|discussion=<p>In plants of <i>Hedwigia ciliata</i> with dense paraphyses extending onto the calyptra, the paraphyses are sparsely papillose and have sharp lateral teeth on one side at the distal ends of some cells. In the eastern to northeastern part of the flora area, the typical facies have vaginula and calyptra that are densely pilose. The hyaline apices are absent to short or to 1/3 the leaf length.</p><!--
--><p>Although the type of <i>Hedwigia ciliata</i> var. leucophaea has apparently been lost, L. Hedenäs (1994) gave formal synonymy for var. leucophaea. W. R. Buck and D. H. Norris (1996) proposed the name H. nivalis for a facies of what was formerly called <i>H. ciliata</i> in the southwestern United States, and for all tropical American material. B. H. Allen (2010) accepted this suggestion. M. Lueth and A. Schaefer-Verwimp (2004) reported var. leucophaea as new to South America and that the two specimens of the variety were collected from the type locality of H. nivalis. The leaves in var. leucophaea are more oblong (less ovate) than in H. nivalis, the acumina are narrower, and the calyptra is pilose. These characters in the flora area are present and variable throughout the range of <i>H. ciliata</i>, especially in areas west of mid-continent.</p>
