Polystichum formosum Tindale

Broad Shield-fern

Fronds divided 2-3 times, to about 60-70 cm long with papery scales at the base of the stalk; plantlets never present on main axis. Blade triangular in outline, dark green, leathery; stalks long. Segments deeply cut with prickly-looking teeth. Sori pale brown sometimes with a black centre. Indusia soon shed. Can grow in cool areas.

The name P. aculeatum (L.) Schott (which refers to a European species with fronds divided twice and branches gradually becoming shorter to the base of the frond) has been incorrectly applied to this species.

Recognition: Blade broad-based, more or less triangular in outline; plantlets never on main axis.

Australia (Queensland, New South Wales, Victoria).
