Abstract Specialists studying the genus Viola have consistently allied the Hawaiian violets
comprising section Nosphinium—most of which are subshrubs or treelets—with putatively …

The endemic Hawaiian flora offers remarkable opportunities to study the patterns of plant
morphological and molecular evolution. The Hawaiian violets are a monophyletic lineage of …

A phylogenetic study of the genus Viola used internal transcribed spacer (ITS) DNA
sequences for 44 taxa representing many infrageneric groups in Viola plus outgroups …

The phylogenies of allopolyploids take the shape of networks and cannot be adequately
represented as bifurcating trees. Especially for high polyploids (ie, organisms with more than …

We constructed a molecular phylogeny for a clade of eye‐ringed vireos (Vireo flavifrons and
the V. solitarius complex) to examine existing hypotheses of speciation and ecological …

With approximately 525 species, the genus Viola (the" true violets") represents the largest of
25 genera in the predominantly tropical family Violaceae. Wilhelm Becker recognized 42 …

Botanists have long considered the origins of the Hawaiian flora in terms of long‐distance
dispersal from particular source areas. We extensively reviewed phylogenetic studies of the …

The phylogeography of a variety of species has been studied within the California Floristic
Province; however, few studies have examined genetic variation in bird species across the …

The genus Viola (Violaceae) is among the 40–50 largest genera among angiosperms, yet its
taxonomy has not been revised for nearly a century. In the most recent revision, by Wilhelm …

Migratory species that alternate between sympatry and allopatry over the course of an
annual cycle are promising subjects for studies seeking to understand the process of …
