524 ORCHIDS, 
flowers are borne singly on the apex of the stems, and 
they have broad, ovate sepals 1tin. long, petals a little 
shorter and narrower, and the pouch large, projecting, 
inflated at the base, nearly 3in. long, and coloured salmon- 
red, mottled and veined with a darker shade, almost white 
at the mouth. This plant is difficult to. manage under 
cultivation, having been known to flower only a few 
times in England, although many people have grown 
it. Loam appears to agree with it best; Messrs. Backhouse 
flowered it by planting it in a fissure of the rockery in 
strong rich soil. It is a native of Siberia, in latitude 
58deg., where it grows in open places or in birch woods.
