Linear regression estimations between allele length means and average values of morphological measurements. Allele length means (independent variable) and average values of morphological measurements (dependent variable) for the following different groups of data points were subjected to linear regression analysis: all Hawaiian mint accessions, Phyllostegia accessions only, Stenogyne accessions only, and accessions representing the four different island groups, Hawai'i, Maui Nui, O'ahu, and Kaua'i. Maui Nui represents a single island complex now separated into Kaho'olawe, Lana'i, Maui, and Moloka'i. Significant P values (P < 0.05) are shown in bold. No adjustments for multiple tests were made (see Methods). |

aFor some corolla tube length regressions, data points for S. kamehamehae were excluded since they were extreme outliers. Likewise, some curve estimations for pedicel length also excluded outlier data points for P. warshaueri. |
