Hordeum is a genus of annual and perennial plants in the grass family. They are native throughout the temperate regions of Africa, Eurasia, and the Americas.
Asplenium is a genus of about 700 species of ferns, often treated as the only genus in the family Aspleniaceae, though other authors consider Hymenasplenium separate, based on molecular phylogenetic analysis of DNA sequences, a different chromosome count, and structural differences in the rhizomes. The type species for the genus is Asplenium marinum.
Asplenium platyneuron, commonly known as ebony spleenwort or brownstem spleenwort, is a fern native to North America east of the Rocky Mountains. It takes its common name from its dark, reddish-brown, glossy stipe and rachis, which support a once-divided, pinnate leaf. The fertile fronds, which die off in the winter, are darker green and stand upright, while the sterile fronds are evergreen and lie flat on the ground. An auricle at the base of each pinna points towards the tip of the frond. The dimorphic fronds and alternate, rather than opposite, pinnae distinguish it from the similar black-stemmed spleenwort.
Asplenium nidus is an epiphytic species of fern in the family Aspleniaceae, native to tropical southeastern Asia, eastern Australia, Hawaii, Polynesia, Christmas Island, India, and eastern Africa. It is known by the common names bird's-nest fern or simply nest fern.
Species Plantarum is a book by Carl Linnaeus, originally published in 1753, which lists every species of plant known at the time, classified into genera. It is the first work to consistently apply binomial names and was the starting point for the naming of plants.
Asplenium scolopendrium, commonly known as the hart's-tongue fern, is an evergreen fern in the genus Asplenium native to the Northern Hemisphere.
Asplenium serratum, the bird's nest spleenwort, wild birdnest fern, or New World birdnest fern, is a fern of the New World/Americas.
Asplenium rhizophyllum, the (American) walking fern, is a frequently-occurring fern native to North America. It is a close relative of Asplenium ruprechtii which is found in East Asia and also goes by the common name of "walking fern".
Asplenium ceterach is a fern species commonly known as rustyback.
Asplenium trichomanes, the maidenhair spleenwort, is a small fern in the spleenwort genus Asplenium. It is a widespread and common species, occurring almost worldwide in a variety of rocky habitats. It is a variable fern with several subspecies.
Asplenium septentrionale is a species of fern known by the common names northern spleenwort and forked spleenwort. It is native to Europe, Asia and western North America, where it grows on rocks. Its long, slender leaves give it a distinctive appearance. Three subspecies exist, corresponding to a tetraploid and a diploid cytotype and their triploid hybrid.
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.
Asplenium ruta-muraria is a species of fern commonly known as wall-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.
Sea spleenwort may refer to:
Asplenium listeri, commonly known as the Christmas Island spleenwort, is a species of fern in the family Aspleniaceae. It is endemic to Christmas Island, an Australian territory in the northeastern Indian Ocean. Its specific epithet honours British zoologist and plant collector Joseph Jackson Lister, who visited the island on HMS Egeria in 1887 and was the first to collect a specimen.
Asplenium viride is a species of fern known as the green spleenwort because of its green stipes and rachides. This feature easily distinguishes it from the very similar-looking maidenhair spleenwort, Asplenium trichomanes.
Asplenium adiantum-nigrum is a common species of fern known by the common name black spleenwort. It is found mostly in Africa, Europe, and Eurasia, but is also native to a few locales in Mexico and the United States.
Asplenium onopteris, known as the Irish spleenwort or western black spleenwort is a species of fern found mostly throughout the Mediterranean Basin but also around the Eastern Atlantic.
Clematis viorna, commonly known as vasevine or leatherflower, is a flowering vine native to the southeastern United States. It grows in wooded habitats and bears purple flowers in spring and summer.
Asplenium hemionitis is a species of fern native to Macaronesia, Northwest Africa and mainland Portugal. It inhabits humid woods and other shady areas, sometimes in uncovered slopes subject to high ocean humidity.
