SUb-Var. — aJhum, flowers wholly white with the exception of the yellow 

 crest of the labellum. 



Originally introduced from Mexico by Mr. George Barker, of 

 Birmingham, in whose collection at Springfield it flowered for the 

 first time in this country in 18 10. It was collected by Ross in 

 the province of Oaxaca, and subsequently by Galeotti at Talea in 

 the same province, at an elevation of 4,000 — 5,000 feet. The 

 specific name was given by Mr. Barker in reference to the

 with that of Oncidinm ornithorhynchum.
