--><span class="statement" id="st-undefined" data-properties=""><b>Stems </b>decumbent to erect, much branched from base, stout, 10–20 mm diam. (including hardened, persistent leaf bases); scales bicolored, dense, broadly lanceolate to linear, to 6 × 2 mm. <b>Leaves</b> densely tufted, green over winter, persistent after withering; sterile leaves spreading, 3–17 cm; fertile leaves erect, 5–25 cm; hairs small, appressed, cylindric, scattered along grooves of petiole and along costae and costules of adaxial blade surface. <b>Petiole</b> green to straw-colored, dark brown on proximal 1/8 or less, 1–2 mm wide, firm and strawlike, not collapsed; scales bicolored or ± concolored, becoming sparse distally. <b>Blade</b> deltate to ovate-lanceolate, all 2–3-pinnate, somewhat leathery, opaque; hydathodes sunken below leaf surface. <b>Segments</b> of sterile leaves oblong to ovate-lanceolate, bases cuneate, distal 2/3–1/2 of segments crenate to dentate, often somewhat more deeply incised every 2d tooth; segments of fertile leaves horizontal to ascending, strongly differentiated from those of sterile leaves, linear, 3–12 × 1–2 mm; margins of fertile segments revolute, covering sporangia. <b>Sporangia</b> in sori that coalesce at maturity. <b>2n</b> = 60.</span><!--
