|discussion=<p><i>Gemmabryum barnesii</i> is similar to <i>G. dichotomum</i>, but the plants produce numerous smaller bulbils in the leaf axils. The bulbils are green when young and brown with age with primordia less than 1/3 the bulbil length. This species is typically found on disturbed soil that dries out following winter rains. The report by A. Vanderpoorten and C. E. Zartman (2002) for Colorado is tentatively accepted here, as <i>G. barnesii</i> has also been found in Utah. Reports from Florida need to be confirmed. The species is most common in Mediterranean climates along the coast of western North America.</p>
