Plenty. If you use your own definition (the 'limits' of 'cross-fertility'

, then numerous examples of 'new life forms' via hybridization/polyploidy in plants have been produced, almost at will, for more than a century. These hybrids are interfertile only with themselves, not with either parent species (or 'kind', if you prefer). In fact, in multiple instances, wild species/kinds were reproduced in the lab through deliberate hybridization.
