Two others have three genera in their composition, these, of course, 

 being secondary hybrids. They are : — 



Brassocatlaelia, from Brassavola, Cattleya and Laelia. 

 Sophrocatlaelia, ,, Cattleya, Laelia and Sophronitis. 

 An analysis of the parentage of these trigeneric hybrids may be 

 interesting. Brassocatlaelia includes ten distinct hybrids, seven of which 

 were derived from the intercrossing of Brassavola and Laeliocattleya, one 

 from Brassocattleya and Laelia, one from Brassolaeha and Cattleya, and 

 one from Brassocattle3'a and Laeliocattlej^a. Of Sophrocatlaelia four 

 hybrids are known, two of these being derived from the intercrossing 

 of Cattleya and Sophrolaelia, and two from Laeliocattleya and 

 Sophronitis. The arrangement may seem puzzling at first sight, but 

 a moment's consideration will show that in each case the same three 

 genera are represented, though in slightly different proportions. This 

 brings out the curious fact that the same result may be reached by several
