Other claims from this paper (7)
- Observation Whytockia species have 2n=18 chromosomes, each longer than 2.0 μm.
- Observation The Whytockia karyotype represents the most primitive characteristics in tribe Klugieae.
- Observation The primitive basic chromosome number of Klugieae is x=9.
- Observation The resting nuclei of Whytockia have a complex chromocenter type morphology.
- Observation Chromosomes at mitotic prophase of Whytockia are of the gradient type.
- Observation Karyotype evolution in Whytockia is toward more chromosomes with submedian and especially subterminal centromeres.
- Recommendation Variety wilsonii should be separated from W. tsiangiana as an independent species with affinity to W. bijieensis.
