224 FLORA OF TASMANIA. [ Hepatice, by W. Mitten. 
Var. 8; foliis integerrimis. 
Haz. Var. a. Tasmania, Guan.’ St. Patrick's River, 28th October, 1845, Gunn. Near Hobarton, 
M. Hombron. Brown's River Gully. Moist ground, springs: Mount Wellington, J. D. H. Dense tufts, 
on rocks, with P. falcata: Goat Hills, Oldfield. Var. 8. With the first, from St. Patrick’s River, Gunn. 
Cumming's Head, Western Mountains, Archer. 
The description of Dr. Taylor's P. ophisthotona seems to correspond so well with the present species, that it 
may be easily supposed that it is but one of those instances in which Dr. Taylor imposed a name of his own on an 
already described species; but as no specimens so marked by him are in British herbaria, it is impossible to be 
certain if this reference is correct. The form distinguished as var. £ differs in having its leaves everywhere entire; 
in every other respect they agree with those of the denticulate state. The areolation of the leaves is remarkably 
minute for the size of the plant. 
6. Plagiochila Lyallii (Mitten, in Fl. N. Zeal. p. 132. pl. 96. f. 4). 
Has. St. Patrick's and Acheron Rivers, Gunn. 
These specimens are a little larger than those from New Zealand, but have the same habit, and the leaves a 
little more directed towards the ventral side. The figure of the perianth in the plate above quoted represents it 
much too short; in another New Zealand specimen since received, the mature perianth coincides in shape with that 
of P. incurvicolla, represented in the same plate, fig. 2. 
7. Plagiochila fasciculata (Ldbg. Sp. Hep. t. 1).-—P. aculeata, Tayl. Lond. Journ. Bot. 1844, 
p. 578; G. L. et N. Syn. Hep. p. 627. 
Has. St. Patrick's River, 16th November, 1844, Guan. South Huon, Oldfield, Archer. 
The specimens marked P. aculeata by Dr. Taylor in Herb. Hooker, are precisely the common state of P. fasci- 
culata, but amongst the specimens distributed under the name of P. aculeata, some have been found to belong to 
P. Stephensoniana, a species not yet received from Tasmania. P. uncialis, to which Dr. Taylor compared his 
P. aculeata, is a species belonging to the same group as P. fasciculata and P. spinulosa. In Crypt. Antarct. t. 156. 
f. 7, the leaves are represented with teeth on the dorsal margin, which does not appear to be commonly the case, 
however it might have been in the specimen from which the figure was drawn; the teeth too on the ventral side 
are represented too numerous. 
8. Plagiochila deltoidea (Ldbg. Sp. Hep. Plagiochila, p. 132. t. 27; G. L. et N. Syn. Hep. 
p. 55). 
Has. Tasmania, Zebillardiere. 
9. Plagiochila strombifolia (Taylor); caule repente, ramis adscendentibus vage ramosis, ramulis 
elongatis supremis fasciculatis, foliis imbricatis semiovatis convexis deflexis obtusiusculis breviter decurren- 
tibus patulis, margine ventrali rotundatis apiceque parcius insequaliter dentatis, dorsali rectis subinflexis 
integerrimis vel ad apicem denticulatis, fructu in dichotomia, perianthio ovato, ala nulla, ore dentato.— G. I. 
et N. Syn. Hep. p. 655. Jungermannia strombifolia, Tayl. Lond. Journ. Bot. 1844, p. 578. (Tas. 
CLXXVIII. Fig. 4.) ; 
Has. Tasmania, J. D. H., Gunn, Oldfield. 
Sordide fusco-viridis. Caulis bi-quadriuncialis, dichotome ramosus. Folia patula, late ovata, obtusa, margine 
ventrali apiceque dentibus brevibus spinosis remotiusculis dorsali recurvo integerrimo, involucralia conformia denti- 
bus numerosioribus validioribusque munita. Perianthium elongato-oblongum, ore compresso, labiis rotundatis sub- 
truncatis dentatis.  Spicis masculis elongatis, foliis saccatis imbricatis apice patentibus bidentatis. 
Resembles P. deltoidea in appearance, but its leaves are less deltoid, and more of an ovate outline, and the 
teeth are more spinous; the perianth too is of a different form, and there is no dorsal wing.—PrATE CLXXVIII.
