Other claims from this paper (18)
- Observation First chromosome numbers recorded for Ranunculus wallichianus, R. subpinnatus and R. reniformis.
- Observation First chromosome number recorded for Clematis wightianus.
- Observation First chromosome numbers recorded for Thalictrum dalzellii and T. saniculaeforme.
- Observation Ranunculus has n=7 and n=8 chromosome series.
- Observation All Ranunculus species studied are higher polyploids.
- Mechanism Aneuploidy and euploidy are asserted to play an important role in Ranunculus speciation.
- Observation The previous karyological analyses of Anemone show two distinct chromosome series, n=8 and n=7.
- Observation Anemone rivularis and A. japonica have 2n=24 chromosomes.
- Observation Naravelia zeylanica and Clematis wightianus are related, given their larger size and the same chromosome number.
- Observation Nigella damascena is a primitive species, indicated by its fewer and larger chromosomes.
- Observation Thalictrum javanicum, T. dalzellii and T. saniculaeforme possess 2n=16 chromosomes; they are perhaps diploids derived from the n=8 series.
- Observation Aquilegia canadensis has 2n=32 chromosomes and may be a polyploid.
- Observation The Delphinium ajacis population is diploid.
- Observation The D. belladonna population is triploid.
- Observation The basic chromosome number in Delphinium may be n=8.
- Observation Ranunculaceae taxa show a wide range of chromosome numbers, from 2n=12 to 2n=46.
- Observation The basic number of the Ranunculaceae family may be n=8.
- Observation Ranunculaceae species are highly variable and polyphyletic.
