214 FLORA OF TASMANIA. [Musci, by W. Wilson. 
integerrimis enerviis concaviusculis basi flavidis cellulis alaribus vesiculeeformibus, perichetialibus longio- 
ribus erectis, seta breviuscula levi, capsula pendula elliptico-oblonga, operculo longirostri. (Tas. 
CLXXVII. Fig. 2.) 
Has. Trunks of trees: Mount Wellington. (Guan, 51 5.) (Oldfield. On logs and upon the 
ground, Cheshunt, Archer. 
Allied to H. subsimplex, C. Mueller, Muse. Syn. ii. 283, from Trinidad, and of the same pale glossy hue.— 
Leaves less crowded, turned upwards. Capsule larger, pendulous. Male flower smaller.—From H. leptorrhynchum 
it differs in the wider and shorter leaves, which are not at all falcate, and are somewhat scariose.—PrATE CLXXVII 
Fig. 2; 1, portion of branch, with pericheetium and capsule; 2, capsule and operculum :—all magnified. 
$ 7. Foliis distiche imbricatis vel compressis, subenerviis. 
a. Foliis piliferis. 
31. Hypnum extenuatum (Bridel, Bryol. Univ. ii. 484); dioicum, caule elongato rigidulo pro- 
cumbente inordinate bipinnatimque ramoso, ramis nunc simplicibus nunc apice fasciculatis flagelliferis fra- 
gilibus, foliis patentibus ovato-lanceolatis piliformi-acuminatis enerviis, rameis superioribus appressis muticis 
angustioribus, perichetialibus erectis apice capillaceis integerrimis, seta longiuscula levi, capsula ovata 
inclinata. : 
Has. Barren specimens only, growing amongst Dicranum pungens. (Lawrence. (Gunn.) 
DisrRiB. Australia (solitary specimen with capsule, found amongst other species). New Zealand, 
J. D. H. (barren specimens only.) 
After much investigation we conclude (C. Mueller contr.) that H. extenuatum, of Bridel, is distinct from our 
H. crinitum ; or, if not, that Bridel's description is so erroneous as to render identification impossible. The Moss 
here assumed to be Bridel’s species is larger than H. contiguum.—Stem creeping, 3 inches long or more, with short, 
erect branches, often fasciculate with numerous flagelliform branchlets. eaves yellowish, somewhat glossy, more 
decidedly piliferous, but less so than in H. crinitum. Seta 3 inch long, red. 
32. Hypnum crinitum (Hook. fil. et Wils. Fl. N. Zeal. 114. t. 91. f. 4); dioicum, caule procum- 
bente elongato inordinate pinnatimque ramoso, ramis remotis patentibus planiusculis subpinnatis acutis, 
foliis subcompressis erecto-patentibus concavis e basi oblongo-ovata obtusa longe piliferis subserrulatis 
.enerviis, perichztialibus erectis piliferis, seta elongata levi, capsula ovata cernua, operculo conico.—H. 
filiferum, Taylor, MSS. 
Has. On trunks of live trees, near springs, etc: Mount Wellington, Lyall. Yorktown and St. 
Patrick's River. (Guan, 1589, 1669.) Back River Gully and Johnny's Creek. (Oldfield, 68, 99, 158.)

libus patentibus ceteris appressis omnibus oblongis compresso-carinatis subpiliferis integerrimis enerviis, 
seta longiuscula levi, capsula oblonga horizontali, operculo conico-rostellato.—Phyllogonium callichroum,
