--><p><i>Tidestromia carnosa</i> was accepted as a variety by C. F. Reed (1970) and K. R. Robertson (1981). We follow I. M. Johnston in recognizing it as a species. <i>Tidestromia carnosa</i> is distinctive in being glabrous or nearly so, having fleshy stems, yellowish green true and involucral leaves (particularly apparent in the field but membranous on dry material), and involucres formed by the connation of involucral leaf bases, which become indurate and adnate with or without the true leaf base.</p>
