_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.
_Harefield Hall_ variety resembles this, but smaller. The great spots of the dorsal are more crimson, the petals and slipper a darker hue.
_Frederico._--Within a broad white outline the dorsal is all yellow, heavily spotted and splashed with chestnut. The reddish tawny petals are lined and spotted with chestnut, and the tawny slipper shows a chestnut network.
_Corrugatum._--The name refers to a peculiarity unique and inexplicable. The slipper, so smooth in every other case, has a strong breastbone, so to say, and five projecting ribs on either side, arching round diagonally from the back--pale brown on a darker ground. The dorsal is all yellow, spotted with brown, but the crest overhangs, showing its white underside.
_Drewett's variety._--Dorsal white, with a green base and huge blotches of red-brown; greenish petals lined with the same; ruddy greenish slipper.
_Eximium._--A natural hybrid doubtless, though we cannot guess what its other parent may be; it came among a lot of the ordinary form. Very small. The funny little dorsal is yellow, spotted throughout with red. The small petals have a crimson tinge, much darker in the upper length. Slipper dull crimson; the yellow shield of the column is very conspicuous on that ground.
_Hector._--The dorsal is pale grass-green, with a white crest and margin and large chestnut spots; petals and slipper reddish ochre.
