This family of ferns is known as the "flowering ferns" because of the appearance of the ripe sporangia in four of its genera, including our genus of interest, Osmunda.

Ferns in this family tend to be much larger than others.

Named for Osmunder, the Saxon name for Thor. While this etymology is not entirely certain, it's unlikely that its association with the Slavic thunder god, Perun, is a coincidence. This fern has a strong association with thunder and lightning.

Modern flower language holds that the royal fern means "reverie" or "fascination," likely in reference to this fern's spiraling fiddleheads. It also means "dreams," possibly in reference to the fiddleheads or to the legendary wealth of the fern seed legend.

The sporangia, called "Perun's flowers" in Slavic mythology, were credited with the power to defeat demons, fulfill wishes, unlock secrets, and reveal to one the language of trees. This is very much the same story of the flowering fern.

In this tradition, one must draw a circle around the plant and withstand the harassment of spirits. The source relayed this, uncited. The takeaway here is that there are a lot of different beliefs about this fern-flower thing, and you can play fast and loose with it.

The young fiddleheads are edible when boiled and supposedly taste like asparagus.

  • The "royal" quality of the fern suggests it rules over the other ferns. A magically consequential interpretation would be that the royal fern countermands or suborn spells using other ferns as reagents, foci, or other tools/materials.
  • The sporangia is referred to as a "flower" while distinct from the legendary fern flower. Perhaps the legendary flower can be accessed in a diminished form via the royal fern's sporangia.
  • The secrecy quality is embedded in the spiral of the fiddlehead and the unfurling as the revelation of secrets. An unfurled fern may be a signifier of magical initiation.
  • Prominent thunder/lightning god associations. This is wide open to exploitation.
  • Look into St. Christopher.
  • As the "tree" fern, it has access to the liminal properties of trees. Consider this as a source of wand wood or as some sort of supplementary material.
  • Elemental Associations: [Thunder/Lightning], [Water]
  • Spirit Associations: [Gods], [Saints]

ADDER'S TONGUE

Order: Ophioglossales
Family: Ophioglossaceae

A small family of ferns typically characterized by a single fleshy leaf at a time.

Two genera draw our attention within this family: the adder's tongues (Ophioglossum) and the moonworts (Botrychium).

  • Europe, Western: Belgium, England, France (including Corsica), Ireland, Netherlands, Scotland

Biome: Temperate

There is only one species in this genus that we think is worth commenting on: Ophioglossum vulgatum.

Adder's tongue ferns are small plants roughly 10-20cm (sometimes 30cm) tall, formed of a central budding structure with radiating roots. This bulb produces a single fleshy leaf, named for the spore-bearing stalk that forks from the leaf stalk. The spore-bearing stalk resembles a snake's tongue.

The spore stalk is only sometimes present, and sometimes not even the leaf. Adder's tongues are known to go without any leaves at all for more than a year, living completely underground and relying on soil fungi to metabolize for them.

These plants tend to occur singly in pastures, rock crevices, and the like but are sometimes found in colonies of hundreds in sandy deserts.

These are rare in Europe.

We are not a medical blog; do not take health advice from us.

Wounds
Traditional European folk medicine calls for this plant's leaves and rhizomes to be used in a poultice for wounds, called the "Green Oil of Charity."

Hemorrhage
Adder's tongue tea was a European folk remedy thought to treat internal bleeding.

Nausea/Vomiting
Adder's tongue tea was a European folk remedy thought to prevent vomiting.

  • Obvious snake and lying associations. Exploit.
  • "Green Oil of Charity" is a curious name. Look into further and exploit.
  • "Adder's Spear" provides some possibilities for faeries, possibly with pixies using the leaves of Ophioglossum as militia armories.
  • Alternately, it might be used as a reagent for at-distance weapon recall.
  • Could be used as a reagent to curse someone with venom at-distance.

  • Oceania: Australia (New South Wales, Tasmania, Victoria), New Zealand (New Zealand South)

Biome: short grassland, woods, heaths, moors, etc.; wet and dry.

Moonworts are small ferns with fleshy roots, producing a single leaf and a spore stalk. A few species only occasionally emerge from the ground. Like many Ophioglossum, they can rely on fungi to metabolize for them for extended periods while staying underground.

Small plant up to 30cm tall. Splits into a sterile frond and fertile frond.

Grows in dry to moist short grassland, small woods, heaths, moors, etc. It is relatively rare in forests. Occasionally found in dune slacks.

In modern flower language, the moonwort means "forgetfulness." (This may actually be referring to Genus [Lunaria].)

This fern was thought to undo mechanisms. If one were to take a moonwort fern growing near a doorstep, one could insert it into the keyhole of the same door and thus freely open it. The same applied to fetters, regardless of mechanism. This property applied even to the shoes on a horse's feet, undoing the nails if the horse crossed a pasture where the moonwort grows (hence the name "unshoe-the-horse").

  • "Martagon" sounds like a particularly aggressive name for a faerie. Keep in mind that for a faerie warrior of some kind,
  • This subversion of mechanism also has a gremlin-like quality. Perhaps "Martagon" is a gremlin?
  • This mechanism could also be crossed with the flower language (likely appropriated later from [Lunaria]). The lock "forgets" to stay locked, the horseshoes "forget" to shoe, and so on.
  • The forked moonwort might be a good model for the tongue of a reptilian or draconic faerie or dragon. Finding a faerie dragon as a familiar in a fantasy story or RPG involves pulling the dragon up out of the ground by the tongue and having to discern it from surrounding moonworts. This would also give the familiar a distinct lunar aspect for magical or thematic reasons, possibly an oracular function as the moon's tongue (and, therefore, voice)!
  • "Key of the moon" can be exploited any number of ways, particularly in regards to dreams or passage into a lunar otherworld.
  • "Key of the moon" could also be ground and used in some way (possibly as a fumigant) to unlock the virtues of moon stone (either the orthoclase [feldspar] or the [gypsum], selenite).
  • Phases of the moon are baked into the plant's numerous lunar names.

