Wilckeanum.—Upon internal evidence Reichenbach pronounced this a natural hybrid of Od. crispum × Od. luteo-purpureum. It was one among innumerable instances of his sagacity. A few years ago M. Leroy, gardener of Baron Edmond de Rothschild at Armainvilliers, crossed those two species and the flower appeared in 1890. It was Od. Wilckeanum; but for the sake of convenience this garden hybrid is called Leroyanum.
Wilckeanum pallens.—A form still rarer of this rare variety; yellow-ivory in colour, heavily splashed with brown; lip white, with a brown bar across the centre.
Wilckeanum albens.—Very large, white instead of yellowish; spotted and blotched with brown.
Ruckerianum.—Sepals and petals white in the centre, edged with violet, yellow lip; all spotted with reddish-brown.
Ruckerianum splendens.—Larger and more finely coloured in all respects than the normal form. The violet margin is broader.
Vuylstekeanum.—Those who saw the original plant of this noble species at the Temple Show some years since have not forgotten the spectacle assuredly. Petals and dorsal sepal pale yellow; lip and side sepals brightest deepest orange.
Mulus.—A natural hybrid of Od. luteo-purpureum with Od. gloriosum no doubt. It bears a strong spike, branched, with many large flowers, bright yellow blotched with pale brown. But the colouring varies greatly.
Josephinae.—Named after Miss Josephine Measures. White, with a rosy flush; sepals and petals spotted with chocolate at the base.
Hunnewellianum.—Small, but very pretty. Sepals and petals pale yellow, profusely dotted with brown; lip white, with a single brown spot.
Elegans.—Assumed to be a natural hybrid of Od. cirrhosum and Od. Hallii. The ground colour, faintly yellow, is almost concealed by chocolate spots and patches; lip white, with a large blotch in the centre.
