Spike many flowered, from 9 inches to a foot long. Flowers closely 
packed, orange coloured, with greenish white reticulated bracts, very sweet 
scented, with the odour of violets, which may be perceived at the distance 
of 40 paces, according to Póppig.

It is not improbable that 6 is a distinct species, but I have only seen an 
imperfect specimen. The original species has flowers with the petals and 
upper sepal white, the lateral sepals tipped with green, the labellum yellow 
with a green edge and spots.

Scape about 2 feet high. Flowers sweet-scented, variegated with white 
green and yellow, with very acute yellowish green bracts. Appendages 
of the lip deep greet; according to Póppig. 
The whole habit of this plant is like the last, of which I should have 
been inclined to consider it a variety if the labellum, very carefully de- 
scribed by Péppig, were not so entirely different.
