Asplenium adiantum-nigrum is principally a Eurasian species and occurs extremely rarely in North America (see M. G. Shivas 1969 and M. D. Windham 1983 for a discussion of the conspecificity of Western Hemisphere and Eastern Hemisphere material). It is an allotetraploid derived from hybridization of two European taxa, A . cuneifolium Viviani and A . onopteris Linnaeus (M. G. Shivas 1969). Hybrids involving A . adiantum-nigrum and other Asplenium species occur in Europe but are unknown in North America.

Taxonomy

provided by Fire Effects Information System Plants
More info for the term: fern

The currently accepted scientific name of black spleenwort fern is
Asplenium adiantum-nigrum L. [5,12,15]. It is a member of the
Aspleniaceae family. Asplenium adiantum-nigrum is derived from a cross
between A. onopteris L. and A. cuneifolium Viv. [1,11,12]. Black
spleenwort fern shows a wide range of morphological variation,
completely overlapping with the typical forms of both parents [12].

Asplenium adiantum-nigrum

provided by wikipedia EN

Asplenium adiantum-nigrum is a common species of fern known by the common name black spleenwort.[3] It is found mostly in Africa, Europe, and Eurasia, but is also native to a few locales in Mexico and the United States.[3][4]

Description

This spleenwort has thick, triangular leaf blades up to 10 centimeters long which are divided into several subdivided segments. It is borne on a reddish green petiole and the rachis is shiny and slightly hairy. The undersides of each leaf segment have one or more sori[4] arranged in chains.[5]

Taxonomy

Linnaeus was the first to describe black spleenwort with the binomial Asplenium adiantum-nigrum in his Species Plantarum of 1753.[6]

A chloroplast phylogeny verified the allopolyploid origin of A. adiantum-nigrum, with A. cuneifolium supplying the paternal genome and A. onopteris the maternal genome.[7]

Native distribution

Asplenium adiantum-nigrum is native to:
Africa
Asia
Europe
Macaronesia
North America
Oceania

In Hawaii, this native fern grows on cinder cones and lava flows,[8] and it is present in Hawaii Volcanoes National Park.[5]
