Stem shrubby, eredt, villous, and clothed with a brown
cracked bark, branching; branches erect, or a little spreading,
thickly clothed with spreading unequal villous hairs. Leaves rigid, cordate, rounded, or sometimes ovate, scarcely
acute, a little cucullate or hollowed, slightly undulate, very
sharply toothed with rigid cartilaginous teeth, which are
very unequal in size, and some of them again toothed,
clothed on both sides with short hairs, underneath strongly
and numerously nerved, the nerves much branched. Petioles
broadly flattened, and furrowed on the upper side, and convex
on the lower, widened at the base, thickly clothed with
unequal spreading hairs. Stipules very broad, cordately
ovate, more or less toothed, villous, and ciliate. Peduncles
cylindrical, thickly clothed with spreading villous hairs, as
are the bractes, pedicles, and nectariferous tube. Umbels
4 or 5-flowered. Involucre of 6 or 7 ovate, acute, concave
bractes, which are sometimes toothed, and close-pressed to
the pedicles. Pedicles long, 2 or 3 times the length of the
nectariferous tube. Calyx 3-cleft, segments very long,
straight, lanceolate, and tapering to a long slender point,
which is tipped with a brown mucro, densely clothed with
villous hairs. Petals 5, ovate, of a pure white; the two upper
