Lepicolea scolopendra

Epiphytic or lithophytic, golden brown to pale brown, dioicous. Asexual reproduction absent. Stems regularly pinnately branched, without paraphyllia; branches emerging from main stem near a lateral leaf with reduced number of lobes, drooping and curved toward stem base, becoming microphyllous and flagelliform. Lateral leaves usually 4-lobed on stem, becoming 2- or 3-lobed toward branch apices, with central cleft deepest, descending to 0.4–0.7 the length of leaf, narrowest at sinus of lobes then lobes flaring out, 650–2800 μm long, 275–1050 μm wide (at widest point excluding cilia), transversely to incubously inserted, imbricate, obliquely spreading; disc ovate, crenulate by projecting cell walls, dorsal or acroscopic margin with up to 12 cilia, ventral or basiscopic margin often with 1 or 2 short cilia; lobes long-triangular, entire, becoming hyaline and setaceous, terminating in a uniseriate row of elongated cells up to 9 cells long. Underleaves slightly smaller than lateral leaves, otherwise similar. Leaf cells lumens circular to elliptic and 17–38 μm long, 10–20 μm wide in lobes and along disc margins, thick-walled, with massive trigones, striate-papillose, becoming conspicuously more elongate along mid-line of leaf and in cilia and lobe apices, 25–73 μm long and 12–20 μm wide toward central base, and 42–100 (–193) μm long and 7–23 μm wide in cilia; oil bodies 6–11 per cell at base of disc, 2–4 at lobe base, homogeneous, pale smokey grey, subglobose to ellipsoid. Androecia confined to branches, broadening shoot from adjacent vegetative leaves and distinctly trigonous, comprising around 4–6 pairs of bracts; bracts similar to vegetative leaves, but more ventricose and less deeply divided; antheridia 1–2 in each bract or bracteole. Sporophyte terminal on short branches. Coelocaule c. 2.3 mm long and 1.3 mm wide. Capsule 5–6-stratose. Elaters bispiral.
