ably differing in these respects, from Mr. Cross; to whom 
we owe a very excellent collection of parasitical OrcuipEz, 
which he brought from Trinidad in 1835. All the varieties 
flowered freely in the stove of the Royal Botanic Garden, 
Edinburgh, in April, 1837, and continued for several weeks 
in great perfection. 
Descr. Root of strong, cylindrical, waved fibres. Pseudo- 
bulbs wanting. Leaves (one foot four inches long, three 
inches and a half broad) solitary, lanceolate, very thick and 
rigid, dull green, having small, brown, circular spots on 
both sides, folded along the middle, keeled behind. Scape 
(three feet high), slender, brown, with numerous small, 
greenish-yellow oblong spots, panicled or racemose, with 
small alternate, subacute, membranous sheaths. Flowers 
large, yellow, with large, brown, confluent spots, which 
cover nearly the whole upper surface, but are somewhat less 
continuous behind. Sepals all distinct, unguiculate, undu- 
late, crenulate, warted on the back, the upper rotundato- 
rhomboid, the lower spathulato-oblong and slightly cohering 
near the insertion of their claws only. Petals resembling the 
upper sepal, but larger, and without warts behind. Lip 
three-lobed ; the side-lobes small, blunt, revolute in their 
edges, the central lobe large, kidney-shaped, emarginate,’ 
rather less undulate than the other parts of the perianth, and 
like them crenulate, without warts behind; crest of three 
longitudinal, erect lamella, of which those at the sides are 
interrupted in the middle, that in the centre is nearly 
entire, becoming broader downwards. Column about as 
long as the claw of the upper sepal, colourless, with two 
large kidney-shaped wings, emarginate at the upper edge, 
pink-coloured in front, and two smaller, rounded, entire, 
internal wings. Anther-case white, helmet-shaped, crested, 
emarginate at its anterior edge and sides, minutely pubes- 
cent. Pollen-masses pear-shaped, furrowed behind, placed 
on the upper edge of a white membrane, which has its 
origin from the anterior border of the subrotund gland, 
and covers the upper surface of this. Graham.
