hybrids there is clear evidence of biparental inheritance. 

 The relationships, on the whole, are distinctly closer to 

 the seed parent. 



Crinium. (Table C 4) . 



The parents in each of these three sets of Crinums 



are recognized species that belong to the hardy and 



tender groups — G. moorei and G. longifolium to the 



former and C. zeylanicum to the latter. In each set the 



hybrid shows very markedly in each of the designations 

 biparental inheritance, varying in degree in relation to 

 the various unit-characters and unit-character-phases. 

 Occasional individualities of the hybrids are recorded, 

 and excessive and deficient developments are noted rarely 

 in the first and second sets, but not infrequently in the 

 third set. In the first and third sets C. moorei was a 

 parent — in the first the seed parent, and in the third
