cauline leaves are the shortest and broadest, with the nerve excurrent,
which is characteristic of the species and together with the less falcate
foliage distinguishes it from H. commutatum, notwithstanding that
Schwaegrichen has lately united them. The large var., growing in
running water, is the H. fallax of E. Bot. and probably of Bridel. H.
falcatum of Schwaegr. Suppl. v. 3. t. 145, seems to be scarcely different
from this.

Trees and rocks, in mountainous countries. Fr. .— This, in many
points, comes near H. filicinum , but differs in being procumbent, in its
loose and straggling ramification, more closely set, shorter, more concave,
broader and more obtuse leaves, with the margin more reflexed, and
quite entire, the nerve broader, of the same colour as the leaf, disappear-
ing below the point : besides all which, the texture of the foliage is
thicker and softer with distinct cellules : whereas in H. filicinum the
leaves are somewhat scariose.— I have remarked, under H. medium, its
affinity to that species.

ovate somewhat acuminate concave entire the margins incurved

oblongo-ovate cernuous, lid conical. Linn. Sp. Pi. p. 1593.
