--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>small to medium-sized, green to light green, glossy. <b>Stems</b> 0.5–2.5 cm. <b>Leaves</b> ± spreading, lanceolate to ovate-lanceolate, 0.9–1.5 mm; margins serrulate to serrate in distal 1/3; costa subpercurrent; distal medial laminal cells rhombic to rhomboidal, 45–95 µm, walls thin. <b>Specialized</b> asexual reproduction usually present when sterile; axillary gemmae 2–8, elongate, extending beyond leaves, yellow, pink, or green, leaf primordia at apex and lower, laminate. <b>Sexual</b> condition dioicous; perigonial leaves ovate; perichaetial leaves scarcely differentiated, ovate-lanceolate. <b>Seta</b> orange-brown. <b>Capsule</b> inclined 95–180°, brown to stramineous, pyriform, neck 1/3 urn length; exothecial cells short-rectangular, walls sinuate; stomata superficial; annulus present; operculum convex-conic; exostome teeth yellow-brown, narrowly triangular-acute; endostome hyaline, basal membrane 1/2 exostome length, segments distinctly keeled, broadly perforate, cilia short to rudimentary. <b>Spores</b> 16–23 µm, finely roughened.</span><!--

|discussion=<p><i>Pohlia tundrae</i> has linear to oblong gemmae that extend widely from the distal leaf axils and develop in clusters, sometimes densely. The leaf primordia are broadly laminate and flexuose. Lax plants from shaded microsites have narrow pale to whitish gemmae, but plants from more exposed sites have thicker, sometimes reddish gemmae that can appear similar to those of <i>P. drummondii</i>. At high elevations in Yosemite National Park, <i>P. tundrae</i> grows mixed with <i>P. drummondii</i> and the two appear to intergrade, but such intermediate plants have not been seen elsewhere. Occasional plants with very short gemmae can be confused with <i>P. proligera</i>, which typically has smaller, vermicular gemmae with peglike apical leaf primordia.</p>
