244 REPORT OF THE CONFERENCE ON GENETICS. 
O. crispum, O. gloriosum, O. luteo-purpurewm, and O. Lindleyanum, 
which all grow together, and, aided by insects, make a grand confusion 
even under Nature’s laws. 
Mr. Rolfe would like all these natural hybrids proved. I admit it would 
be interesting, but we raisers all feel so sure of their parentage that we think 
life too short to do so, as we fear the bad forms we should produce would 
hardly repay the details of the proof, but could we produce fine forms of

them have been proved, a list of which I append :

It may be objected to that I have placed the last five in “ Natural 
hybrids,” but they are manifestly equivalent to them, being possible in
