Stems irregularly branched, every where more or less clothed with leaves
of a yellowish-green colour. Leaves imbricated, spreading on all sides,
serrated, concave, acuminate, faintly striated, furnished with two rather
indistinct nerves at the base ; those of the stem squarrose, broadly cor-
dato-ovate, curiously contracted at the base of the acumination by a
single undulation on each side : those of the branches spreading or
erecto-patent, ovate, with a similar contraction below the acumination.
Periclmtial leaves nerveless, imbricated, their linear elongated summits
spreading or even somewhat reflexed. Fruilstalk one inch to one inch
