--><p><i>Eleocharis cancellata</i> is very similar to <i>E. bella</i>. The achenes of <i>E. cancellata</i> are relatively broader in relation to their length, the angles and ridges obscure and fewer, and the trabeculae very distinct and faintly wavy at 35X. R. McVaugh and W. R. Anderson (1974+, vol. 13) mentioned possible intermediates with <i>E. acicularis</i> from Mexico. <i>Eleocharis cancellata</i> has been reported from the flora area from three collections: (1) Texas, Jeff Davis County, A. Brant et al. 2237, 1993, originally identified as <i>E. bella</i>; (2) southwestern Texas or northern Mexico (probably from near San Antonio), Parry & Palmer 912, 1879–1880; and (3) Arizona, Santa Cruz County(?), C. Wright 1937, collected in 1851. Although it was also reported from New Mexico (H. K. Svenson 1929), <i>E. cancellata</i> probably does not occur there (R. McVaugh and W. R. Anderson 1974+, vol. 13).</p>
