Plagiochila fasciculata

Plants deep green, yellowish green or brown. Specialised asexual propagules absent. Stems arching away from substrate; branches common, emerging from stem laterally and frequently next to a narrower leaf especially toward stem apex, often next to a normal width leaf near stem base. Leaves asymmetrically narrow-ovate to ovate-oblong, in mid-stem 1375–2600 μm long (not including dorsal decurrency), 850–2000 μm wide, longer than wide, rounded to truncate at apex, remote to imbricate, spreading obliquely from stem with dorsal margin close to level with stem and curving ventrally away from stem level toward ventral margin and often ventral margin pointing downwards, dorsal margin recurved, ventral margin plane, with 8–20 teeth, terminating in a single row of 2–3 (–5) cells. Underleaves vestigial, filiform or triangular in outline and 2–3-lobed to base. Leaf cells circular, quadrate or oblong, 15–35 μm long, 10–23 μm wide, becoming more longer at basal center and to 43 μm long, thin- to firm-walled, with distinct trigones, thick-walled at margin, usually with 4–7 oil bodies in medial cells; oil bodies ellipsoid, opaque and colourless, homogenous and almost smooth. Androecia mostly in groups of 3–5 clustered at shoot apex, with 5–13 pairs of bracts, each with 2–3 prominent teeth and a single antheridium. Gynoecia at apex of leading shoot or in a cluster like androecia; bracts ovate-oblong to oblong. Perianth obovoid, 2400–3000 μm long, 875–2000 μm wide, inflated, barely compressed; mouth rounded, spinose to laciniate-dentate. Capsule ellipsoid, 6–7-stratose. Elaters bispiral.
