Rhizome creeping, tortuous, branched, as thick as a swan’s qmll
or one’s little finger, densely clothed with ferruginous scales on a
deciduous cuticle, the fibrous roots produced chiefly from the under
side. Scales lanceolate or ovate, very much acuminated, crowded,
sometimes peltately attached, at length deciduous, leaving the sui-face
of the rhizome smooth and greenish. Fibres brown, tomentose,
densely matted over the suiface to which the rhizome is fixed.
Vernation circinate.
S tfe s naked, variable in length, often nearly or quite as long as
the frond, sometimes much shorter, and as well as the rachis slightly
grooved in front; at the base articulated with the rhizome.
Fronds from two to eighteen inches long, lateral to the rhizome,
subcoriaoeous, of a somewhat sombre green, paler beneatb; often
triangular-ovate in outhuc when small, varjdug to ovate-oblong and
linear-oblong, the latter hciug the form assumed hy the fuUy developed
condition of the species in its normal s ta te ; very deeply
