This plant has the dense indument of P. Palmeri and P. arida.
Like P. Palmeri it is a low shrub' with sprawling branches, and is
very viscous. The flowers are smaller, with a shorter gynophore and
proportionately longer outer corona filaments. The leaves are
smaller than in P. Palmeri, and the indument of the stem is densely
matted, almost lanate, not of soft, straight hairs. It is distinguished
from P. arida by its shrubby habit, extreme viscosity, and usually
small leaves with suborbicular lobes.
Dr. I. M. Johnston has supplied the writer with valuable notes,
made from field observations, on the species of this subgenus in
