Bohnhoffianum has a dorsal of curious shape. The crest rises sharply between square shoulders which fold over, displaying the reverse. It has no spots, but at the base is a chestnut blotch, changing to vivid green, which again vanishes abruptly, leaving a broad white margin. Vivid green also are the petals, with brown lines; the slipper paler. This example is unique.
Macfarlanei is all yellowish green, with a white crest.
Amesiae.—The dorsal has a broad white outline and a drooping crest. To white succeeds a brilliant green, and to that, in the middle, bright chestnut. Chestnut lines also, and dots, mount upward. The green petals are similarly lined, and the slipper is greenish, tinged with chestnut.
Longisepalum is flesh-colour, with a greenish tinge and pink spots on the very long dorsal. The pink spots change to lines upon the petals. Slipper ruddy green.
Dimmockianum.—The broad and handsome dorsal is green, with white margin. A red stain at the base is continued in lines of spots upwards. The petals are scored with the same colour.
Measuresiae.—Big, with a grand dorsal, pale grass-green below, broadly whitening as it swells. Petals the same green, with a dark midrib and fainter lines. Slipper yellow.
Rona is an example of the common type in its utmost perfection—large, symmetrical, its green tinge the liveliest possible, its white both snowy and broad, and its spots so vigorously imprinted that they rise above the surface like splashes of solid chocolate.
Majesticum is another of the same class, but distinguished by the enormous size of its dorsal.
Dorothy.—Dorsal greenish yellow, with faint spots of chestnut and a broad white margin. Petals and slipper the same greenish-yellow tone.
R. H. Measures.—For size as for colour this variety is astonishing. Its gigantic dorsal is white, prettily stained at base with pale green, in which are enormous red spots, irregularly set. Petals tawny greenish, with lines and dots of red. The slipper matches.
