168 THE ORCHID REVIEW. [May, 1913. 
coloured’ E. kewense. ‘The latter, re-crossed with the original purple 
species gave purple hybrids with a yellow crest (not a purple crest as in E. 
evectum), but re-crossed with the yellow species gave flowers of a reddish 
salmon colour, one, however, being more orange-coloured. When E. 
kewense was self-fertilised the offspring showed a gradation between the 
deep yellow of E. xanthinum through various shades of salmon to cerise 
and light rosy purple. The two extremes were primrose yellow (much 
lighter than E. xanthinum), and clear purple with a white crest touched 
with yellow in the centre. It was explained that primary hybrids are fairly 
uniform in character because the reproductive cells (pollen and embryos) of 
the parent species which unite to form them are uniform, but a hybrid, 
being a mosaic and combining two distinct ancestries, does not form 
reproductive cells of uniform character. Incompatability comes into play, 
and ancestral characters that do not blend are represented in these cells in 
varying proportions, thus giving rise to that marvellous diversity often seen 
among secondary hybrids. A series of quantitative differences was apparent 
in the flowers shown, the colour being represented in very varying 
proportions. Characters or qualities are adaptations, and of varying 
degrees of antiquity, and their stability, acquired through a long series of 
generations, illustrates what may be termed the persistence of specific 
character in organisms.
