58 Transactions. — Botany. 



(both sides) deeply laciniate and finely toothed, the basal 

 anterior margin distantly lacinio-ciliate, their sinuses broad 

 and curved, the basal posterior margin entire ; dorsal lobe 

 half as long, tip acute, its basal anterior margin much arched, 

 produced beyond margin of leaf and very minutely serrulate, 

 sub-auricled and largely overlapping on stem, auricles sub- 

 erect and recurved ; the posterior margin considerably within 

 the margin of the ventral lobe ; both lobes a little plaited 

 diagonally. Cells of various sizes, oblong-orbicular not clear, 

 walls thick, smaller and distinct at margins. Stipule large, 

 orbicular (in outline), 2 lines diameter, bifid two-thirds of 

 depth, the basal portion plaited, each segment truncate, sub- 

 tripartite (2-lobed on the outer and 1-lobed on the inner 

 margin), edges recurved, largely lacinio-ciliate ; lacinia3 curvi- 

 form ; sinuses large, rather broad, their laciniac and ciliae 

 crossing each other and them. Cells oblong-orbicular, clear, 

 their walls very thick.

Obs. A fine species, having affinity with G. apj)endiculata, 

 Nees, but differing in several particulars, as in size, habit, 

 short stipe, and being leafy to base ; the leaves narrower and 

 plaited ; the ventral lobe having shallower laciniae in the 

 upper portion, and deeper and curved ones in the lower 

 anterior margin ; the dorsal lobe more produced, minutely 

 serrulate, and auricled ; the stipules, also, larger, more 

 divided, and lacinio-ciliate. 



Genus 8. Chiloscyphus, Corda. 



§ 1. Leaves opposite, stipules united to both the leaves 



below them. 

 1. C. epihrya, sp. nov. 



Plant large, creeping, 3in.-3-|in. long, 2^ lines wide, simple 

 and branched, usually 3-branched at top, and sometimes these 

 again slightly forked at tip, leafy throughout, very membran- 

 ous, pellucid, delicate pale-green. Leaves opposite, close, 

 imbricate, patent, sub-trapeziform, very broad at base, nar- 

 rowly decurrent, long and diagonal on dorsal surface of stem, 

 tip truncate with one horn at each outer angle, the horns 

 4-celled, spreading, the sinus sub-sinuate and slightly pro- 

 duced not incised, margins delicately thickened. Cells penta- 

 gonal and sub-orbicular, with large clear double walls, and 

 narrow linear interstitial cellules. Stipules large, sub-orbicu- 

 lar, 6-toothed, teeth large, connate with leaves below, the base 

 of stipule hollow and rounded, with many fine rootlets.

 Taupo, and interior.
