work at present in course of preparation. ‘The description of the other 
hybrids named may well be postponed. , 
It remains to be mentioned that the whole of the experiments detailed 
in the present paper have been carried out at Greenside Nursery, St. 
Andrews, under most favourable circumstances. 
Discussion. 
Mr. Wesser: I should like to say, in regard to the parentage of the 
two Begonias which the doctor used in order to secure the spotted 
hybrids, that this seems to me to be exceedingly interesting, as it is a 
new feature. I should like to know if it is at all probable that the 
parents were mixed in any way, and that this may be a reversion to some 
previous parent. 
Dr. Witson: The Tuberous Begonias, as everybody knows, are com- 
plex hybrids, so you might look for reversion. I am sorry I do not 
know enough about the parent species to say if any of them have spotted 
leaves; but it should be borne in mind that the leaves of B. coccinea are 
certainly spotted sometimes. If anybody has grown it from seed he may 
know whether it is spotted in its early stages.
