Genus 30. Symphyogyna, Mont. and Nees.
1. S. platystipa, sp. nov.
Plant small, stipitate, gregarious, roots shortly creeping, 2–3 fronds together on a rhizome; erect, 1in.–1¼in. high. Stipe slender, pale, sub-rigid, flexuous, flat at top not winged, sometimes once branched near base. Frond broadly reniform, ½in.–¾in. broad, 2-branched; branches short, twice forked; lobes linear, wide, very thin, transparent, bright-green, slightly undulate, margins entire, tips deeply emarginate, nerve scarcely reaching to notch. Cells large orbicular-oblong. Calyptra at base of main forks, three on a plant, sub-peduncled on a small bulbous process, large, broadly reniform, wavy, the ends free not encircling nor adhering; margin entire and slightly sub-sinuate. Within calyptra 12–14 small erect linear pellucid sacs (antheridia), transversely marked in small
squares, their margins minutely constricted at nodes, tips reddish.
Hab. In wet hollows, deep woods south of Dannevirke, County of Waipawa; 1888: W. C.
Obs. A species having affinity with T. flabellata of Hook., “Musci Exotici,” tab. 13 (but not of La Billardiere, “Plant. Nov. Holl.,” tab. 254, an Australian species, which I believe to be very distinct).
