68 Transactions. — Botany. 



cellular, forming a narrow cup, sharply laciniate, white with 

 pinkish bases, enclosing 8-10 sub-cylindrical sacs. 



Hab. Among other ■Hej^aticcB and overrunning them, on 

 decaying logs ; woods south of Dannevirke, County of Wai- 

 pawa; 1888: W. G. 



Obs. A species very near M. cohnsoanwn, Mitt., but differ- 

 ing in colour, and in form of leaves, stipules, and cells : also, 

 near to M. amcenum, Col. ("Trans. N.Z. Inst," vol. xix., 

 p. 288), but dilfering in colour and position of leaves, and 

 largely in form of stipules and of cells. A very pleasing little 

 species. 



Genus IG. Isotachis, Mitten. 



1. I. clegans, sp. nov. 



Plant small, erect, fin.-lin. high, stem short irregular 

 simple and 1-branched with innovations ; leafy throughout ; 

 the leaves larger close and imbricate at top, smaller and more 

 distant below ; green when young, reddish mature. Leaves 

 ■ sub-oblate-orbicular (in outline), the top almost bifid, and 

 two large shallow lateral sinuses, margins irregularly and 

 distantly lacinio-denticulate ; teeth coarse and variable. Sti- 

 pules sub-quadrate, bilobed, the sinus reaching nearly to the 

 middle and very broad (larger than lobes), extending quite 

 across, the two corners prominently horned and directed out- 

 wards ; base sub-cordate and sub - amplexicaul ; margins 

 irregularly and slightly distantly denticulate. Cells large, 

 clear, and sub-elliptic, their walk double. 



Hab. On the ground among other small HcpaticcB and 

 ScliizcBa australis, sides of Mount Tongariro, County of East 

 Taupo ; 1887 : Mr. H. Hill. 



Obs. A pretty species, nearly allied to a Tasmanian one — 



1. gunnii, Hook. f. 



2. I. Montana, sp. nov. 



Plant small, tufted, reddish-brown, erect, fin.-lin. high, 

 very slender, simple, sometimes forked at base ; stem flexuous, 

 with 2-3 innovations, tips nodding, hairy about bases. Leaves 

 alternate, distant (close and imbricated at innovations), orbi- 

 cular-quadrate (outline), 3-fid ; lobes short, triangular, acute, 

 concave, recurved ; sinuses broad, margins sub-sinuate, some- 

 times a fcAV minute blunt teeth at basal portion. Cells small, 

 compact, orbicular, with minute cellules between them, larger 

 and parallelogrammatic at centre and base. Stipule free, 

 between leaves, small, sub-orbicular, bifid, margins more 

 irregular, with a few minute teeth. 



Hab. Among other Hepaticca and small mosses, on the 

 ground, slopes of Mount Tongariro, County of East Taupo ; 

 1887 : Mr. H. Hill.
