Woodsia ilvensis, commonly known as oblong woodsia, [4] is a fern found in North America and northern Eurasia. Also known as rusty woodsia or rusty cliff fern, it is typically found on sunny, exposed cliffs and rocky slopes and on thin, dry, acidic soils. [3] [5] [6] [7]
The leaves are typically 6 inches long and 1 inch wide, with stiff, erected pointed tips and cut into 12 nearly opposite stemless leaflets. The underside of the leaves are covered in white woolly fibres, which later turn rusty brown. [8]
The plant was first identified as a separate species from specimens collected in Scotland in Bolton's 1785 publication Filices Britannica. Bolton distinguished between Acrostichum ilvense and Acrostichum alpina, now Woodsia ilvensis and Woodsia alpina respectively, which had previously been conflated. [7] The genus Woodsia was established in 1810 by Robert Brown, who named it after the English botanist Joseph Woods. [6] [7] "Ilvensis" is the genitive form of the Latin name for the island of Elba. [5]
Woodsia ilvensis is one of the parents of the hybrid × Woodsimatium abbeae, the other being Physematium scopulinum . [9]
Its distribution is circumpolar. It is most abundant in Scandinavia, the Ural and Altai mountains and the eastern United States. [7] It is also found in Japan, [5] Alaska, Canada, coastal Greenland and various European locations including the Alps.
It is considered "Threatened" or "Endangered" in the states of Illinois, Iowa, and Maryland and "Presumed Extirpated" in Ohio. [2] [3] Also found in West Virginia and North Carolina, it is the most common Woodsia species in the US. [6]
Its UK distribution is confined to Angus and the Moffat Hills in Scotland, north Wales and Teesdale and the Lake District in England. [7] There are fewer than 90 wild clumps in the whole of the UK, where it is on the edge of its natural range and is considered to be "Endangered". [7] [10] For this reason it became a protected species in the UK in 1975 under the Conservation of Wild Creatures and Wild Plants Act. [11]
Oblong woodsia came under severe threat from Victorian fern collectors in the mid 19th century in Scotland, especially in the Moffat Hills. These hills once had the most extensive UK populations of the species but there now remain only a few small colonies whose future is under threat. This period of collecting became known as pteridomania (or "fern-fever"). The Royal Botanic Garden Edinburgh plan to use cultivated specimens and a spore bank to restore depleted wild populations.

The Royal Botanic Garden Edinburgh (RBGE) is a scientific centre for the study of plants, their diversity and conservation, as well as a popular tourist attraction. Founded in 1670 as a physic garden to grow medicinal plants, today it occupies four sites across Scotland—Edinburgh, Dawyck, Logan and Benmore—each with its own specialist collection. The RBGE's living collection consists of more than 13,302 plant species, whilst the herbarium contains in excess of 3 million preserved specimens.

Gagea serotina, synonym Lloydia serotina, is an Arctic–alpine flowering plant of the lily family. It is widespread across the mountainous parts of western North America, from Alaska to New Mexico, and in Europe is found in the Alps, the Carpathians and the mountains of Bulgaria, as well as in Great Britain. It is also native to much of Central Asia, Siberia, China, Nepal, Mongolia, Korea and Japan.
Grey Mare's Tail is a 60-metre (200 ft) hanging valley waterfall near to Moffat in southern Scotland. The fall is produced by the Tail Burn flowing from Loch Skeen cascading into the Moffat Water in the lower valley below.
Dianthus gratianopolitanus, commonly known as the Cheddar pink or clove pink, is a species of plant in the family Caryophyllaceae. It is a herbaceous perennial, hardy to zones 4–8. It grows to a height of 0.5 to 1 feet, blooming from May to June. Flowers are fragrant and rose pink. Grows best in full sun, and has medium water requirements. Overwatering or poor drainage leads to crown rot, and plants do not tolerate wet winter soil conditions.
Orchis simia, commonly known as the monkey orchid, is a greyish pink to reddish species of the genus Orchis. It gets its common name from its lobed lip which mimics the general shape of a monkey's body.
Saxifraga paniculata is an alpine species of flowering plant in the saxifrage family, with native distribution in the temperate northern hemisphere. Common names include alpine saxifrage, encrusted saxifrage, lifelong saxifrage, lime-encrusted saxifrage, livelong saxifrage, white mountain saxifrage, and silver saxifrage.
