9. Genus Jungermannia L. ex parte

Jungermannia grandifolia (Berggr.) comb. nov. Text-fig. II, Fig. 19.

Lethocolea grandifolia Berggr. N.Z. Hep., 26, 1898.

Symphyomitra grandifolia Steph. Spec. Hep., ii, 167, 1906; Hodgson, N.Z. Hep. 5, Trans. Roy. Soc. N.Z., 76, 85, 1946.

Several specimens of this species have been found with a typical Jungermannia perianth, hence the new combination. The perianths are large, to 3 mm, and broad at the apex when mature: mouth deeply 6-plicate, toothed, with the teeth alternating with the ridges. Invol. leaves large, almost circular, deeply concave, free, or adnate with the base of the perianth.

The species can be recognized by the prostrate stems ventrally clothed with long rhizoids, and the large rounded, regularly alternate, sometimes undulate, concave leaves.
