ONCIDIUM. 



55 



originally introduced from Rio de Janeiro about the year 1850^ and 

 that it has since been gathered near Novo Friburgo, on the Organ 

 Mountains. It has been generally cultivated since that date, its 

 small size and free-flowering habit having secured for it the favour 

 of many amateurs. As a horticultural plant the variety Croesus is 

 superior to the type, the strong contrast between the golden yellow 

 of the labellum and the brown-purple of the other segments being very 

 striking; it was introduced about the same time as the species, but it 

 has always been very rare. 



Oncidium longipes. 



Very near Oncidium longipes, and probably only a variety of it is 

 On. uniflorum, figured in the Botanical Register of 1843, t. 43, 

 which, according to Dr. Lindley, differs from. On. longipes in its one- 

 flowered peduncles and " in the crest of the labellum consisting of an 

 oblong cluster of numerous small smooth fingers, and in the wings of 

 the column being conspicuously two-lobed." * The figure, however, shows 

 no such striking difference except in the column wings. It was 

 introduced from the Organ Mountains by Sir Charles Lemon, in whose 

 collection at Carclew, in Cornwall, it flowered in November, 1842. 

 We find no record of its being in cultivation since that date.
