I know nothing of the fertile fronds; the sterile ones are
simple, erect in growth, and oblong-elliptical in form, coriaceous,
attenuated at the base, and being articulated on a densely
scaly rhizoma, the scales wrapping over each other. In the
young state they are nearly white, becoming pale brown w'hen
more mature. The rhizoma is branched and creeping.
L en g th of frond from two to three inches; colour a dull
heavy green.
T h e frond is p re ttily veined, like P olypodium venosum, but
being less tran sp a ren t the veins are not so plainly visible.
Aly thanks are due to Air. Henderson, of AVentworth, for a
nice plant of P . squamulosum.
I t is in the T e rn Catalogues of R. P a rk e r, of Hollow'ay;
Booth and Son, of H am b u rg ; and Kenn ed y , of Covent Garden.
T he illustration is from a plant in my own collection.
