--><span class="statement" id="st-undefined" data-properties=""><b>Stems </b>rarely whitish to glaucous, moderately stout to slender, to 8 mm diam., acrid- or slightly sweet-tasting; scales concolored brown or slightly darker near point of attachment, lanceolate-ovate, symmetric, margins entire to erose. <b>Leaves</b> to 70 cm. <b>Petiole</b> usually slender, to 3 mm diam. <b>Blade</b> lanceolate-ovate to oblong, pinnatifid, widest below middle or occasionally at base, to 16 cm wide, leathery to herbaceous; rachis sparsely scaly to glabrescent abaxially, puberulent adaxially; scales lanceolate-ovate, usually more than 3 cells wide. <b>Segments</b> linear-lanceolate to oblong, usually less than 15 mm wide; margins conspicuously serrate; apex obtuse to acute; midrib puberulent adaxially. <b>Venation</b> weakly to moderately anastomosing, some to many segments lacking areoles. <b>Sori</b> midway between margin and midrib or slightly closer to midrib, usually less than 4 mm diam., oval when immature. <b>Sporangiasters</b> absent. <b>Spores</b> more than 58 µm, verrucose, surface projections less than 3 µm. <b>2n</b> = 148.</span><!--

|discussion=<p>Although originally considered a cytotype of <i>Polypodium californicum</i>, <i>P. calirhiza</i> is an allotetraploid involving <i>P. californicum</i> and <i>P. glycyrrhiza</i> (S. A. Whitmore and A. R. Smith 1991) and therefore should be treated as a distinct species. Some individuals of <i>P. calirhiza</i> can be difficult to distinguish from the two parental species (see comments under <i>P. californicum</i> and <i>P. glycyrrhiza</i>); most collections can be identified based on a combination of blade shape, venation pattern, spore size, and geographic distribution. <i>Polypodium calirhiza</i> hybridizes with <i>P. glycyrrhiza</i> to produce sterile triploid plants with misshapen spores.</p>
