3. Genus Saggogyna Dumortier

Saccogyna Dum. Comm. Bot. 1822.

Plants with the habit and appearance of Chiloscyphus. Stems prostrate, a little branched, branches postical. Leaves succubous, entire, a little decurrent, sub-alternate. Underleaves deeply bifid: both leaves and underleaves often minutely papillose. Marsupium basal cylindrical, sparsely radicellose, crowned with involcural leaves. Calvotra adnate with the marsupium in the lower part, free above, bearing sterile archegonia Androecia spicate on short semi-postical branches, bracts in 4–6 pairs, imbricate, saccate. Antheridia large, solitary.

A small genus, mostly tropical, with one well-known northern species S. viticulosa (L.) Dumort.

S. australis Mitt. Handb N.Z. Fl. Appen. p. 75, 1867; Fl. Nov. Zel., ii, 145, 1855.

Plants dioicous, dingy green (when dry), mostly in depressed, loose mats on earth in bush, and on tree-fern caudices and tree roots. Stems to 3 cm. prostrate, little branched, often with rhizoids. Leaves ca. 1.2 mm, oblong to oblong-ovate, sub-alternate, convex when dried with margins recurved, more so towards the apex, with a triangular effect, minutely apiculate or sub-bidenticulate or obtuse. Cells to 40μ, hexagonal, punctate with minute papillae, trigones small but distinct, triangular. Underleaves free, bipartite, often deflexed, segments lanceolate-acuminate, with or without a small lateral tooth. Marsupium on a very short sub-postical branch, to 3 mm, cylindrical, sparsely radicellose, with a ring of hyaline bidentate leaves at the mouth; seta very long, capsule valves only 2, 2.5 mm long, twisted when dry. Androecia spicate, very small, sub-postical, quite hidden from the dorsal aspect, bracts to 6 pairs, imbricate, erecto-arched, bidentate.
