title: Nuclear DNA content in the genus Hepatica (Ranunculaceae).
abstract: Using flow cytometry, we measured the nuclear DNA contents of all known taxa in Hepatica. Nuclear DNA content of Hepatica falconeri (diploid, crenate leaf lobes) was significantly lower than that of diploid entire species. Among the tetraploid species, crenate species had lower DNA contents than the entire taxon H. nobilis var. pubescens. The DNA content of the tetraploid species was more than double that of the diploid species among the same leaf-type groups.
