J. mloyhgUu it swells much in moistening, and assumes a stout and as it were greasy appearance, from the peculiar
texture of the (hstended cells. The broad stipides, reaching nearly across the back of the stem, resemble those
ot / . Billardieri, aud are as regidar and close along the whole plant as the scales ot a snake.

In some respects this remarkably beautifiil species resembles a Gottschea, but it is in reahty more allied to the
genus Seafania of Lindenberg, from whose pubhshed characters it differs only in the presence of stipides ! From
what we have seen of the fructification, however, it widely depai-ts fi-om that group. The caljqitra, in a specimen
from M-Quarrie’s Eiver (New Holland), is globose, destitute of any calj-x, surmounted by a tnincatcd style,
rough with numerous baiTen pistiha on its surface, and siirromided by scales ; the scales are laciniate, the outermost
the naiTOwest, and ah enclosed in a triphyUous perichætium.

We know of no species with which the present can at all be compared. The leaves and stipides are so nearly
alike and so regularly stiff and patent, that the stems look pectinated with a triple row of spines, standing at rcgidar
intervals. This rigidity, combined with the slender habit, is very remarkable.

The figure of this plant, in the ‘ Musci Exotici,' does not well accord with our species, in which the upper margin
of the leaf is more produced into a lobe, the apex blunter and sometimes emarginate or even bilobed, the lower
margin more recurved and the whole base broader.
To this gi'oup may be added the Jungermannia {Acrobolbus, Gottsche) Wilsoni, Nees, and the following.

This species, rather variable in its form, especially of the margins of its leaves, is a native of Tasmania, as well
as of Lord Auckland’s gi-oup and the Straits of MagaDiaens, where it was first detected by D’XJnille.
