Members of the Artemisia tridentata complex (ASTERACEAE: Anthemideae: Artemisia subgen. Triden- tatae) have adapted to changing environmental conditions through geographic migration, introgression, and hybridiza- tion. These processes have resulted i

Purshia spp. (Rosaceae) comprise a widespread western North American species complex that is impor- tant as landscape dominants, wildlife habitat, browse for wild and domestic ungulates, and seed reserves for small mam- mals. This study examined aspe

This article summarizes information on the taxonomy of 'Appar', a perennial blue flax cultivar ( Linum perenne L. [Linaceae]), and characteristics that distinguish it from native Lewis flax ( Linum lewisii Pursh [Linaceae]). 'Appar' apparently origin

When addressing the nature of ecological adaptation and environmental factors limiting population ranges and contributing to speciation, it is important to consider not only the plant's genotype and its response to the environment, but also any close
