Dna And Morphology: Comparisons In The Onagraceae, Kenneth J. Sytsma, James F. Smith
James F. Smith
Comparisons of systematic information generated from both classical systematic approaches and from DNA analysis at a number of taxonomic levels in the Onagraceae are presented. Phylogenetic results from chloroplast DNA restriction fragment analysis is in Clarkia sect. Syrnpherica (= Peripetasma) are not entirely congruent with results from morphology , but are congruent with distribution of duplications of isozyme-coding loci. Chloroplast DNA and nuclear rDNA evidence for the origin of the monotypic genus Heterogaura from within the genus Clarkia is discussed with respect to morphological divergence between the two genera. Detailed chloroplast DNA restriction site mapping within the seven diploid sections …
