An ITS phylogeny of Balsamorhiza and Wyethia (Asteraceae: Heliantheae).
The relationships among the species of Balsamorhiza and Wyethia (Asteraceae: Heliantheae) were examined using data from the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA. The ITS sequences were obtained from nine species of Balsamorhiza and 14 species of Wyethia as well as seven outgroup genera. Five of the outgroup genera were members of the subtribe Engelmanniinae of t...

متن کاملDiploid and polyploid cytotype distribution in Melampodium cinereum and M. leucanthum (Asteraceae, Heliantheae).
Previous chromosomal studies within Melampodium (Asteraceae, Heliantheae) of Mexico and Central America have documented chromosome numbers n = 9, 10, 11, 12, 18, 20, 23, 25 ± 1, 27, 30, and 33. Some species also have been shown to exhibit infra- and interpopulational polyploidy. The presence of cytotype mixtures is especially pronounced in the white-rayed complex, which occurs in the southweste...
متن کاملNew 1F1N Species Combinations in Ophiocordycipitaceae (Hypocreales)
Based on the taxonomic and nomenclatural recommendations of Quandt et al. (2014) new species combinations are made for Ophiocordycipitaceae. These new combinations are compliant with recent changes in the International Code of Nomenclature for algae, fungi, and plants (ICN) and the abolition of the dual system of nomenclature for fungi. These changes include 10 new combinations into Drechmeria,...
متن کاملPhylogeny of Balsamorhiza and Wyethia (Asteraceae: Heliantheae) Using ITS, ETS, and trnK Sequence Data
Balsamorhiza and Wyethia together comprise 24 species native to western North America. All species in the two genera are perennial herbs with large taproots and chromosome base numbers of x 5 19. The species of Balsamorhiza have exclusively basal leaves while the species of Wyethia have cauline leaves (in addition to basal leaves in some species). The relationships among the species of Balsamor...
