TABLE 1 in The Origin and Phylogenetic Relationships of the Californian Chaparral ' Paleoendemic' Pickeringia (Leguminosae)

TABLE 1. Penalized likelihood age and rate estimates for the Pickeringia, Cladrastis, and Styphnolobium crown and stem nodes derived from r8s analyses of matK sequences. Ages are reported in millions of years (Ma) and rates are reported as number of substitutions per site per million years (sub/s/Ma), with standard deviations (std. dev.). Node (*) is defined as the MRCA of Cladrastis kentukea and Styphnolobium affine (Fig. 4). CladeMean age (Ma)Std. dev. (age)Mean rate (sub/s/Ma)Std. dev.
