simple; the colour of each above a dull green, and in substance
thick and fleshy in appearance; beneath the frond is whitish.
The length of a sterile frond varies from one to two inches,
and of a fertile frond from th re e to four inches.
The fronds rise out of a creeping rhizoma, which is covered
with reddish scales.
Sori ro u n d , in about two irreg u la r rows on each side of the
midrib, are confined to the u p p e r h a lf of the frond.
The veins and costa, being b u ried within the frond, are
almost invisible.
The star-like pubescence is n o t so plainly visible as in the
n e x t species.
I am indebted to the Curator of th e Cambridge Botanic
Gardens, and to Mr. H en derson, of W en tw o rth , for plants; and
to the latte r gentleman; Mr. Sim, of F o o t’s C ray ; and Mr.
Norman, of H u ll, for fronds.
The following N u rserymen include this species in th e ir Ca talogues
;— Booth, of H am b u rg ; Rollisson, of T ooting; A. H e n derson,
of Pine-apple P la c e ; Masters, of C a n te rb u ry ; Veitch,
Ju n ., of Chelsea; Sim, of P o o t’s C ray ; and P a rk e r, of Holloway.
T h e frond for illustration was procured from Mr. Henderson,
