This most curious plant was introduced some years ago 
from Guatemala by Geo. Ure Skinner, Esq. and was after- 
wards found in the same country by Mr. Hartweg. When I 
first published it I knew it only from report, and a single 
damaged dried flower, and consequently several inaccuracies 
crept into its description, which led to its being misplaced in 
the enumeration of the genus published in the Sertum Orchi- 
daceum. Its real situation is near O. deltoideum. 
Although not a very splendid plant, it is far from being 
undeserving notice. Its very glaucous flower-stem, the snow- 
white lip and crimson petals, lying as it were in the middle 
of dusky brown sepals, produce a singular and pleasing effect. 
For the opportunity of figuring it, we are indebted to J. C. 
Harter, Esq. of Broughton, near Manchester, who was so 
obliging as to forward specimens, along with a drawing by 
Mrs. Powell, in September last. Mr. William Ashton, the 
gardener to Mr. Harter, also deserves to be mentioned, as 
having succeeded in flowering the plant before any one else.
