DENNSTAÉDTIA PUNCTILÓBULA[A]

_Dicksònia punctilóbula. Dicksònia pilosiúscula_

[Footnote A: We again remind our readers that the Latin names in small
capitals represent the newer nomenclature.]

Fronds one to three feet high, minutely glandular and hairy,
ovate-lanceolate, pale green, very thin and mostly bipinnate. Primary
pinnæ in outline like the frond; the secondary, pinnatifid into oblong and
obtuse, cut-toothed lobes. Fruit-dots minute, each on a recurved toothlet,
usually one at the upper margin of each lobe. Indusium fixed under the
sporangia, appearing like a tiny green cup filled with spore cases.
