12. C. compacta, sp. nov. 



Plant small, sub-erect, fin.-liu. long, 1^ lines wide, mostly 

 simple, sometimes *2— i branched ; branches short, tips re- 

 curved, leafy throughout ; pale-green. Leaves sub-opposite, 

 closely (one-third) imbricated above, less so below, sub-rotund 

 and sub-orbicular-quadrate, margined, entire ; tips broad, sub- 

 sinuate, and slightly sub-emarginate. Cells large, orbicular, 

 clear, with minute cellules in their angles. Stipules small, 

 free, distant from bases of leaves, broadly ovate, 4-laciniate 

 toothed ; teeth flexuous, sharp, a middle one very long. 



Hah. On the ground in wet woods in the interior, Taupo, 

 &c., forming pretty large compact patches. 



13. G. dicyclophora, sp. nov. 



Plant small, sub-erect, fin.-lin. long, ^ line wide, simple, 

 and slightly branched ; of a pleasing green, with yellow re- 

 curved tips. Leaves densely imbricate, recurved, semi-rotund ; 

 anterior margin arched and with apex toothed, 10-12 blunt 

 teeth ; posterior margin produced at base, forming a complete 

 circular dot-hke auricle, which is doubled. Cells large, 

 orbicular, walls thin with minute interstitial cellules in 

 angles, also obscurely beaded. Stii^ules distant, narrow (sub- 

 linear), reniform, clasping, with a hollow circular centre show- 

 ing the stem, their ends free, obtuse, each terminating in a 

 complete circular dot like those of leaves. Perigonial leaves, 

 near base, sub-fiabellate, erect, toothed, with linear, brownish, 

 antheridia in threes, within a sub-campanulate receptacle with 

 fringed margins. 



Hab. Low wet woods, Danuevirke, County of Waiiiawa ; 

 1888 : W. a. 



Obs. A curious and pretty plant, nearly allied to C. 

 cymbaliferus, Hook. f. and Tayl. 



Genus 11 (1). Tylimanthus, Mitten. 

 1. T. novce-zealandicz, sp. nov. 



Plant gregarious ; root creeping, long, stoutish, simple, 

 naked. Stems sub-erect and drooping, 3in.-4in. high, simple, 

 and few-branched ; stipe lin. long, bare below, with distant 

 small leaf -like scales on its upper part ; branches long, l^iu.- 

 2|in. (sometimes two together from one base), 4-5 lines wide, 

 linear, drooping, leafy throughout ; pale yellowish-green. 

 Leaves alternate, pinnate, very membranous, wavy and ob- 

 liquely set, distant and small on lower part of branch, in- 

 creasing in size upwards, close above, and sub-imbricate in 

 middle of branch, semi-cordate-ovate, dimidiate, 3 lines long, 

 2 lines wide at broadest part near base, with several small 

 marginal plaits ; decurrent on dorsal side, their basal ends 

 crossing; margins finely serrated, the basal portions entire.
