EXPERIMENTS IN HYBRIDISATION, &c. 103 
An interesting illustration of this may be seen in the structure of the 
pollinia in the many hybrids between Cattleya and Lelia. 
The genus Cattleya (Lindl.) has four pollinia of equal size, arranged 
in one row, while Lelia (Lindl.) has eight pollinia of equal size, arranged 
in two rows of four each, being generally somewhat smaller than those of 
Cattleya. 
The hybrid genus Lelio-Cattleya x (Rolfe), obtained by crossing these 
two genera, has eight pollinia, arranged in two rows of four each, as in 
the parent Lelia; but in the lower row the pollinia are large and of 
equal size, as in the parent Cattleya, while in the upper row they are 
small, uneven, and apparently rudimentary. In this way the generic 
characters of both parents are inherited. 
Generic characters appear to be more powerful and more lasting than 
either specific or varietal characters, persisting, little changed, for several 
generations, possibly more; and would, no doubt, be much more difficult 
to breed out than either specific or varietal characters. 
For example, Lelio-Cattleya x leucoglossa, raised by Messrs. Veitch, 
is a hybrid of the third generation, whose pedigree may be seen at a 
glance in the following diagram :—
