Botanical name:
Austroblechnum banksii
Common name(s):
Shore hard fern
About:
An endemic fern known for its unique characteristics has a widespread yet localised distribution in coastal habitats found on both major islands, particularly thriving on wet rocks and in areas where seepage occurs. The narrow, ladder-like sterile fronds can reach lengths of up to 40-50cm, and the dark green, oblong leaflets exhibit a somewhat stiff texture. On the other hand, the fertile fronds display narrower and more widely spaced leaflets, while the overall growth habit of the fern is tufted. This species shows a preference for damp, light soil and grows optimally in cool situations, whether in the open or under light shade, demonstrating its adaptability to specific environmental conditions.
