sub-vars. (distinguished by colour only). — atropurpureum, upper sepal 

 and base of petals blackish purple, lip deep purple in front ; Bray's, 

 flowers lighter in colour, the usual blackish purple of the upper sepal 

 confined to the mid-vein and shorter veins on each side of it, the inter- 

 spaces being light green ; Daidhier's, upper sepal with central area 

 brownish, merging into green towards the base and apex, the other 

 segments of the flower paler than in the typical Cypripedium Harris- 

 ianum ; hybridum, upper sepal light yellow-green, the veins blackish for 

 two-thirds of their length from the base, the apical third bright green, 

 petals paler and the lip deeper in colour than in the type ; puipurascens, 

 the veins next the lateral margins of the upper sepal bright vinous 

 purple, the colour spreading over the inter-spaces and into the white

The original Cypripedium Harrisianum was raised by Dominy, about 

 the year 1864, at our Chelsea Nursery, where it flowered for the first 

 time in 1869. It is the first Cypripedium raised by hand, and has 

 since been obtained by several operators from the same cross. Among 

 the progenies so raised have originated many of the sub-varieties to be 

 met with in the various orchid collections of Europe. The variety 

 superbum is one of the original seedlings ; it is distinguished by its more 

 robust groAvth, larger leaves and much larger and more handsome flowers.
