Rhizome creeping, branches few, covered with brown or black scales with pale, minutely toothed margins. Sterile and fertile fronds different. Fronds to over 1 m long, erect, rough, pinkish at first. Sterile fronds oblong in outline. Segments shortly stalked, the lower ones hardly shorter than the others; margins finely toothed. Fertile fronds longer than sterile ones, rough.
Formerly known as Blechnum procerum (G. Forst.) Sw. which is now considered restricted to New Zealand; it differs in having two-toned and fewer-toothed scales on the axes and, in general, more rounded ends to the segments. A variable species possibly forming natural hybrids with B. minus.
Will tolerate cool conditions.
Extremely dark green leathery segments.
