SPECIES OR HYBRIDS.—We have been asked whether there is Be 
absolute test between species and hybrids. We must answer, No. Hybrids 
often exhibit certain degrees of sterility, but this seems less common among 
Orchids than in many other plants. A completely fertile hybrid whose 
origin was unknown would pass as a true species, and no doubt often haf 
done so. The late Mr. Borrer once wrote: “If hybrids . . . are so easily 
produced, so often fertile, and so capable of perpetuating their own forms 
as the report of the experiments of . . . seem to prove, the gift of scientific 
divination is indeed needful for determining the species and their products. |
