Hab. On bark of living trees among other Hepaticæ, often found creeping over Metzgeria: edges of woods near Dannevirke, County of Waipawa; 1888: W. C.

Obs. Its very diminutive size and pure-yellow colour distinguish it well from all other species known to me. It is rather scarce, though from its smallness it may have been often overlooked. A similar small New Zealand species (R. strangulata, Hook. and Tayl.) is given in “Syn. Hepat,” p. 730: discovered by Hooker in 1840, but apparently omitted by him in “Fl. Nov. Zealand.;” differing, however, from this species in several characters.

2. R. lycopodioides, sp. nov.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Plant erect in little tufts, very small, about 2 lines long, 1/30in. wide, simple and 2–3 - branched; branches and main stem all of nearly same length and size, sub-cylindrical. Leaves brownish, alternate, densely imbricate throughout, sub-rotund; tips produced over (or incised at) apex of lobule; lobule broadly oblong, tumid, rather large for leaf, being nearly half its length. Cells orbicular, small, larger at centre and base.

Hab. On branchlets of living trees among other Hepaticæ and mosses; woods near Dannevirke, County of Waipawa; 1888: W. C.

Obs. A most peculiar-looking little species; differing widely from all others known to me; resembling the tiny narrow spike of a small Lycopodium, or a minute catkin of some amentaceous or coniferous plant.

3. R. albipes, sp. nov.

Plant minute, sub ¼in. long, creeping, thickly overrunning, branched, stems cellular; light-green. Leaves alternate, broadly oval, close, but not imbricate, margined; lobe obovate two-fifths of length of leaf. Perichætial erect, sub-apiculate. Cells orbicular, compact, sub-longitudinally ranged in regular lines. Perianth pedicelled, free, campanulate; mouth slightly denticulate. Fruit-stalk exserted, white; capsule orbicular, black-purple; spores oblong and linear-oblong, obtuse, one end generally broader, sometimes slightly curved.

Hab. On branchlets of Epicarpurus microphyllus, Raoul; and on branchlets of Melicytus microphyllus, Col.; woods, Dannevirke, County of Waipawa; 1888: W. C.

4. R. epiphylla, sp. nov.

Plant prostrate, creeping, 2in.–2½in. long, bipinnately branched; branches alternate, long; branchlets short. Leaves of two shapes and sizes: (1) on main stems, close but not imbricate, sub-orbicular, anterior margin and apex rounded, the posterior less so and contracted at base; (2) on smaller
