The frequently reflexed antical lobe is also a good character to
distinguish it from other species ; this feature is somewhat inconstant,
but is usually found on some portion of the stem.
Linnæus founded his Jung, resupinata on the plant described
and figured by Dillenius in his Hist. Muse. p. 491, t. 71, f 19,
which, according to Lindberg, comprises two species, one of which
he named Martinellia gracilis. This, liowever, so agrees with the
description “ acutissime crenatos margines ” as well as with the
figure h, that I follow Dr. Carrington in considering it the true
Jung, resupinata. Scapania resupinata, recorded from several stations
in Staffordshire by Mr. J. E. Bagnall (“ Journ. of Bot.,” March
1896), all refer to Scapania aspera, Müll, et B.

Dioicous (?), forming erect crowded tufts or straggling amongst
other mosses and hepatics ; very large ; of a dark brown colour.
Stems simple or furcate, ligneous, a oross-section showing it to be
oval, the outer layer consisting of one or two rows of dark-red
ligneous cells, inner cells white, somewhat homogeneous ; radiculose,
rootlets short, pale, produced from the postical side of stem.
Leaves distichous, imbricate or approximate, divided to the base
or almost into two unequal lobes, the antical one about half the
size of the postical, erecto-patent to patent (40°), cordate, obtuse
or acute, ciliate-dentate, crossing the stem, slightly convex ;
postical lobe patent-divergent to horizontal (80°), plane or slightly
deflexed, ovate, ciliate-dentate ; at the suture one or two large
cilia are often found, 3 to 4 cells long, 2 cells broad at the base ;
epidermis smooth, cells small, roundish, guttulate, cell-walls thick,
angles thickened.
