three-lobed, two lateral lobes forming a cordate base to the 
lip, and dotted with reddish-brown, having a three-lobed, 
whitish crest, spotted with red, the middle lobe two-toothed 
at the base ; terminal lobe cordate, its sides involute, its 
margins waved; a broad irregular band of red-brown 
runs along just within the margin. Column short, yellow, 
fringed at the upper margins with glandular soft spines, of 
which the upper one on each side is the longest, lower _ 
down bearing two, yellow, fleshy wings, obscurely fringed 
with glands at the extremity. Anther-case helmet-shaped, 
two-celled. Pollen Masses two-lobed at the back, placed 
at the point of a thin, ovate, membranous, white pedicel, 
whose margins are revolute, and which has a large brown 
gland at the base. Germen small, lineari-clavate, striated. 
From the stove of the Glasgow Botanic Garden, to which 
the plants were liberally communicated by the late Baron 
De Scuacx, from Trinidad. The species blossomed in 
1826, and again in June, 1827. It is among the most sin- 
gular and most beautiful of the extensive parasitic family 
with which our hothouses are now so abundantly stored ; 
and is well named Oncip1um Papilio by Mr. Linn ey.
