Please excuse that I did not notice the mistake
Phrag. Macorchilum is correct.
The first time when this hybrid flowered, it was described in
‚The Gardeners' Chronicle’ 19th. of September 1891: 343
CYPRIPEDIUM MACROCHILUM,
n. grd. hyb. (Longifolium X Lindenii )
This new production of Messrs. J. Veitch & Sons, and which was awarded a First-class Certificate at the Royal Horticultural Society, on August 11 this year, is one of the most extraordianry which the skill of the hybridiser has yet produced. Using the pollen of the practically pouchless C. (Uropedium) Lindenii on C. longifolium , the unexpected result in the progeny of an extraordinarily large and elongated labellum or pouch, as seen in the illustration (fig. 40) was produced. The plant has the usual bright green leaves of the Selenipedium section of Cypripedium, and the one from which the illustration was taken had a four-flowered scape. The upper sepal is creamy-white, slightly tinges with green, and having greenish lines thereon, the lower sepals are similar to the upper. The petals, which resmble those of C. caudatum, have purple hairs at the base; they are greenish-white, tinged and streaked with rose-colour and deepening in hue towards the tips. The staminode has a fringe of purple hairs, and the labellum which forms the striking feature in the flower is ivory-white, tinged in places with pale green, and the veining coloured, and between them tinged with reddish-brown. The labellum is curved forward, and its unfolded lobes are white, beautifully spotted with rose. In delicacy of beauty, if not in stature, it takes rank above even its ally, the stately and favourite C. grande x (C. longifolium var. X C. caudatum). J. O'B.
