Under the name of Oncidium Cebolleta many very diffe- 

 rent species exist in our gardens, among which the finest is 

 that now figured, which, although it has the foliage of that 

 species, is really very different, forming dense panicles, three 

 feet long, of very large and showy yellow and brown flowers. 

 Its leaves are often three feet long, and hang down or spread 

 upon the ground instead of standing stiff and erect. It has 

 been imported abundantly by the Horticultural Society from 

 Mexico, and has flowered both in their garden and with 

 Messrs. Loddiges. It is very handsome, and well worth 

 growing. 



From all the allied species it differs in the great length of 

 its whip-like leaves, and in the form of its labellum, whose 

 lateral lobes are something like bird's wings in shape, while 

 the intermediate lobe has an unusually long unguis gradually 

 dilating into a two-lobed extremity. 



In cultivation it requires a warm damp atmosphere, where 

 such plants as Cattleyas, Lselias, and Stanhopeas flourish. 

 A temperature ranging from 55° to 65° with artificial heat,
