F irs t b rought into E n g la n d in 1821, and introduc ed by Dr.
"Wallich into the Royal Gardens, Kew, in 1810.
F e rtile and b a rren fronds difierent.
Sterile or b a rren frond sessile, oblong-ovate in form, cordate
at the base, sinuose, with the vascular stru c tu re i)crmanent and
rigid.
F e rtile frond stipitate, pinnatifid, with linear undulated acuminate
segments; margin stout, articulated with the rachis.
Sori circular, oblique, and somewhat irreg u la r, and spread

In the “ Genera and Species of Cultivated F e rn s,” by Air.
Aloore and Air. Houlston, it is mentioned th a t there are several
well-defined forms of this species, two of which are in cultivation
in E n g la n d ; the first has cordate-ovate sterile fronds six inches
in length, and stipitate fertile fronds two feet in length. The
second is a noble p lant, with cordate-oblong pinnatifid rigid
sterile fronds, from th re e to four feet long, b u t it has not
pro d u c ed fertile fronds.
Rhizoma thick, scaly, and creeping.

Curator of the Roya l Botanic Gardens, Glasgow, and to Air.
