in the two secondary ones : the water-storage tissue and the 

 number of rows of vascular strands show the point very clearly. 

 When a character is present in one of the parents, it may or 

 may not be found in the hybrid : e. g., the leaf of Epidendrum 

 prism(ttocar2nim shows a large amount of crystalline substance ; 

 the leaves of the hybrid Lcdia cinnaharina x E. jn'ismatocarjnnn 

 show these crystals, but not in such great quantity ; the leaves 

 of tlie hybrid Lcelia tenebrosa x E. prismatocarpum, on the other 

 hand, do not show any crystals. In general, if the character of 

 one parent does occur in the hybrid, it is jnuch less developed 

 than in the parent. 



Sections of the leaves of thirteen priiiiar}^ hybrids and their 

 parents were exhibited.
