This is another extremely handsome Mexican Orchideous © 
plant, for which the Woburn Collection is indebted to 
JOHN Parkinson, Esq. It is remarkable for its large, thick, _ 
and very coriaceous leaf, its ample panicle loaded with — 
blossoms of a greenish yellow colour, spotted with orange _ 
and red purple, and not destitute of fragrance. It flowered — 
in January.
