Brit. 897. t. 27. H. Mossmanianum, C. Mueller in Bot. Zeit. 1851, 565. 
Common throughout the islands, Colenso, etc. Very variable. Wilson considers the large 
cells at the marginal base of the leaf a good diagnostic character. (One of the most widely 
diffused mosses in the world.) 
26. H. mundulum, Hook. f. and JFils. FI.. N. Z. ii. 112. t. 91./. 1. 
Stem 1-1£ in. long, procumbent, slender, flexuous, pinnately branched ; 
branches crowded, erecto-patent, subrecurved. Leaves very pale yellow, 
rather shining, falcate, secund, circulate, ovate-lanceolate below, narrowed 
to a long slender almost piliferous apex, quite entire ; nerve 0 ; perichaetial 
shorter, erect, acuminate, subserrulate. Fruitstalk slender, ^ in. long, red, 
quite smooth. Capsule ovoid, pendulous, dark red-purple; operculum

Middle Island, Lyall. 
27. H. limatum, Hook.f. and JFils. FI. Antarct. Suppl. 545. Stems 
pinnately branched, $ in. long ; branches short, incurved. Leaves pale 
green or yellowish, shining, crowded, secund, falcate, subcircinate, mem- 
branous, ovate at the base, thence gradually narrowed into long subpiliferous 
points, quite entire; nerve 0; perichaetial elongate, subsquarrose, subserru- 
late. Fruitstalk % in. long, quite smooth. Capsule suberect, cylindrical; 
operculum short, convex, hardly conical, apiculate, red. Inflorescence

Campbell’s Island: on decaying wood, J. D. H. (Tasmania.) 
28. H. pulchelluxn, Dicks. ? Stems very slender, suberect, scarcely 
creeping, sparingly fastigiatelv branched. Leaves lax, more or less secund, 
slightly falcate, lanceolate, tapering from a broader base to an almost pili- 
ferous apex, quite entire; cells at the marginal base similar to the others; 
nerve 0 ; perichaetial erect. Fruitstalk 1 in. high, slender, rising from the 
base of the stem. Capsule nearly erect, oblong, tapering into the fraitstalk, 
slightly curved; operculum conical, beaked. — Wils. Bryol. Brit. 404. t. 25. 
II. nitidulum, Wahlb. 
Middle Island : Canterbury Alps, Sinclair and Haast. — I have queried Mitten’s deter- 
mination of this moss, which differs from the European one in laxer habit, paler colour, 
and longer, less falcate and rather narrower leaves. — Schimper remarks that it is nearer II. 
Muellerianum, but distinct. ( H . pulchellum is a native of Temp. Europe and N. America.)

Stems ascending, slender, f-1 in. high, sparingly fastigiately branched; 
branches subcompressed. Leaves pale yellowish-brown, closely imbricate,
