Abstract

The somatic chromosome number of 2n = 64 is reported in the Bohemian endemic Pinguicula bohemica and in the spontaneous hybrid between P. bohemica and P. vulgaris (= P. x dostalii). The same chromosome number of 2n = 64 is confirmed in P. vulgaris. Thus, both the species were found to be octoploids. Different theories about the origin of P. bohemica are discussed in detail.
