on regeneration have been written ; and an entirely unsuspected 

 power of accommodation in the most highly organised plants 

 has been discovered. 



What the practical interest of the chimaera may be, it is hard 

 to say. The difficulty of its production, and the small number 

 of plants from which results may be expected, will probably 

 prevent its becoming more than a curiosity. We would hesitate 

 to suggest the possibility of a naturally blended tobacco, did we 

 not recognise that the suggestion is scarcely more fantastic than 

 the chimaera itself. 



Apart from all this, it is some satisfaction to know that, after 

 all, Adam was right. He did obtain his hybrid from a graft — by 

 some accident, probably, a bud of purple broom became hollowed 

 out, and into the cavity grew laburnum tissues. And he was 

 to be excused if he did not recognise that his hybrid was 

 no hybrid, but that it was the materialisation of a very 

 ancient myth.
