A. TAMARISCTNA. 

 Stems closely bi-pinnate. 



1. H. furfurosum, Hook /. and Wils. Stems elongate, 



procumbent, scaly, rigid, closely bi-pinnate ; branches 

 slender, attenuate ; stem leaves squarrose, cordate- 

 acuminate, concave, keeled, plaited, nerve vanishing ; 

 those of the branches sub-erect, incurved when dry, 

 ovate-acuminate, apex denticulate, papillate at the 

 back, nerve vanishing ; perichsetial, narrow, acuminate, 

 denticulate. Fruitstalk smooth ; capsule oblong, 

 cernuous ; lid beaked. Les\ea liastata (Hypnum). C. 

 Muell. Near Hobart, on the ground. 



Stems distantly bi-pinnate. 



2. H. unguiculatum, Hook /. and Wils. Allied to the 



preceding species, but more slender in habit. Stems 

 about 2in. long, distantly branched. Stem leaves 

 small, not concealing the stem, spreading, cordate- 

 acuminate, distant, sub-plicate, sub-entire ; branch 

 leaves distant, much bent inward when dry, but not 

 appressed, ovate-acute, concave, smooth at the back ; 

 nerve slender, pellucid, vanishing; perichsetial, piliform, 

 acuminate, denticulate, Fruitstalk lin. long, smooth, 

 capsule oblong, arcuate ; lid beaked. Teeth yellow, 

 longer than in II. furfurosum ; inner peristome reddish, 

 with cilia. Near Hobart, on the ground. 

 Stems scarcely pinnate. 



3. H. Stuartii, O. Muell. Very similar to II. liastata, 



but the stems irregularly branched, scarcely pinnate ; 

 the larger branches stoloniferous. PerichaBtial, sheath- 

 ing, plicate, margin revolute, including very many 

 long paraphyses, nerve excurrent. Capsule pendulous, 

 turgid (swollen), oblong. Teeth, inner, golden, 

 separate, with very short cilia interposited. 

 Frond of linear outline. 



4. H. fulvastrum, Mitt. Similar to H. furfurosum, but 



branches short and close set, giving a linear outline to 

 the frond. Cauline leaves secund, plaited, those of the 

 branches and branchlets evenly disposed on every side ; 

 perichostial, much ciliate. Hook. Handbook. N.Z. PL 

 On the ground, Bellerive. 

 Leaf with long flexuous, slender point, scarcely serrulate. 



5. H. Iceuiusculum, Mitt. Very similar to H. tamariscin urn. 



Leaves of the stem with flexuous points, nerve 

 thick, excurrent ; perichsetial erect, pale, ovate-lanceo- 

 late, much attenuated, flexuous, sub-serrulate. LesJcea 

 Iwviuscula, Mitt. Mt. Wellington.
