1. H. furfurosum, Hook. f. and Wils. FI. N. Z. ii. 107. t. 88. /. 7. 
Stem procumbent, slender, rigid, slightly arcuate, 1-2 in. long, pinnately 
branched, covered with matted fibrils ; branches rather long, distant, filiform. 
Leaves green or yellowish, squarrose on the stem, suberect on the branches, 
incurved when dry, ovate-cordate, acuminate, somewhat keeled, scarcely pli- 
cate, quite entire or serrate towards the apex ; perichsetial larger, erect, long- 
acuminate, somewhat cilinte. Fruitstalk 1 in. long, smooth, red. Capsule 
pale-brown, cylindric-oblong, cernuous, slightly curved ; operculum beaked, 
shorter than the capsule. — H. unguiculatum , FI. Tasm. ii. 208. t. 176. f. 3. 
(?) H. hastaturn, C. Muell. Synops. ii. 485. 
Northern and Middle Islands : probably common on moist rocks and trunks of trees ; 
Bay of Islands, Cunningham , etc. — A puzzling moss, difficult to discriminate from the two 
following. Mitten, who has paid much attention to the discrimination of the species of 
this section, informs me that the H. hastaturn , C. Muell., may belong to this as well as 
H. Stuartii, for that is very variable. He has less doubt in referring H. unguiculatum to 
the same species. (Tasmania, Australia.) 
2. H. fulvastrum, Mitten in Journ. Linn. Soc. iv. 92 ( Leskea ). Similar 
to LI. furfurosum-, but branches short and close-set, giving a linear outline to 
the frond. Cauliue leaves secund, plaited, those of the branches and branch- 
lets evenly disposed on every side; perichsetial much ciliate. — Mitten, mss. 
Northern and Middle Islands : probably common, Auckland, Knight , Bolton , Kerr, 
etc. (Tristan d’Acunha.) 
3. H. sparsum, Book. f. and Wils. Fl.N. Z. ii. 109. t. 89./. 5. Stems 
very slender, matted, creeping, 1 in. long, 2-pinnately branched ; branches 
short, very slender. Leaves dark green, very minute, spreading, incurved 
Avhen dry, ovate or ovate-cordate, subobtuse, quite entire, but rough at the 
edges ; nerve stout, pellucid, vanishing below the apex ; perichsetial much 
larger, long-acuminate, inner laciniate. Fruitstalk ^ in. long, smooth. Cap- 
sule inclined or cernuous, narrow-oblong. Inflorescence dioecious. 
Northern Island, Colenso ; Wangarei, Bolton; Waikehi, Milne. Middle Island, 
Nelson, Travers. This differs from H . furfurosum chiefly in the 2-piunate stems. (Aus- 
tralian Alps.) 
4. H. laeviusculum, Mitten in Ft. Tasm. ii. 207 (Leskea). Stems 
arcuate, regularly 2- pinnate, proliferous from the descending assurgent apices. 
Leaves of H. furfurosum, those of the branclxlets compressed, with incurved 
apices ; nerve cristate at the back ; cauline subcrenulate, with flexuous points ; 
nerve not excurrent, vanishing below the filiform apex. — Mitten in Journ. 
Linn. Soc. iv. 92. 
Northern and Middle Islands: probably common ; Kiapara, Mossman ; Wellington, 
Stephenson ; Milford Sound, Lyall. (Tasmania.)
