Abstract

Discriminant analysis of five natural populations of Tradescantia bracteata (2n=12) and T. ohiensis ( 2n=24 ) showed that the two species are distinct in their phenetic characteristics and differ in their ecological preference. A tetraploid hybrid derivative population (2n=24) was found. It is phenetically closer to T. ohiensis than to T. braeteata. Chromosomal variations of populations were also examined.
