Much ink has been wasted in arguing for and against this theory of hybridity and botanists are still divided in opinion regarding it. Those who favour the theory point as evidence to the facts that the spores are generally abortive, that its fronds are exceedingly variable in shape, and that it occurs only here and there as a chance hybrid might do and always in the vicinity of its supposed parents. Those who believe it to be a distinct species.
