JUNGERMANNIA DECIPIENS. 
(TAB. L.) 
Jungermannia, surculo erecto, flexuoso, subsimplice : foliis inferioribus minoribus, ovatis, integer- 
rimis ; superioribus rotundato-ovatis, seu subquadratis, dente uno alterove, sparso, spiniformi. 
Hab. Rocks on heathy places about Bantry. Miss Hutchins. 
Plant growing in dense tufts of small size. 
Root large, creeping, of a ligneous texture and brown color, throwing out here and there 
small opaque fibres. 
Stems erect, filiform, flexuose, from half an inch to an inch and a half in height, and 
about the thickness of horse-hair, simple or rarely divided at the base : sometimes, 
however, two or more arise from the creeping root : they are of a rigid and somewhat 
brittle texture ; below of a dark brown color, and opaque ; above of an olive-green, and 
evidently cellular. 
Leaves alternately and rather distantly disposed in a bifarious manner: those at the base 
smallest, most widely placed, not more than a quarter of a line long, ovate and concave, 
with entire margins, and either appressed to the stem or erecto-patent : the rest are 
considerably larger, though they frequently again diminish in size as they approach the 
extremity, and are of a roundish or even a subquadrate figure, patent, and sometimes 
recurved, as in J. spinulosa and J. asplenioides ; their base is decurrent ; their margins 
furnished with one, or often two or three large, and, at their base, broad, spiniform teeth; 
but these are placed in so irregular a manner, and at such uncertain distances, that it is 
not possible to find two that precisely agree in this particular. A common appearance of 
the lower leaves is given at f. 10 : /. 4 is a portion of the stem, of which one leaf has two, 
and the other three, teeth at the apex : /. 5 has an acute tooth at the extremity, and 
another lateral one : /. 6 represents two leaves, the one having its margins entire, the 
other furnished with an obtuse, lateral tooth, which is not of common occurrence: /. 7 
has two divaricating teeth at the apex : /. 8 is cut into two unequal lobes, (which may 
probably have been the effect of accident) the one having two terminal teeth, the other.
