Asplenium ruta-muraria is a species of fern commonly known as wall-rue [1] (but which, as a fern, is not by any means closely related to common rue). It is a very small epipetric species, growing exclusively on limestone and other calcareous rocks. Its fronds are bluish-green and are heavily sub-divided, becoming up to 12 cm in length.

Taxonomy

Linnaeus first gave wall-rue the binomial Asplenium ruta-muraria in his Species Plantarum of 1753. [2]

A global phylogeny of Asplenium published in 2020 divided the genus into eleven clades, [3] which were given informal names pending further taxonomic study. A. ruta-muraria belongs to the "Pleurosorus subclade" of the "Pleurosorus clade". [4] The Pleurosorus clade has a worldwide distribution; members are generally small and occur on hillsides, often sheltering among rocks in exposed habitats. A. ruta-muraria is exceptional within the subclade for its lack of hairs on the leaf. The phylogeny suggests that multiple cryptic species may be present among plants now called A. ruta-muraria. [5] Within the subclade, the A. ruta-muraria aggregate (including A. dolomiticum) is sister to the species formerly segregated in the genus Pleurosorus. [4]

Distribution and habitat

Asplenium ruta-muraria is native to Europe, East Asia, and eastern North America. [6] In North America, its range extends from western New England southwest along the Appalachian Mountains to Alabama and Tennessee. It is also found in the Ozarks and in southern Indiana and Ohio, with outlying occurrences in Michigan, Ontario, Quebec, and Clinton County, Iowa. [7]

In Europe, it commonly invades masonry and is a common species, while in the United States, it is more difficult to find, favouring pockets in very well-weathered and rather dry limestone outcrops.

<i>Asplenium flaccidum</i> Species of fern in the family Aspleniaceae

Asplenium flaccidum is a species of fern in the family Aspleniaceae. The plant common name is drooping spleenwort or weeping spleenwort, and the species name flaccidum derives from the Latin root meaning drooping.

<i>Asplenium montanum</i> Species of fern in the family Aspleniaceae

Asplenium montanum, commonly known as the mountain spleenwort, is a small fern endemic to the eastern United States. It is found primarily in the Appalachian Mountains from Vermont to Alabama, with a few isolated populations in the Ozarks and in the Ohio Valley. It grows in small crevices in sandstone cliffs with highly acid soil, where it is usually the only vascular plant occupying that ecological niche. It can be recognized by its tufts of dark blue-green, highly divided leaves. The species was first described in 1810 by the botanist Carl Ludwig Willdenow. No subspecies have been described, although a discolored and highly dissected form was reported from the Shawangunk Mountains in 1974. Asplenium montanum is a diploid member of the "Appalachian Asplenium complex," a group of spleenwort species and hybrids which have formed by reticulate evolution. Members of the complex descended from A. montanum are among the few other vascular plants that can tolerate its typical habitat.

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.
