P e l l æ a W r i g h t i a n a : — Root-stock short, thick, nodose,
densely chaffy with very narrow dark-brown scales; stalks
clustered, dark-purplish or almost black, polished, rigid, four
to six inches long ; fronds about as long as the stalks,
from lanceolate to triangular-ovate in outline, bipinnate ; pinnæ
nearly sessile, spreading ; pinnules coriaceous, smooth,
green above, slightly glaucous beneath, almost sessile, at
most about six pairs ; those of the sterile fronds roundish-
oval, three to five lines long, two-thirds as broad, rounded
or even subcordate at the base, the apex obtuse, but with a
minute subulate semi-pellucid cartilaginous point or mucro ;
those of the fertile fronds rolled in nearly to the midvein, and
therefore very narrow, often longer than the sterile ones and
curved upwards, similarly mucronate.
