Maximum likelihood phylogeny of combined nrITS and plastid datasets. Parsimony bootstrap scores are above branches and Bayesian posterior probabilities are below. Bolded species names indicate distylous individuals. Branch lengths are proportional to the inferred number of nucleotide changes along them. The length of the branch leading to O. corniculata has been reduced by half.

Maximum parsimony strict consensus topologies from separate nrITS (88 sequences from 76 individuals, 760 sites, 30% pars. informative) and plastid (71 accessions, 2867 sites, <8% informative) datasets. Bolded species names indicate distylous individuals. Parsimony bootstrap scores are above branches and Bayesian posterior probabilities are below. Incongruence occurs in the placement of O. rosea, and in the order of divergence in the Andean lineages.

Bulb and succulent root of a two year old Oxalis macrocarpa (AG49). There are four bulblets on ~1/2 cm stolons; three are visible. The root has begun to contract, noticeable in its folded epidermis. The scale bar is 1 cm.
