callo trifido in basi disci, lacinulis lateralibus obtusangulis, 
lacinula media acuminata, androclinio subintegro. 
It is very curious that our plant was stated, both in England 
and in Belgium, to come from Mexico; yet the wild specimens 
we have at hand come from the Organ Mountains, where the late 
Gardner! found them in dense tufts on large trees (No. 626). 
It is striking that I never found a single specimen among the 
numerous Mexican Orchids I had in my hands. I am, however, 
far from denying the statement of the gardeners; for, if some 
indications have proved quite wrong, many others rejected before 
by botanists proved finally correct. The first plants flowered in 
Europe with Stephen Cannon, Esq., of Stratford Green, and 
Mynheer van der Maelen, in Belgium, the unfortunate gentleman 
who was honoured by the dedication of ugly Maelenia, a monster 
of Epidendrum (Cattleya) Forbesii. Later it appeared in the 
Jardin des Plantes at Paris, where it was well recognized as a 
Vandew by M. Brongniart. Then we had it in Consul Schiller’s 
collection at Hamburgh; in the English collections of W. Wilson 
Saunders, Esq., the Lord Bishop of Winchester, and 8. Rucker, 
Esq.; yet it appears that the greenish yellow flowering plant, 
with its orange anther and callus, never lives long in our 
gardens. 
Rhizome creeping. Pseudobulb fusitorm, with scariose whitish 
afterwards brownish sheath. Developed leaves generally five, 
distichous, linear-ligulate, obliquely rounded, with an apiculus. 
Raceme or panicle nodding. Flowers distant from one another 
in all specimens I ever saw, but represented as very dense by our 
artist. Bracts triangular, very much shorter than the stalked 
ovaries. Sepals oblong, bluntly acute or quite blunt. Tepals 
cuneate ligulate. Lip adnate, with a trifid blade; lateral lacume 
falcate, with involved outer limb; middle lacinia narrow, trian- 
gular, straight; a depressed trifid callus at the base of the hp, 
with obtuse-angled lateral teeth and along acute middle tooth 
going towards the apex of the middle lacinia. Column conical. 
Androclinium lobed. <Anther reniform, quadrilocular. Pollinia 
elobose, adhering in collateral pairs to two linear caudicles. 
Glandule triangular, often emarginate on its anterior sides. 
Materials :—T'wo pages full of analytical sketches made at 
various times from the living flowers; six herbarium specimens.
