Siphonolejeunea nudipes
(Hook.f. & Taylor) HerzogYellow- to lime green patches on twigs and bark, autoicous. Specialised asexual propagules absent. Stems entirely with normal vegetative leaves and bracts restricted to base of perianth or sometimes leaves bract-like along entire stem. Normal leaves ovate to elliptic, 275–775 μm long, 175–425 μm wide, patently spreading or angled slightly toward stem apex, rounded at apex, remote to contiguous, inserted to the inner side of the marginal row or two of dorsal stem cells and stem clearly visible from above, attached to stem by 2 cells; lobe margin crenulate by bulging cells; lobule ellipsoid to obovoid, 185–425 μm long, 130–200 μm wide, inflated, with bulging keel that seamlessly continues line of adjacent lobe margin or lobe margin a curve deviating at an obtuse angle from the keel but without a distinct notch, with free margin inrolled, with 2–5 marginal teeth; teeth directed perpendicular to lobule, all composed of non-elongated cells, the one furthest from stem not obvious, composed of two cells and appearing like a minor protrusion along the margin, with a hyaline papillae between these cells, the other teeth more distinct, unicellular or sometimes the second tooth from the apex with a base of two cells bearing the single apical cell or a single row of 2 cells. Bract-like leaves oblong, elliptic or obovate, larger with narrower, non-inflated, rectangular lobule without or with fewer distinct teeth, to 1050 μm long, to 750 μm wide. Leaf cells polygonal, 12–38 μm long, 12–28 μm wide, thin-walled, without distinct trigones, bulging, smooth. Underleaf divided to 0.5–0.55 of its length into two lobes, 110–250 μm long, 58–165 μm wide, stalked; lobes linear to lanceolate, directed forward or divergent and separated by an acute to right-angled sinus with a rounded base, 1–5 cells wide at base, terminating in a single row of 1–5 cells. Bracts obovate; lobule not inflated and without teeth, gaping from lobe. Perianth pyriform, with distinctly stalked base, 550–1300 μm long, 350–650 μm wide, 5-keeled, cells smooth, with a short cylindric beak to 45 μm long.
VVP, GipP, OtP, WPro, HSF, OtR, Strz. Sporadically recorded from near coastal woodland, swampy riparian forest, wet sclerophyll forest and rainforest from the Otways east and south of the Great Dividing Range. Also, Queensland, New South Wales, Tasmania and New Zealand.
Some plants with abundant perianths have entire stems with leaves that appear like female bracts with lobules that are flatter, narrower and rectangular and with fewer or no marginal teeth. These leaves look like those of Siphonolejeunea elegantissima, but the cells are bulging and smooth rather than each having a prominent papilla like in S. elegantissima. The same plants also have stems with smaller, more typical looking leaves.
