O. incurvum, Barker in Bot. Reg. 1840. mise. 174. 
This striking, and very peculiar species, was first observed 
in this country, by George Barker, Esq. of Birmingham, 
from whose rich collection we were favoured with flowers in 
1840. Since that period it has found its way into the pos- 
session of others, especially of Mr. Ferguson, late gardener to 
the Duke of Buckingham, who succeeded in growing It ex- 
tremely well. It is, however, still one of the more rare 
species. 
Mr. Barker gave it the name of incurvum, in consequence 
of the petals having a great tendency to turn inwards when 
the flowers first open; that tendency is, however, eventually 
lost, and the parts assume the position customary in the 
genus. 
In some respects it resembles the Birds-bill Oncid, but it 
bears its flowers in a long, erect, and even branched panicle, 
and it has neither the long rostel, nor the great column-wings
