abstract = {*Premise of the study: Early plant taxonomists formed hypotheses about relationships among taxa based on characters such as morphology and anatomy. Modern systematic methods, based on DNA sequence variation, provide an additional line of
evidence by which to evaluate taxonomic hypotheses. In North America north of Mexico, wild onions (Allium) are represented by 84 native species, 81 of which belong to subgenus Amerallium. Based on morphology, these species have been divided into eight informal taxonomic 'alliances' hypothesized to represent shared evolutionary history among species. The aim of this research was to test the monophyly of these
alliances with molecular phylogenetic methods.
*Methods: We sampled 74 Amerallium species north of Mexico and two Mexican endemics and constructed a molecular phylogeny of subgenus Amerallium in North America based on predominantly non-coding sequences from two nuclear ribosomal
RNA regions (ITS and ETS) and two plastid regions (trnL-F and rpL32-trnL).
*Key results: Most clades are well supported in analyses of nuclear data and when nuclear and plastid data are combined. However the plastid data alone did not
produce a well-resolved or well-supported tree. Morphological alliances were sometimes congruent with groups recovered in the molecular phylogeny, but strict
monophyly was observed in only three of eight alliances.
*Conclusions: We propose an infrageneric classification that recognizes two sections
in New World Amerallium. Because there is substantial incongruence between morphological and molecular groups, we advocate retaining informal alliances rather
than adopting formal subsections until further morphological and molecular analyses can be carried out.}
