The remarkable Brazilian Orchid which forms the 
subject of our plate was described and figured by Mr. 
Barbosa Rodriguez in 1877 from specimens growing on 
trees at Caldas, in the province of Minas Geraes. It had, 
however, been previously met with by Dr. G. Gardner, 
for there is a specimen of the same plant in the Lindley 
Herbarium which Gardner has noted as being a species 
of Mazillaria, collected by him in March, 1837, on the. 
stems of trees in the Organ Mountains. To this speci- 
-men Dr. Lindley added the note, ‘‘ genus uncertain, 
the only flower was broken and injured by insects.” 
Rodriguez when he described the plant, which he 
dedicated to H.I.H. Donna Isabel, Comtessa d’Eu, 
remarked that it is a very bizarre Orchid with almost 
the habit of a Mazillaria, but with a pollinary structure
