Discovered by Swaiason in the neighbourhood of Rio de 

 Janeiro, and sent by him to the Botanic Garden at Glasgow, at that 

 time directed by Dr., afterwards Sir W. J. Hooker, where it 

 flowered for the first time in 1819. It was afterwards cultivated by 

 Mr, Cattley at Barnet, by Sir Charles Lemon at Carclew under the 

 name of Oncidium ciliatum, by our predecessor at the Royal Exotic 

 Nursery, Mr. Knight, and by Messrs. Loddiges of Hackney. It is 

 now less frequently seen than formerly, being surpassed as a horti- 

 cultural plant by other Oncids with more showy flowers. The species 

 is a variable one, especially in the form and size of the front lobe 

 of the lip, and in the colour of the sepals and petals, whence several 

 varieties have been noted and distinguished by name. The specific 

 name refers to the fringed or bearded disk on which the crest is 

 seated.

 acute, reflexed ; the petals broadly ovate, reflexed and twisted ; lip
