Phylogenetics of Darwiniothamnus (Asteraceae: Astereae) – molecular evidence for multiple origins in the endemic flora of the Galápagos Islands
Whether the two growth forms of Darwiniothamnus Harling (Asteraceae) originated from the colonization of a single ancestor is investigated and molecular phylogenies from other plant groups are reviewed to infer the origin of Galápagos endemics.
Classification of Subtribe Conyzinae (Asteraceae: Astereae)
Abstract: Subtribe Conyzinae includes Erigeron, New World Conyza, the North American genus Aphanostephus, and a small group of South American species segregated as the genera Apopyros,
Galax (Diapensiaceae): Geographic Variation in Chromosome Number
More than 850 chromosome counts of Galax urceolata from 460 locations were made and mapped along with most of Baldwin's original counts in order to obtain a clear picture of the geographic distribution of the cytotypes.
A taxonomic conspectus of Phrymaceae: A narrowed circumscription for Mimulus, new and resurrected genera, and new names and combinations
A revised taxonomic classification of Phrymaceae down to species level is presented, based on molecular-phylogenetic and morpho-taxonomic studies, setting a f ramework for ongoing work. In the
