Abstract

Assesses the genetic diversity and evolutionary relationship between Gelsemium sempervirens and G. rankinii. Results indicated that the two species are sister taxa, each with high levels of diversity, but that G. sempervirens is not a derivative of G. rankinii as previously thought. In addition, both species are diploid. The results of this evidence suggest that the two species likely split in the late Tertiary. The split may have occurred as G. rankinii evolved to swamp environments by losing winged seeds and becoming adapted to seed dispersal by water rather than wind.
