On sandy banks of streams in woods.
Tufts wide, dark green; stems about i inch
high, sparingly branched, curved at the top. Leaves
convex towards the anterior margin. Dillenius
distinguished this from P. asplenioides. It may be
recognised by the obovate leaves, which have no
appearance of being truncate at the tips ; by their
being more crowded, nearly vertical, dentate
throughout ; by both their margins being recurved,
and thence appearing convex in front, by their less
patent position, by the greater length of their decurrent
bases, very essentially by their smaller
cellules ; and by the mouth of the calyx having
large crenulations, which are themselves denticulate.
Besides the tufts are of a darker green, and the
shoots more slender.— Taylor.
