many years since by Linden from New Granada, but still ex- 
tremely rare. The figure was taken from specimens produced 
in the spring of 1865, in Mr. Rucker’s far-famed collection. 
Being found at a lower elevation (4000 ft.) than the majority 
of its tribe in New Granada, it requires rather more warmth 
than most of what are now denominated “ cool” Orchids. 
Descr. Pseudobulbs ovate, deeply furrowed, shining, two 
or three inches long, bearing two large, broadly-lanceolate, 
very sharp-pointed, leathery leaves. Flower-scapes much shorter 
than the leaves, three- to five-flowered. Sepals free, lanceo- 
late, very sharp-pointed, fully expanded, all of the same size, 
olive striped with reddish-brown. Petals rather smaller, 
slightly fleshy, broad at the base. Lip with a short claw, 
jointed with the extended base of column, rather hollow, 
three-lobed, its middle lobe largest, fringed, and very acumi- 
nate, white with purple streaks, and orange-coloured calli at 
the base. Column arched, with membranous edges, and trun- 
cate, toothleted wings. Anther two-celled. Stigma hollow, 
with sharp beak and oval gland narrowing to a point in front. 
Pollen-masses four.—J. B.
