JUNGERMANNIA STIPULACEA.

(TAB. XLI. ) 
Jungermannia, caule procumbente, simplice : foliis rotundatis, apice emarginatis, sinu seg- 
mentisque acutis, rectis : stipulis magnis, ovatis, acuminatis, prope basin margine utrinque 
unidentato : fructu laterali ; calycibus obovatis, apice subplicatis ; ore contracto obtuse dentato. 
Hab. Shady rock in Laharn wood, near Bantiy, Ireland. Miss Hutchins. — Found after- 
wards at Lough Bray, by Dr. Taylor ; and in Scotland, by Mr. George Bonn. 
Plant growing in dense, very compact tufts, or cushion-like patches, resembling those of 
J. incisa. 
Roots descending in small bundles from the whole length of the under side of the 
stems, each bundle originating immediately beneath the stipules : most abundantly 
towards the base of the plant. Every individual radicle is simple, whitish, and pellucid. 
Stems procumbent, or occasionally nearly erect, scarcely exceeding a quarter of an inch 
in length, and not more than the fifteenth of a line in diameter, a little flexuose, 
filiform, or slightly tapering from the base towards the extremity, almost always 
simple, though I have observed them, in one or two instances, producing young shoots. 
Their color is a yellowish-green, inclining below to a brown. The cellules are tolerably 
conspicuous under the microscope. 
Leaves (f. 6 ) bifarious, smallest at the base, gradually becoming larger towards the 
middle, where they are three-tenths of a line long, but thence diminishing to the 
apex j they are rather closely placed, and slightly imbricate each other, sometimes 
patent or horizontal, but by far more frequently erect, slightly concave on the upper 
surface, and convex beneath, a little waved, of a roundish figure, cut at the apex 
into a rather deep and acute notch or sinus, of which the segments are likewise 
sharp and strait. The texture is thin and somewhat membranous, the cellules small, 
roundish. The color a pale green, with more or less of a yellow tinge. 
The stipules (f. 8), which are very large, when compared with the size of the p an , 
are ovate, acuminate, plane or but little waved, a little patent or standing out from 
the stem: the margin entire, except near the base, where it is furnished with a 
single tooth, which is, however, occasionally nearly obsolete. They are of a more 
dehcate texture than the leaves, but, in the cellules and color, exactly resemble them.
