--><span class="statement" id="st-undefined" data-properties=""><b>Herbs </b>erect, to 10 dm, sometimes branching from near base, sometimes with ascending branches in distal 1/2+. <b>Stems</b>: internodes 2-lined at first, then terete. <b>Leaves</b> sessile or (distal) subsessile, rarely amplexicaul; blade narrowly oblong or elliptic to oblanceolate, 50–120(–150) × 10–40(–50) mm, base rounded to truncate or subcordate, apex rounded or rounded-apiculate to retuse, gland dots intramarginal. <b>Inflorescences</b> spiciform-cylindric, 3–7-flowered from terminal node, with sessile or pedunculate inflorescences and flowering branches from to 4 proximal nodes. <b>Flowers</b> 15 mm diam.; sepals narrowly oblong, 4–7 × 1–1.5 mm, apex acute to obtuse; petals elliptic-obovate, 5–8 mm; stamen fascicles 4–7 mm; filaments 1/2+ connate; styles 0.8–1.5 mm. <b>Capsules</b> cylindric, 8–12 × 3.5–4 mm, apex obtuse. <b>Seeds</b> 0.8–1.2 mm.</span><!--

|discussion=<p>The absence of laminar glands in leaves is a more reliable characteristic for differentiating <i>Triadenum tubulosum</i> from <i>T. walteri</i> than sessile versus petiolate leaves, which are not always quite sessile towards the inflorescence in <i>T. tubulosum</i>, or sepals, which can be obtuse in both.</p>
