Balantiopsis diplophylla
(Hook.f. & Taylor) Mitt.Procumbent, pale green to rose pink. Stems with occasional branches; branches emerging from stems laterally beside leaves without ventral lobes, or branches emerging ventrally and not associated with an underleaf of reduced width. Leaves contiguous to imbricate, obliquely to widely spreading, the ventral lobe gently curving away from the stem; ventral lobe elliptic to broadly elliptic, 550–2100 μm long, 350–1375 μm wide (not including cilia), with 7–12 cilia ending in a single row of up to 5 cells, attached to dorsal lobe by an arched keel 150–625 μm long; dorsal lobe oblate, elliptic, orbicular, 375–1625 μm long, 250–1300 μm wide (not including cilia), with 7–11 teeth, most cilia-like and terminating in a single row of up to 4 cells. Underleaves ovate to broadly ovate, bilobed to 1/2 of the underleaf length, 625–1625 μm long (not including decurrencies), 275–1250 μm wide (not including cilia), with 6–18 cilia below apical lobes, some emerging from lobules, imbricate; lobes triangular, oblong or rectangular, with 3–5 cilia. Leaf cells polygonal to oblong, in apical parts of leaf lobes 17–60 μm long and 12–28 μm wide, becoming more elongate to 112 μm long toward base, firm-walled and evenly thickened throughout, smooth to minutely striolate-papillose, with 2–5 oil bodies; oil bodies ovoid, spherical, fusiform or ellipsoid, hyaline to smoky grey, granular.
OtP, GGr, EGL, WPro, HSF, HNF, OtR, Strz, VAlp. In higher rainfall regions of Victoria, including the Grampians, Otways, Yarra Ranges, Strzelecki Ranges, Wilsons Promontory and East Gippsland, where it usually grows on moist embankments of tracks and creeks. Also, Queensland, New South Wales, Tasmania and New Zealand.
Balantiopsis convexiuscula and B. rosea have also been reported for Victoria. However, Victorian records of these species do not seem to match New Zealand plants of these species in key diagnostic features such as cell size for B. convexiuscula, and in cell papillosity in B. rosea (Engel & Glenny 2019). Consequently, all non-alpine Balantiopsis is here included within B. diplophylla.
