--><p><i>Hymenocallis rotata</i> is known chiefly from the spring runs south of Tallahassee, and is found also along other springs to the east and down the peninsula. Although it may be locally abundant, it is restricted to the immediate vicinity (including ditches and lakes) of the spring runs.</p><!--
--><p>A. F. Clewell (1985) treated <i>Hymenocallis rotata</i> as the sole representative of the genus in the Florida panhandle, concurring with the decision made by R. K. Godfrey and J. W. Wooten (1979). Collections often have been misidentified as either <i>H. crassifolia</i> or <i>H. coronaria</i>, and the name <i>H. floridana</i> has been applied to some specimens.</p><!--
--><p><i>Hymenocallis rotata</i> is a striking species with its large, liguliform, deep green leaves, and flowers with large, rotate staminal coronas. In width, the corona is similar to that of <i>H. coronaria</i>, but it is not chalicelike in shape, and its free tepal tips are widely spreading rather than ascending. In cultivation as a garden ornamental since the seventeenth century, <i>H. rotata</i> seems to thrive in most semitropical areas, especially along the banks of streams or wet ditches.</p>
