Abstract

A parsimony analysis was conducted on 319 rbcL sequences, comprising 242 from 194 genera of Leguminosae and 77 from other families. Results support earlier conclusions from rbcL and other molecular data that a monophyletic Leguminosae is part of a Fabales that includes Polygalaceae, Surianaceae, and the anomalous rosid genus Quillaja. Within legumes, results of previous analyses were also supported, such as the paraphyletic nature of Caesalpinioideae and monophyly of Mimosoideae and Papilionoideae. Most new data (74 sequences) were from Papilionoideae, particularly Phaseoleae, Millettieae, and allies. Although the overall topology for Papilionoideae was largely unresolved, several large clades were well-supported. The analysis contained a large sample of Phaseoleae and Millettieae, and not surprisingly showed both tribes to be polyphyletic, though with all taxa except Wisteria and allied Millettieae belonging to a single well supported clade. Within this clade was a strongly supported group that included Phaseoleae subtribes Erythrininae, Glycininae, Phaseolinae, Kennediinae, and Cajaninae, with only the last two being monophyletic. Desmodieae and Psoraleeae were also part of this clade. The monophyletic Phaseoleae subtribes Ophrestiinae and Diocleinae grouped with most Millettieae in a clade that included a group similar to the core Millettieae identified in other studies. All but one of the remaining Millettieae sampled formed an additional clade within the overall millettioid/phaseoloid group.
