Chromosome Polymorphism and Bivalent-forming Triploid and Tetraploid Tradescantia pallida (Commelinaceae).

CYTOLOGIA, 1998
Karyotypes and meiotic chromosome pairing were studied in natural autotriploid and autotetraploid Tradescantia pallida. At both ploidy levels chromosomes appeared as metacentrics, being larger at the triploid than at the tetraploidy level (9.6-15.3 μm and 7.5-10.0 μm, respectively).T. pallida exhibits polymorphism with respect to number and position of
