Copies of seven species and twenty hybrids of Potentilla (Rosaceae) obtained through experimental hybridization (Notes on Potentilla XXVI.)

Copies of Siberian species Potentilla omissa , P. angarensis , P. approximata , P. tobolensis , P. acervata and P. chalchorum , and Euro-Siberian species P. intermedia were created by experimental hybridization of their putative parents. Besides copies of these naturally occurring species, 20 hybrid combinations of Potentilla , which have mostly not been found in nature, were also obtained.
