BRITISH JUNGERMANNIiE. 
(J. albescens.) 
JUNGERMANNIA ALBESCENS 
(TAB. LXXII. ) 
Jungermannia, caule repente, ramoso: foliis distantibus, alternis, valcle concavis, propremodhm 
hemisphericis, emarginatis ; stipulis ovato-lanceolatis, obtusis. 
Hab. Near the summit of Ben Nevis, Scotland. 
Plant growing in large, loosely-matted patches. 
Stems half or three-fourths of an inch in length, creeping, waved, filiform, branched twice 
or thrice in a dichotomous manner, and attached to the ground by 
Radicles, short, simple, and snbpellucid, which descend in tufts from the under side of the 
plant, and particularly near the stipules. 
Leaves rather distantly and alternately placed, very small, of a nearly hemispherical figure, 
their base semiamplexicaul, their apex furnished with a single obtuse notch, having its 
segments somewhat connivent. The texture is remarkably succulent ; the cellules large 
and prominent, like those of J. minutissima, and its affinities. The color a pale green, 
becoming almost white when dry, which has induced me to adopt the name of albescens. 
The stipules are distantly placed : one between each pair of leaves. It is nearly of the width 
of the stem ; of an ovato-lanceolate figure, quite entire. 
The only British specimens I possess of this plant, are destitute of fructification ; and, 
unfortunately, those which I found in such profusion, bearing calyces and capsules upon some of 
the loftiest of the Swiss Alps, are not arrived in this country; so that, however unwillingly, I must 
defer my figures and description of the rest of the plant, till the appearance of a supplementary 
number. Enough, however, is known of the species, to enable me to say, that I consider it one 
of the most decidedly marked in the genus, and that it will rank near J. Francisci, from which the 
much more concave leaves and entire stipules will always distinguish it.
