For this curious species we are obliged to the Countess 

 Amherst, in whose collection at Montreal it flowered for the 

 first time in September last. It had been sent home by Mr. 

 Hayne, a Commissioner in Brazil, from the interior of that 

 country in 1829. To the pencil of Lady Sarah Amherst we 

 are indebted for a sketch of the manner in which the plant 

 grows. 



* The genus is named in compliment to the Right Honourable Lord Grey 

 of Groby, a munificent patron of Horticulture, and a most zealous cultivator 

 of Orchideous Epiphytes ; the species records the sense we entertain of the 

 claims of the noble family of Amherst upon the gratitude of Botanists, for the 

 countenance afforded by them to natural history so Jong as their power continued 

 in tlie Eastern world.
