Lepidozia obtusiloba Steph., Sp. Hepat. 3: 604, 1909 ( Stephani 1909).

Type:— Nova Zeland (ins. merid) Westland, top of Otira Gorge, amongst rocky boulders, 2350 ft, 11 Feb 1903, T. W. N. Beckett 301. Lectotype (designated here): CHR585840 ! Isolectotypes: ex herb Levier 4607, G-000149! WELT-H003162 !

Other type-series specimens:— Nova Zeland (ins. merid) Westland, top of Otira Gorge, among rocky boulders, 2350 ft, 11 Feb 1903, T. W. N . Beckett s.n., ex herb Levier 4598. Paralectotype: G-000150! New Zealand, Otira Gorge, Westland, on bark of Fuchsia trees, 2700 ft, T. W. N . Beckett 348, det L. obtusiloba Steph. n.sp. 1904. Paralectotype: CHR585841 !

Nomenclature:— The syntype series of Lepidozia obtusiloba comprises two gatherings by T . W . Naylor Beckett from the upper Otira Gorge , one Beckett 301 from among rocky boulders, the other Beckett 348 from the bark of a Fuchsia tree. Both gatherings have been split, and duplicates now reside in CHR, FH, G, BM , and WELT.

Recognition:— Lepidozia obtusiloba has leaf and underleaf margins crenulated due to bulging trigones between marginal cells, a region of enlarged cells at leaf base indistinct or absent, first two leaf lobes closely spaced, isodiametric terminal cells on underleaf lobes and leaf lobes, no accessory teeth on lobes or underleaves, and a more or less longitudinal-incubous leaf insertion line.

Remarks:— L. obtusiloba is apparently named for the obtuse underleaf lobe apices, which sometimes do appear obtuse. However, closer inspection reveals this is the result of each lobe’s apex being adaxially reflexed, a feature particularly pronounced on underleaves from secondary shoots. This is a characteristic feature of the lectotype and other topotype material of L. obtusiloba .
