Temnoma townrowiorum

Terrestrial or lithophytic, brown, bright green toward stem apices, dioicous with male plants more slender, with smaller leaves and fewer and shorter cilia. Branches arising from main stem abaxial to modified lateral leaf with fewer lobes. Leaves 4-lobed, obtrapezoidal to obdeltoid in outline, 225–800 μm long, 300–1075 μm wide (not including cilia), transverse to weakly succubous in insertion, widely patent, concave adaxially, ciliate, cilia on reflexed sinus base projecting perpendicular to leaf plane; lobes with a triangular to ovate base, 0.3–0.7 (–0.8) the length of disc, 4–12 cells wide at base, ciliate, abruptly contracted at apex to much longer cilia up to 7 cells long; disc 6–14 cells long, 19–45 cells wide. Underleaves slightly smaller than lateral leaves, 75–650 μm long, 150–825 μm wide, otherwise similar. Leaf cells elongate-polygonal to oblong, becoming isodiametric in lobes, 17–68 μm long, 14–30 μm wide (excluding terminal acicular cell), most elongate and rectangular in cilia, where 40–150 μm long and 12–25 μm wide, striolate with numerous small papillae, firm-walled, with (2–) 4–6 (–8) oil bodies; oil bodies spherical to ovoid, homogeneous. Bracts larger than vegetative leaves, otherwise similar; lobes usually with 3–5 pairs of cilia. Perianth cylindric, trigonous, with a ciliate mouth.