Cicerbita alpina, commonly known as the alpine sow-thistle or alpine blue-sow-thistle is a perennial herbaceous species of plant sometimes placed in the genus Cicerbita of the family Asteraceae, and sometimes placed in the genus Lactuca as Lactuca alpina. It is native to upland and mountainous parts of Europe.
Woodsia is a genus of ferns in the family Woodsiaceae. Species of Woodsia are commonly known as cliff ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it was the only genus in the family Woodsiaceae. In 2020, Physematium was split off from Woodsia on the basis of molecular phylogenetic evidence. As of June 2023, Plants of the World Online continued to treat Physematium as a synonym of Woodsia.
Woodsiaceae is a family of ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is placed in the suborder Aspleniineae. The family can also be treated as the subfamily Woodsioideae of a very broadly defined family Aspleniaceae sensu lato. In PPG I, the family contained only one genus, Woodsia. In 2020, Physematium was split off from Woodsia on the basis of molecular phylogenetic evidence. As of June 2023, Plants of the World Online continued to treat Physematium as a synonym of Woodsia.
The flora of Scotland is an assemblage of native plant species including over 1,600 vascular plants, more than 1,500 lichens and nearly 1,000 bryophytes. The total number of vascular species is low by world standards but lichens and bryophytes are abundant and the latter form a population of global importance. Various populations of rare fern exist, although the impact of 19th-century collectors threatened the existence of several species. The flora is generally typical of the north-west European part of the Palearctic realm and prominent features of the Scottish flora include boreal Caledonian forest, heather moorland and coastal machair. In addition to the native species of vascular plants there are numerous non-native introductions, now believed to make up some 43% of the species in the country.
Woodsia alpina, commonly known as alpine woodsia, is a fern found in northern latitudes in North America and Eurasia. Also known as northern woodsia or alpine cliff fern, it is typically found in crevices, scree slopes and cliffs containing slate and calcareous rocks, especially limestone.
Vandenboschia speciosa, synonym Trichomanes speciosum, commonly known as the Killarney fern, is a species of fern found widely in Western Europe. It is most abundant in Ireland, Great Britain, Brittany, Galicia, Canary Islands, Madeira and the Azores, but is also found in other locations including France, Spain, Portugal and Italy. It is a relict endemic European species with a disjunct distribution, having had a much wider distribution before the climate changes of the Tertiary and Quaternary periods.
Pteridomania or fern fever was a Victorian craze for ferns. Decorative arts of the period presented the fern motif in pottery, glass, metal, textiles, wood, printed paper, and sculpture, with ferns "appearing on everything from christening presents to gravestones and memorials".}
Corrie Fee is a glacier-carved corrie situated at the head of Glen Clova in the Angus Glens of Scotland. It forms part of Corrie Fee National Nature Reserve (NNR), which is managed by NatureScot and lies within the Cairngorms National Park. The adjoining Corrie Sharroch and the slopes of Craig Rennet are also included in the NNR.
Austroblechnum penna-marina, synonym Blechnum penna-marina, known as Antarctic hard-fern, Little Hard Fern, Alpine Hard Fern, alpine water fern and pinque, is a species of fern in the family Blechnaceae. It is a widely distributed fern species in the southern hemisphere, with a natural range including New Zealand, Australia, and South America.
Sabulina stricta is a species of flowering plant in the family Caryophyllaceae known by the common names bog stitchwort, Teesdale sandwort and rock sandwort. It has a circumboreal distribution, occurring throughout much of the northernmost Northern Hemisphere from the lower Arctic into the alpine climates of mountainous areas in temperate Eurasia and North America. It grows in several types of habitat, including meadows, marshes, heath, beaches and bars, and arctic and alpine tundra.
James Bolton was an English naturalist, botanist, mycologist, and illustrator.
Bartsia alpina is a species of perennial flowering plant, known by the common name alpine bartsia or velvetbells. It is found in the mountainous regions of Europe and also occurs in Iceland, Greenland and north-eastern Canada.
Dryopteris fragrans, commonly known as the fragrant woodfern, a circumboreal fern, is the smallest of the Dryopteris species. It can resemble Woodsia ilvensis in the wild, with which it shares the same habitat of rocky areas, shady cliffs, screes, and limestone talus. It typically will not reach more than 25 cm in height, and accumulates dead fronds around its base.
