DESCRIPTION. 
Pssvponvuss 8 or 4inches long by nearly as many wide, much flattened, and very sharp at the edges, always powdered with 
> 
minute brown dots, which do not appear until the second year. Leaves oblong, broad, and stiff, acuminate at their 
extremities, much shorter than the scape. Scarn generally simple, but sometimes slightly panicled, about a yard 
high, and bearing from 10 to 20 agreeably scented Frowers. Bracrs of a delicate texture, boat-shaped, scarcely 
more than one-third the length of the ovary. SEPALS and 上 PTALS nearly equal, broadly ovate, about an inch long, 
of a green colour, covered with rich reddish-brown spots. Lip broad and spreading, heart-shaped, acuminate, and 
turned inwards at the apex, its disk white, but covered with round blue spots, which cease at the foot of the isthmus 
(claw), where two upright and nearly parallel lamelle (plates) are stationed. COLUMN furnished with ovate, decurved, 
round-headed wings. 
This is a robust and stately plant, nearly allied to O. Bictoniense to which at one time Dr. Lindley was disposed to 
refer it, but far larger and handsomer in all its parts. Its broad pseudobulbs which become covered in their second 
year with a multitude of small reddish dots, its wide sepals and petals, the spotting of its lip, and its general resemblance 
to Zygopetalum Mackaii will, however, sufficiently distinguish it. Being found at a higher elevation than O. Bictoniense, 
it requires to be kept more cool, and as it affects dark and wet banks in its native wilds, it is better to place it in a north 
house where it can be more readily protected from the sun. "Treated in this way it grows luxuriantly and flowers 
abundantly at Knypersley, whence the specimen figured in the Plate was derived. Its flowermg season seems to vary, for 
while with me it is now (May) coming into bloom, about London November is the more usual month. 
O. Uro-Skinneré was the latest discovery of my indefatigable friend Mr. Skinner (after whom it was named by 
Dr. Lindley), and who, though now settled in England, is as much devoted to his favourite tribe as when, while resident 
in Guatemala, he was wont to delight the Orchidists of Europe by the multitude of new and beautiful plants that he was 
constantly dispatching across the main.
