hues of the front is very remarkable, and rendered all the 
more so by the habit of the plant, which (in the specimen 
here figured) turns all the flowers on one side of the raceme 
to the observer and the other away; considering that the 
raceme is erect, this suggests either a possible rotation of 
the rachis so as to expose the flowers by turns to the light, 
or an arrangement by which one side secures the forenoon 
and the other the afternoon exposure to the light. 
Duscr. Pseudobulbs ovoid-oblong, about three inches 
long, compressed, green. eaves seven to ten inches long, 
linear-lanceolate, acuminate, keeled, deep green above, paler 
beneath. Raceme erect, longer than the leaves, 8—10-flowered, 
nearly naked, peduncle and rachis stiff, green; bracts small, 
triangular-lanceolate, shorter than the pedicels. //owers two 
inches in diameter ; perianth spreading, dull yellow-green on 
the back, except at the tip. Sepals elliptic-oblong, acuminate, 
rich maroon brown, with golden tips and bases. Petals 
equalling the sepals, golden yellow, with very broad trans- 
verse maroon brown lobed blotches. Zip oblong in outline, 
shortly clawed, white with rose-coloured blotches; lateral 
lobes rounded, obscurely crenate ; terminal suborbicular, api- 
culate, erose; disk with about ten keels radiating from the 
claw, of which the four inner are produced on to the surface 
of the basal lobe, and end each in a spinous process. Column 
— at the tip, wings incurved, deeply 3—6-toothed.—
