JUNGERMANNIA SCALARIS. 
(TAB. LXI. ) 
Jungermannia, caule repente, simplice: foliis rotundatis, concavis, integris emarginatisque j 
stipulis late subulatis : fructu terminali ; calyce perichaetio immerso. 
Jungermannia scalaris. Schrader, Samml. " 11 . p. 4. Hoffmann, Germ. n. p. 89? Roth, 
Germ. iii. p. 374? 
Jungermannia lanceolata. Engl. Bot. t. 6 05. 
Hab. Abundant, upon a loamy soil, in woods, barren wastes, and hedge-banks. 
Pi. ant growing in patches, covering a considerable surface of ground ; the individuals generally 
densely crowded. 
Root consisting of small, whitish bundles of fibres, originating from the lower surface of 
the stem, and near the base of the stipules. 
Stems from a quarter to half an inch, or sometimes more, in length, simple, or rarely 
producing innovations, filiform, rather wide in proportion to their length, flexuose, distinctly 
cellular, of a pale green color. 
Leaves more or less closely placed in a distichous manner, patent and horizontal, (f. f. 4. 10) 
or erect (f. 7) : they vary in length from a quarter to half a line, the smaller ones being 
found in general near the base, and at the extremity: they are of a roundish figure, 
concave above, at the base semi-amplexicaul, for the most part having the margin entire : 
but, in some individuals, the whole (f. 8), in others, a few only, placed here and there,, 
without any kind of regularity, >re emarginate at their apices. Their color accords with 
that of the stem : the cellules are small, roundish, sometimes obtusely quadrangular at 
the margin, but not strikingly larger than in the disk of the leaf. 
Stipules (f. f. 9. 12) small, of a widely subulate shape, agreeing in color and texture with 
the leaves. 
Perigonial leaves (f. 5) scarcely differing from the rest, except in having a swollen base, 
anti the lower margin a little incurved on the upper side of the stem.
