Very nearly ¿dlied to I. madida in size, colour, and habit, but with wider and less deeply notched leaves, which
are also more distant and divaricate. The perianth, like that o f/. Lyellii and / madida, is remarkably thick and
fleshy; in the last-named species it is composed of five strata of cells, the roughness on its exterior surface appears
to be caused by the partial breaking up of the external ivaU of ceUs, and resembles that of the calyptra? of the ¿'ar-

These specimens appear to agree in every respect with British examples ; and although Dr. Gottsche has recently,
from the Australian specimens gathered by Dr. F. Mueller, described it as a distinct species, yet the sum of
the characters he has given amount ouly to this,—that the stems are a httle louger, and the perianth a httle shorter,
than in European specimens of Jungermannia obtusifolia, with which he admits that it otherwise agrees : the Tasmanian
specimens, evidently the same species as those from Australia, have not that appearance presented by Dr.
Mueller’s, from his having grown iu a compact tuft. A careful examination of the insertion of the leaves of this
species, as well as of those of Jungermannia albicans, has coiifimied tbe fact, already suspected from the substance of
the leaves themselves, that they belong to that section of the leafy Hepaticæ whose leaves are inserted with the dorsal
angle nearest towards the apex of the stems,—incubons,—in tids particular they are at once removed from Jun-
germannia, and agree with Scapania, excepting that the perianth is not appressed, but contracted at the mouth, contrary
to the characters ascribed to Scapania; nevertheless precisely the same kind of periantli is sometimes produced
by S. undulata, but whatever variations may take place in the form of the perianth, Scapania, with the additions here
proposed, forms a most natural geuus, whose place must be near to Gottschea.

There appears to be no diilereuce, excepting tbe paler colour, to distinguish S. rertebralis from the present, and
the perianth is, as in other species of the geuus, flattened, and at the apex tiuncatc.
