblong, broader at the base, even 
on the surface, partially sheathed below by two leaves, and 
bearing two leaves at the apex. ‘These leaves are linear- 
oblong or ligulate, nerveless, shorter than the scape, which 
arises from the axil of the leaves at the base of the bulb, and 
is a foot and a half to two feet high, bearing a raceme of 
large, handsome flowers, each subtended by an ovato-lance- 
olate, appressed, squamiform bractea. Sepals and petals 
nearly uniform, spreading horizontally, oblong, rather acute, 
waved, bright yellow, with large, ferruginous blotches. 
Lip standing forward, broadly-obovate, subrotundate, ob- 
scurely lobed, waved and crisped, the base convolute about 
the column, bearing five small lamellz, the rest spreading ; 
the colour yellowish, with a faint blotch of purple. Column 
short. Margin of the stigma reddish; this issurrounded by 
the membranous apex of the column (or clinandrium) which 
is crisped, with two teeth or little ears at the base, and den- 
ticulate at the extremity. Anther-case hemispherical, yel- 
low. Pollen-masses two, with a caudiculus, and an oblong, 
brown gland. :
