Asplenium decurrens, commonly known as shore spleenwort, is a small erect species of fern of the family Aspleniaceae. It is predominantly native to South Eastern Australia and New Zealand.
Description Asplenium decurrens is a herbaceous fern with tufted erect fronds. Fronds are clustered and erect, long and pinnate. Rhizome is erect and stout often forming a hard woody mass, bearing shiny, purplish-brown, ovate translucent scales which taper to long, fine points. Similar scales are found at the base of fronds, and smaller scales scattered on the rachis and midvein ventral surface.
Stipe and rachis are brown and flat at the base, and fleshy green above. Both are sparsely scaly, with scales narrowly triangular. Stipe is long and diameter. Pinnae are in pairs of 2–18, narrowly ovate or narrowly elliptic. Longest pinnae found at or below the middle, gradually reducing upwards till reaching an enlarged terminal pinna. Sori superficial, long with several on each pinna without reaching lamina edge.
Distribution and habitat In Australia Asplenium decurrens ranges from the southeastern coast of Bowen Island, New South Wales, to Lady Julia Percy Island, western Victoria, across the Bass Strait Islands and mainland Tasmania. It is found rarely to inhabit southwestern Western Australia, where it is localised. It is also native to the North Island of New Zealand and to the Kermadec Islands, New Caledonia, Pitcairn Islands, Society Islands, Tonga, Tuamotus, and Tubuai Islands in the South Pacific. { "type": "FeatureCollection", "features": [ { "type": "Feature", "properties": {}, "geometry": { "type": "Point", "coordinates": [ 150.858988, -34.421176 ]
