--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>stiff and upright, large; green to pale green to brownish, capitulum large and flat, with a conspicuous terminal bud. <b>Stems</b> pale green, superficial cortex of 3–4 layers of weakly differentiated cells. <b>Stem</b> leaves triangular-lingulate, 1.2–1.4 mm; apex with a deep lacerate split; hyaline cells aporose, efibrillose and often septate. <b>Branches</b> unranked to rarely 5-ranked, branch leaves only weakly undulate, but sharply recurved at the apex, leaves not much elongated at distal end. <b>Branch</b> fascicles with 2 spreading and 2 pendent branches. <b>Branch</b> stem green, cortex enlarged with retort cells. <b>Branch</b> leaves ovate-lanceolate; 2–2.6 mm; straight; weakly undulate but strongly recurved, hyaline cells on convex surface with very large irregular pores (formed from the confluence of several smaller pores) at the cell apex, concave surface with large round wall thinnings in the cell angles; chlorophyllous cells triangular to trapezoidal in transverse section, apex normally slightly exposed on concave surface. <b>Sexual</b> condition dioicous. <b>Spores</b> 22–28 µm; proximal surface noticeably papillose, distal surface smooth or with fewer papillae; proximal laesura more than 0.5 the length of the radius.</span><!--
