branches ; lobule brown -purple, rather large and prominent, 

 galeate "with a long acuminate depending tip that is often re- 

 curved. Stipules: on main stems, sub-rhomboid -quadrate, 

 deeply bilobed ; lobes divergent, tips acuminate, with 2 teeth on 

 each lobe outside ; on small branches, ovate, deeply bilobed ; 

 lobes lanceolate, entire. Cells minute, orbicular, regularly dis- 

 posed in longitudinal lines. 



Hab. On bark of trees, intermixed with other Hepaticce and 

 mosses; forests, Glenross, County of Hawke's Bay; 1886: Mr. 

 D. P. Balfour. 



Ohs. A species belonging to Section 1, Division **''', p. 536 of

 Nees, and with F. sjnmfera, Hook. fil. at Tayl., but differing 

 from them both in several particulars. 



2. F. delicatula, sp. nov. 



Plant very minute, delicate pale-green. Stems slender, 

 1-1 i inches long, -^ inch wide (including leaves), bipinnate, 

 irregularly and sparingly branched ; branches rather long for 

 the plant. Leaves round (longer than broad), close but not 

 imbricate, margins entire and slightly recurved, basal portion 

 not inflexed ; lobule small, arched, slightly deflexed, tip obtuse, 

 not produced beyond margin of leaf, pale purple. Cells minute, 

 sub-orbicular, crowded, indistinct. Stipules reniform-orbicular, 

 entire, adpressed. 



Hah. Hilly woods at Pohue, north-west from Napier, County 

 of Hawke's Bay ; 1885. (A few fragments, found mixed among 

 larger HepaticcB collected there by Mr-. A. Hamilton.) 



Ohs. A very filiform, delicate, tender plant, remarkable for

3. F. rotundifolia, sp. nov. 



Plant small, erect, not ^ inch high, but growing thickly 

 together in densely-compacted patches ; dark green, but appear- 

 ing blackish together in the mass. 



Stems creeping, 2 inches long, bipinnate, wiry black and 

 bare below, but stout, and of same colour as leaves, and very 

 much branched at top ; branchlets alternate, very short. Leaves 

 very close-set, imbricate, patent, sub-vertical, wavy, recurved, 

 rather opaque, orbicular ; margins entire, but slightly irregular 

 {sub lente) ; basal portion not inflexed, sub-amplexicaul ; lobule 

 small, sub-galeate, same colour as leaf, tip obtuse, not produced; 

 involucral lanceolate, acuminate, very acute, margins entire. 

 Stipules orbicular, with a small broad sinus at apex, which is 

 broadest and rounded at base, and margined ; tips somewhat 

 conniving. Cells very small, sub-orbicular, with numerous 

 exceeduigly minute interstitial cellules. Perianth sub -terminal,
