Asplenium vespertinum

Asplenium vespertinum is a species of fern known by the common name western spleenwort. It is native to southern California and Baja California, where it grows in moist, shady, rocky places, such as the shadows beneath cliff overhangs.

Contents

The leaves grow in dense clusters and are up to about 30 centimeters long. Each is made up of 20 to 30 narrow leaflets with lobed edges. There are a few sori on the underside of each leaflet.

Taxonomy

A global phylogeny of Asplenium published in 2020 divided the genus into eleven clades, [1] which were given informal names pending further taxonomic study. A. vespertinum belongs to the "Diellia subclade" of the "A. trichomanes clade". [2] The A. trichomanes clade has a worldwide distribution. Members of the clade grow on rocks and have once-pinnate leaf blades with slender, chestnut- to dark-brown stalks. A. vespertinum is sister to the rest of the Diellia subclade, whose remaining species are Hawaiian endemics formerly placed in the segregate genus Diellia. There is no clear morphological similarity uniting the subclade. The Hawaiian species presumably represent an evolutionary radiation following colonization from California. [3]

Asplenium anceps is a diploid fern of family Aspleniaceae and one of the ancestors of the ferns that form the trichomanes complex. It lives exclusively in the three northernmost archipelagoes of the Macaronesian region, that is, is an endemic macaronesian fern. Its fronds are leathery and plastic and rachis is very thick, bright reddish brown and is traversed throughout its length of three wings, two on the upper surface to draw a groove and a third on the lower surface which is characteristic and unique to this species, since all other species of the trichomanes complex without. A typical feature of this fern, which he shares with all its hybrid offspring is the existence of a small atrium on the basis of medium and less pinnae directed toward the apex of the blade with one or two sori on its underside.
