three separate flowers were to be found, with the 
exception of the spur belonging to the labellum of the 
middle flower (figs. 15, 16). 
One of the most common malformations in the

blossom, although truly complex, is, as to its external 
form, less irregular than under natural circumstances.

‘Gardeners’ Chronicle,’ 1850, p. 435, from which the 
cut (fig. 17) is borrowed. 
One of the most singular recorded instances of 
changes connected with fusion of the flowers is that
