GrROENLAND, J. — Sur les hybrides du genre jEgilops. Bull. Soc. 

 Bot. viii. 612. 



Hybrids obtained from the artificial fertilization of JEgilops 

 ovata and -M. ventricosa by different varieties of wheat were found 

 rarely to retain theii' hybrid character, but to return almost in- 

 variably to the type of the male parent, and ultimately die out. 

 A natural 'hybrid,' however, (Imown to be such from the circum- 

 stance that its produce was, in part, sterile, with all the character 

 of a Triticum, and in part, true ^gilops triticoides) has jDcrpetuated 

 itself since 1858 ■with a rapid increase of fertility, the last gene- 

 ration, retaining all the hybrid character, having been as fertile 

 as ordinary cultivated wheat.
