The sea striped fern ( Asplenium marinum L.) is a species of the genus of striped ferns ( Asplenium ) and belongs to the striped fern family ( Aspleniaceae ).

description

The striped sea fern is a vigorous, perennial plant . The rhizome is crooked and covered with linear-lanceolate, light to dark chestnut-brown scales with a thread-like tip. The evergreen, standing in loose rosettes fronds are 6 to 40 (up to 58) cm long. The frond stem is red-brown and about half as long as the blade. The reddish-brown leaf spindle, green at the tip, is winged green. The frond blade is simply pinnate to pinnate with 6 to 20 (up to 40) sections per side, linear-lanceolate, leathery and glabrous in outline. The pinnate sections are 1 to 4 cm long, egg-shaped to elongated, notched-serrated, with a short-stalked, sitting or sloping, trimmed or broadly wedge-shaped and asymmetrical base and rounded tip.

Per leaflet section there are (two to) six to twelve (up to eighteen) elongated, mostly completely separate, 3 to 5 mm long sori with entire indusium . The egg-shaped spores measure (23 to) 27 to 32 (to 38) µm in diameter. The striped sea fern sporulates from March to November.

The number of chromosomes is 2n = 72.

Occurrence

The striped sea fern occurs in Macaronesia , on the western European Atlantic coast and in the western Mediterranean area. In detail, it is on all main islands of the Canary Islands (except Lanzarote), the Ilhas Selvagens , Madeiras and the Azores and is on the continental Atlantic coast from central Morocco via Portugal, Spain and France to Great Britain (there especially on the west coast the North Sea south to Yorkshire), Ireland and southern Norway, on the Mediterranean on the coasts of Catalonia, the Balearic Islands, southern France, Corsica, northern Sardinia, the Tuscan Archipelago, Monte Circeo in Lazio , Malta and Pantelleria as well as in Morocco, Algeria and the La Galite archipelago belonging to Tunisia . In addition, there are old, unconfirmed information from the area around the southern Italian city of Taranto and Cape Verde .

Shady rocks, grotto entrances and old walls are populated as a site, which are often exposed to the sea spray.

Taxonomy

The Asplenium marinum was in 1753 by Linnaeus in Species Plantarum , Volume 2, page 1081 first published .
