Oncidium cucullatum D. nubigenmn. Lindl. FoJ. Orchid. Oncidium, p. 22. 



Of this remarkably pretty Orchid I received two varieties 

 last year, the one in December, with white sepals and petals, 

 from Wentworth Buller, Esq., and the other in June, with 

 these organs of dingy purple, from Messrs. Backhouse and 

 Sons, of York ; both are clearly referable to Lindley's very 

 variable 0. cucullatum, var. nubigenum, though differing in 

 the purple spot at the base of trie lip. The specimen here 

 figured is Mr. Backhouse's, and, though smaller than the 

 wild specimens in our Herbaria, has more flowers. It is a 

 native of forests on the western side of ridge of Asuay, in 

 Ecuador, alt. 11,000 feet, where it was discovered by Professor 

 Jameson, of Quito, some thirty years ago, and is one of the 

 most alpine of the genus, though Dr. Eindley mentions 

 another variety of the same species" ' (cucullatum) as ascending 

 to 13,000 feet. 



Descr. Pseudobulbs an inch and a half to two inches long, 

 narrow-oblong, compressed, smooth. Leaf solitary, five to 

 8even inches long, three-quarters of an inch to an inch broad, 

 linear-oblong, acute, deep green, plane, coriaceous. Scape very 

 slender, erect or inclined, sheaths distant. Baceme simple,
