The first account which appeared of this singular plant 
was in the sixth volume of the Transactions of the Horti- 
cultural Society, in a Report upon the New or Rare 
Plants which had flowered in their Garden at Chiswick, 
from its first formation to March 1824. To this establish- 
ment the plant was introduced from Bahia de St. Salvador, 
in 1823, by Mr. George Don. Our drawing was made in 
the Society’s garden, in August 1824. 
The present plant differs from all the other species of 
Catasetum in the form and nature of its labellum, and in 
the manner in which the sepals are expanded. But in 
every other respect, in its habit, foliage, inflorescence, and_ 
especially in the structure of its columna, it entirely agrees 
with Catasetum. 
The unimportance of the peculiarity which exists in the 
labellum is manifested in a singular manner by a curious 
monster of this plant which we observed on an individual 
in the Horticultural Society’s Garden. Among flowers of 
the ordinary structure, two or three others were observed in
