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.
