closely imbricated second leaves. Now that fructification has been 
found (only two capsules were met with), there can be no doubt as 
to its generic position. From Gymnomitrium concinnatum and 
G. coralloides it may be distinguished at a glance by the smaller 
size and absence of the creamy glaucous colour and the scariose 
margins of the leaves of those species In our other species, G. 
crenulatum , which approaches it more nearly in size and colour, the 
shoots are more regularly terete, and have a wiry look and cop- 
pery lustre, while the border of the leaf is scariose and crenulate- 
dentate. 
85 . Jungexmannia Nevicensis. Carr. 
Tufts cushion-like, pale green. Exstipulate ; shoots ^ to | of 
an inch long, and not thicker than human hair, creeping and 
entangled at the base, flagelliferous, stem ascending, simple or 
irregularly branched, flexuous, apex curved, lower portion leafless, 
and, like the stolons, devoid of rootlets ; leaves bifarious, alter- 
nate, scarcely broader than the stem, remarkably distant, vaginate, 
upper ones erect, roundish-ovate, lower erecto-patent ovate-sub- 
quadrate, complicate-concave, rounded at the base, apex boat- 
shaped, bidentate, lobes short acute, incurved, sinus acute (about 
one-fourth the length of the leaf), texture thin, the cells large, 
translucent — fructification ? 
Hab. Discovered on moist shelving rocks, near the last spring 
below the summit of Ben Nevis, July, 1875, by Mr. J. Whitehead , 
of Dukinfield. 
Note. — Although conscious how objectionable it is to name 
species from barren specimens, the curious plant, which, through 
the liberality of the discoverer, I am glad to introduce to British 
botanists, differs so much from anything known to me, that I have 
ventured to call their attention to it, in the hope that fructifica- 
tion may be looked for, and its position determined. 
The tufts resemble in size attenuate forms of Jung, catenulata, 
but the vertically patent conduplicate distant leaves, and the 
absence of rootlets on the creeping stolons, distinguish it from that 
and other allied forms. 
In the creeping flagelliferous habit and position of the leaves it 
reminds us of Nardia (JV. Funckii ), but here again the distant 
leaves (nearly half a millimetre apart), the lax areolation devoid 
of trigones, and the weak succulent stems, the cortical layer com- 
posed of large quadrate cells, separate it from all known species. 
The colour is lustreless yellowish-green, stolons, and sometimes 
the foliage, tinged with brown. 
96 . Diplophyllum myriocarpum. Carr. 
Exstipulate, creeping at the base, rnizomatous shoots entangled, 
flexuose, polished, resembling pale-brown horse hair; stems terete 
ascending rigid, interrupted repeatedly, innovant, ramuli springing 
from one or both sides of the old axis, either barren and setaceous, 
or fertile, and with rapidly accrescent leaves. Leaves on the lower 
portion of the shoots and flagella distichous, approximate, erect and
