Soi. du Cap Horn, v, Bot., 233, 1889; Kuntze Gen. Plant. 832, 1901; Fulford in Ann. Crypt, et Phytopath., 123, 1946. Mastigobryum spectabile Steph., Spec. Hep., iii, 455, 1909. Plants robust, in clumps or sprawly cushions, brownish green to dark green. Stems to 8 cm., but usually not more than 6, sparingly branched, apex usually forked, flagelliform branches fairly numerous, shortish to 1·5 cm. Leaves a little imbricate, ca. 3 mm. long and 1·4 mm. broad at base, asymmetrically ovate, a little falcate, mostly deflexed, dorsal bases not or slightly overlapping, apex coarsely 3-dentate, the middle tooth often the largest. Cells in mid-leaf ca. 40 × 20μ, becoming smaller and more quadrate towards the margins, trigones small. Stipules large, to 1·4 mm., quadrate to ovate-quadrate, margins and apex crenate, usually with 2 or more rows of hyaline cells, slightly connate with the leaf on one side. This is the largest of the New Zealand species and can be distinguished from B. adnexa by its large size (usually), and large quadrate stipules with crenate, not toothed margins.
