Estimated age of eight nodes on phylogenetic trees reconstructed with rbcL and trnL+trnL−trnF sequence data using either linearized trees method or NPRS and a comparison of these ages with those obtained by Wikström et al. (22) based on a combined data set of rbcL and atpB

The nodes letters refer to those indicated in Fig. 3 (rbcL) and Fig. 1 (trnL+trnL−trnF). +, clade containing the Agavaceae also includes Hosta, Camassia, and Chlorogalum; ML, maximum likelihood.
