--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>moderate-sized to robust, fairly weak-stemmed, lax in submersed forms, ± sprawling in emergent froms; golden brown to dark brown; capitulum weakly 5-radiate, branches straight to strongly laterally curved. <b>Stems</b> green to pale brown, superficial cortex only weakly differentiated. <b>Stem</b> leaves triangular-lingulate, 0.8–1.4 mm, spreading to appressed; apex acute to narrowly obtuse, hyaline cells nonseptate and fibrillose near apex. <b>Branches</b> unranked or weakly 5-ranked, straight to strongly curved, leaves moderately elongated at distal end. <b>Branch</b> fascicles with 2 spreading and 1–2 pendent branches. <b>Branch</b> stems green but sometimes reddish at proximal end, with cortex enlarged with conspicuous retort cells. <b>Branch</b> leaves ovate-lanceolate to narrowly ovate-lanceolate, 1.8–3.4 mm; straight to strongly subsecund; weakly undulate and recurved when dry; margins entire; hyaline cells on convex surface with 1–2 free pores per fibril interval, concave surface aporose or rarely with a few wall thinnings in cell ends and angles; chlorophyllous cells trapezoidal in transverse section and narrowly exposed on concave surface. <b>Sexual</b> condition dioicous. <b>Spores</b> 33–40 µm.</span><!--
