Nomenclatural Changes In Polemoniaceae, J. Mark Porter
Nomenclatural Changes In Polemoniaceae, J. Mark Porter
Aliso: A Journal of Systematic and Floristic Botany
Recent molecular phylogenetic analyses of nuclear, chloroplast and mitochondrial DNA of Polemoniaceae have prompted a reexamination of morphological data and a reassessment of current taxonomy. These studies prompt several nomenclatural changes in the family. Eight taxa formerly included in Gilia section Giliastrum are transferred to the genus Giliastrum. In addition, two new tribes of Polemoniaceae are recognized.
Phylogenetic Relationships Of Polemoniaceae: Inferences From Mitochondrial Nad1b Intron Sequences, J. Mark Porter, Leigh A. Johnson
Phylogenetic Relationships Of Polemoniaceae: Inferences From Mitochondrial Nad1b Intron Sequences, J. Mark Porter, Leigh A. Johnson
Aliso: A Journal of Systematic and Floristic Botany
The most recent assessments of phylogenetic relationships and diversification in the flowering plant family Polemoniaceae have relied on nuclear ribosomal and chloroplast DNA sequences. We employed the mitochondrial nad1b intron, located within the second transcription unit of the first subunit of NADH dehydrogenase, for phylogenetic inference. Maximum parsimony analysis of these data provided evidence that Polemoniaceae are more closely related to families Fouquieriaceae, Diapensiaceae, Styracaceae, and Primulaceae than to families of the Solananae, where it has been classified. Fouquieriaceae are inferred to be the sister group of Polemoniaceae; however, when indels are treated as additional characters and given twice the …
Aliciella, A Recircumscribed Genus Of Polemoniaceae, J. Mark Porter
Aliciella, A Recircumscribed Genus Of Polemoniaceae, J. Mark Porter
Aliso: A Journal of Systematic and Floristic Botany
Recent phylogenetic analyses within Polemoniaceae have provided evidence that the current circumscriptionof Gilia recognizes and gives taxonomic status to a polyphyletic assemblage of species. As a first step in rectifying this problem, the genus Aliciella Brand (Polemoniaceae) is resurrected and recircumscribed to include Gilia section Giliandra and Gilia subgenus Gilmania sensu Mason & Grant, a monophyletic (=holophyletic) group as here described. Twenty-one recombinations are proposed: Aliciella cespitosa, A. formosa, A. haydenii, A. haydenii subsp. crandallii, A. heterostyla, A. humillima, A. hutchinsifolia, A. latifolia, A. latifolia subsp. imperialis. A. leptomeria. A. lottiae. A. mcvickerae.A. micromeria. A. nyensis, A. pentstemonoides, A. …
