Other claims from this paper (9)
- Observation Palisota, Pollia and Stanfieldiella are suggested to each have a single basic chromosome number (x = 20, 16 and 11).
- Observation The third continental African species of Coleotrype has 2n = 36 chromosomes, the same as the other two.
- Observation The basic number x = 15 is supported as the preponderant basic number in Commelina.
- Observation The uncommon basic number x = 13 is reported in four Cyanotis taxa, together with karyotypic differences.
- Observation A second Murdannia species has basic number x = 6.
- Observation Chromosome counts are reported for 32 Commelinaceae taxa.
- Observation Chromosome counts for 13 species and 1 subspecies are recorded for the first time.
- Observation Published chromosome numbers for Anthericopsis and Polyspatha are confirmed.
- Observation The known cytological diversity in Floscopa is extended.
