Widely distributed in temperate oceans worldwide.
Substantial differences occur in the literature concerning the morphology of the Zosteraceae, especially the reproductive structures. For a discussion of those differences, see C. den Hartog (1970). In summary, the flowers are unisexual, embedded in a spadix, and may or may not each be subtended by a bract or retinaculum. The spadix is subtended by a spathe, and it may or may not be retained within that spathe following fruit production. Spathes are produced on specialized branches (generative shoots), rather than occurring over the entire plant. The generative shoots may or may not contain normal vegetative leaves, but they do contain one or more spathes. The term inflorescence is ambiguous for Zosteraceae, and den Hartog used ‘rhipidium’ instead. In this treatment ‘inflorescence’ is used to include the spathe, spadix, and flowers.
