Natural logarithm (ln) of species diversity through time based on the tree in Fig. 1, with scoring of additional species that are identical in ITS sequence with species included in the tree [At all ITS sites, A. grayanum (BGB 661) and A. kauense (BGB 773) are identical to Argyroxiphium sandwicense ssp. sandwicense (BGB 657); D. linearis (BGB 516) is identical to Dubautia arborea (BGB 527); D. platyphylla (BGB 524) is identical to Dubautia menziesii (BGB 522); W. hobdyi (GDC 1150) is identical to Wilkesia gymnoxiphium (Char 76.022) (see ref. 9)]. Ages are based on a 15-Ma calibration point for the most recent common ancestor of the Hawaiian silversword alliance and its Californian ITS sister group.
