While _Dennstaédtia_ is the approved scientific name of this species, the
name _Dicksònia_ has come to be used almost as commonly as hay scented fern
or boulder fern. It is one of our most graceful and delicate species, its
long-tapering outline suggesting the bulblet bladder fern. It delights to
cluster around rocks and boulders in upland fields and pastures and in the
margin of rocky woods. It is sweet-scented in drying. A fine species for
the fernery and one of the most decorative of the entire fern family.
The effect of the shimmering fronds, so delicately wrought, flanked by
evergreens, is highly artistic. Fine-haired mountain fern, pasture fern,
and hairy _Dicksònia_ are other names. Canada to Tennessee and westward.

Var. _cristata_ has the fronds more or less forked at the top.

It is a question whether the sensitive and ostrich fern should be included
in the same genus. They are similar in many respects, but not in all. The
