A very elegant species^ first cultivated by the Rev. John Clowes, 

 of Brougliton Hall, near Manchester, and by Messrs. Loddiges, of 

 Hackney, about the year 1840, neither of whom left any record of 

 its origin, which remained unknown to science till its habitat was 

 revealed by M. Pine], a French merchant trading in Brazil, who 

 collected it in the neighbourhood of Novo Friburgo and sent 

 plants to various correspondents in France and Belgium, including 

 M. Van Volxem of Brussels, one of whose plants was figured in 

 Linden's Pescatorea, published in 1860. 



Oncidium phymatochUum is a remarkably distinct species both as 

 regards its flowers and its vegetative organs, and one not likely to 

 be confused with any other ; it has been inaptly compared with 

 Odontoglossum ncevium. The specific name refers to the crest of the 

 labellum, from 'pvf.ia^ "a, tumour," and )(e iXoc, "a lip."

Santa,* and afterwards in the province of S^o Paulo, in southern 



Brazil, by Mr. E. D. Jones who sent it to Mr. J. H. Wilson, of 



Liverpool, in 1873; it was shortly afterwards imported by ourselves 



from Rio de Janeiro.
