of the Utah specimens. The subcoriaceous, yet herbaceous
and tender texture of the pinnæ is not less characteristic of
our plant than of the Chilian, and the sori, sometimes sub-
raarginal, sometimes descending far towards the midvein, are
the same in both. In fact, the difference is just about the
same as that existing between the Pellæa pulchella of New
Mexico and the same species as collected in Chiapas. Notholæna
tenera is confessedly very near to N. nivea, from which
it differs mainly by the absence of ceraceous powder from
the under surface of the frond; but Hooker found traces of
the powder in specimens from Bolivia, and has expressed a
doubt as to the distinctness of the two species.
