The biosystematics of Arnica fulgens and A. sororia ( Asteraceae).

Research output: Contribution to journal › Article

Abstract

Arnica fulgens and A. sororia are sympatric throughout most of their ranges in NW USA and adjacent SW Canada. These taxa were previously recognized as 2 morphologically overlapping varieties or not very well separated species. A study of their floral and vegetative morphology, using TAXMAP cluster analyses, foliar flavonoid chemistry, reproductive biology, and ecology indicates that they are distinct species. Studies of reproductive behaviour reveal them to be amphimictic and self-incompatible. -from Authors
