Systematics Section Mashayekhi, Saeideh [1], Wheeler, Erica J [2], Mcneal, Dale [3], Columbus, J. Travis [4], Pires, J. Chris [5]. Molecular phylogeny of genus Allium (Alliaceae) in North America. The genus Allium (Alliaceae) is distributed over mid-latitude regions from the dry subtropics to the boreal zone. It includes approximately 750 species total, with about 86 species in North America. The main center of diversity extends from the Mediterranean Basin to central Asia and Pakistan. A second center of diversity occurs in western North America. Thirteen subgenera are recognized. Subgenus Amerallium is divided into two clades: New World and Old World. Most of the New World species occur in California (ca. 50 species) and Texas (ca. 14 species). New World species have been placed into eight alliances based on morphological similarities. We tested the monophyly of the eight alliances by analyzing sequences of two nuclear (ITS, ETS) and two chloroplast markers (trnL-F, rpL32-trnL). The results support the monophyly of most alliances (e.g., the A. falcifolium, A. campanulatum, and A. acuminatum alliances). However, some species resolved in unexpected places.
