lias the pinnae of a lanceolate-acuminate form, and with oblong-
obtusc pinnatifid pinnules, wedge-shaped at the base, the margin
being dentate. The fronds rise out of an erect fasciculate
rhizoma.
The sori, which are linear, arc forked obliquely, becoming,
when fully mature, confluent, and nearly covering the whole
frond.
jNIr. Henderson, of ITentw'orth, has kindly communicated
jdants and fronds of this species. I am also indebted to ile ss rs.
Booth and Son, of the I ’lottbecker N u rse ry , H am b u rg , for
others, and to Mr. Norman, of H u ll, for fronds.
Cr. sulphurea is not common in cultivation; it is in the F e rn
Catalogues of Messrs. A. Henderson, of Fine-apple Place;
Backhouse, of Y o rk ; and Booth and Son, of Hamburg.
This species requires more rvashed sand to be mixed with
the soil than most other F erns, plenty of drainage, and it must
not be allowed to become too dry.
The illustration is from a frond kindly communicated by Mr.
Henderson, of M'cntwoith.
