|discussion=<p>The marginal teeth in the hyaline leaf apices of <i>Hedwigia stellata</i> display the same characters as the apical cell: generally sharply pointed and narrow, with an occasional papilla; in <i>H. ciliata</i> the teeth are broader and often irregularly covered with scattered papillae, especially on their tips. <i>Hedwigia stellata</i> is common in California only in the San Francisco and Los Angeles areas (W. R. Buck and D. H. Norris 1996). The chlorophyllose, generally yellow-brown boundary between the body of the leaf and the hyaline apex is often irregular with short longitudinal lines of pigmented and non-pigmented cells juxtaposed, resulting in a jagged transverse line. In many leaves, the ultimate laminal cells are somewhat darker in coloration just at this boundary. This is true also in specimens of <i>H. detonsa</i>.</p>
