Phylogeny of Cajanus species depicted as a 50% majority rule consensus tree.

Tree topology was inferred with maximum parsimony via heuristic searches among 1000 trees. Numbers above branches indicate bootstrap support (>50%). The vertical bar indicates the putative projentitor species (two C. Cajanifolius accessions). Tree length  = 2145, consistency index (CI)  = 0.638, and retention index (RI)  = 0.837. The Bootstrap support for the sister relationship between wild-Australia and Wild-India clades (in the absence of the two C. cajan accessions) is 100% (data not shown).
