A total of 284, 625-cm<sup>2</sup> quadrat samples, containing 6182 short-shoots was analyzed for leaf width, inflorescence number and sex (the latter if determinable). Although leaf widths and reproductive densities differed at the 5 sites, leaf width was consistently greater when reproductive structures were present, and when the number of inflorescences increased. Sex ratios were male-biased for 4 of the 5 sites. Comparisons of leaf widths between the sexes indicated that leaf width constituted a secondary sex character for this species. Female short-shoots tend to have narrower leaves than male short-shoots. This relationship should also be considered when evaluating the significance of morphogeographic and stress-related variation in leaf width for this species.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Observations on the reproductive ecology of <i>Thalassia testudinum</i> (Hydrocharitaceae). 2.
