Abstract: The endemic seagrass Halophila hawaiiana Doty & Stone is found
in discrete populations throughout the Hawaiian Archipelago. Morphological
characteristics of plants from Midway Atoll, Pearl and Hermes Reef, Kaua‘i,
O‘ahu, Moloka‘i, and Maui were measured and compared. Striking variation in
leaf length, leaf width, leaf length to width ratio, and internode length was evident
among the 18 collection sites sampled at depths ranging from 0.32 to 18 m.
DNA sequence analyses of a chloroplast-genome, single-base repeat locus in
ramets from nine different collections found only two repeat haplotypes. Repeat
haplotypes were fixed at all collection sites and for all islands except O‘ahu.