Grape Fern (Botrychium matricariifolium)

Botrychium matricariifolium

Europe, Western

  • English: Grape Fern, Chamomile Grape Fern, Daisyleaf Grape Fern, Matricary Grape Fern
  • America, North: Canada (Labrador, Manitoba, New Brunswick, Newfoundland, Nova Scotia, Ontario, Prince Edward I., Québec), United States (Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Ohio, Pennsylvania, Rhode Island, South Dakota, Tennessee, Vermont, Virginia, West Virginia, Wisconsin)

  • Europe, Western: France

A small, fleshy fern up to 30cm tall. The lead blades may be up to 10cm long and 9cm wide. The fertile leaves are longer.

While native to Europe, these grape ferns are very rare.

  • Retained for names and distribution.
  • Applying the transitive property to the mystical fern flower and fern seed of legend, a grape fern might produce an elusive magical vine with magical grapes. The fern's rarity compounds this.
  • "Making fern wine" could describe a pointless and costly pursuit.

Prestigious Plants - Ferns 01 - Horsetail Ferns

Plant Indices

HORSETAIL FERN (Equisetum)

Order: Equisetales
Family: Equisetaceae

Equisetum telmateia (Equisetopsida) at Cambridge Botanic Garden.
Rror - Own work.

Europe, Central
  • German: Pferdeschwanz, Schachtelhalm, Zinnkraut
  • LINGUA IGNOTA: Franziz
Europe, Northern
  • Swedish: Skavgräs
Europe, Western
  • English: Horsetail, Bottlebrush, Candock, Joint Grass, Mare's Tail, Paddock-Pipes, Pewterwort, Puzzlegrass, Scouring Rush, Shave Grass, Tin-Herb
  • French: Prêle

An incredibly ancient lineage of fern. Branched members of the genus are referred to as "candock," and unbranched or sparsely-branched species are referred to as "scouring rush" for their use as an abrasive and superficial resemblance to rushes.

Bark Properties: Rich in silica.

Horsetail has a long history of being used as an abrasive, going back to at least ancient Sumeria. While not as effective an abrasive as modern sandpaper with its clear grades, when balled up, it doesn't get clogged with sanded material the way sandpaper does. It was used in the sanding of wood and the polishing of metals. It was particularly good at polishing tin, hence its German name, zinnkraut ("tin-herb").

We are not a medical blog; do not take health advice from us.

Despite being used medicinally in traditional medicine for millennia, there is little evidence that horsetail has natural medicinal properties.

Supposedly it was used as a stimulant, for weight control, skin and hair health, as well as bone health.

Contains the enzyme thiaminase, which breaks down thiamine (Vitamin B1), which can result in vitamin deficiency, making this herb toxic in large amounts, causing liver damage. Inadvisable as fodder for grazing animals for extended periods, and its effects on pregnant women has not been verified.

History of consumption, with fertile stems boiled like asparagus. Can be eaten cooked or, in the case of young shoots, eaten raw. As noted above, extended consumption is dangerous.

  • According to Andy Duling, the high silica content in the skin of horsetail can be used for sanding, but he had difficulty doing so, and was not impressed with the results. In contrast, Cappelle says it's quite useful, but notes that it should be cooked before drying for this purpose. Cappele balls it up, and this assists in preventing sawdust clogging.
  • This didn't just sand wood, but was apparently used in the polishing of metal, from kitchen pots to armor, according to a commenter on Cappelle's article.
  • Action associations: Scouring, Shaving, Puzzle-solving
  • Animal Associations: [Horse]
  • Metal Associations: [Pewter], [Tin].

  • Europe, Western: Belgium, France (including Corsica), Ireland, Netherlands, England, Scotland

Biome: Arctic and Temperate environments

Herbaceous perennial, with separate sterile and spore-producing stems. The sterile stems are green and photosynthesize, while the fertile stems are non-photosynthetic. Fertile stems grown in early spring, and sterile stems grow after the fertile stems wilted, and persist until autumn frost.

Horsetail rhizomes may penetrate the soil down to 1.8m (6ft) in depth. This species is incredibly difficult to get rid of in part for this reason, even resisting herbicides.

Apparently, this is the least toxic species of horsetail.

Sanding/Polishing
Used especially in the polishing of pewter, hence the name "pewterwort."

Music
Used to dress the wheels of hurdy-gurdies to remove resin build up.

Agriculture
Water-based extract of this plant is approved for use as a fungicide by the EU and post-Brexit UK. Also reduces the impact of excess moisture on other plants. High silica content reduces moisture impact.

We are not a medical blog; do not take health advice from us.

Despite being used medicinally in traditional medicine for millennia, there is little to no evidence that horsetail has real medicinal properties. Many of the following ideas come from traditional [Austrian folk medicine].

Supposedly horsetail ferns are:

  • Anti-inflammatory
  • Antioxidant
  • Antifungal (Confirmed)
  • Antimicrobial
  • Diuretic

In tea or topically in compress and back, it was and is used in the treatment of the following:

  • Chilblains
  • Gout
  • Kidney/UI issues
  • Locomotor issues
  • Skin disorders
  • Rheumatism
  • Wounds

Harvesting
For medicine, it is necessary to harvest the green stalks in spring or early summer while the leaves are "up." They should be bright green to be good for this purpose. During the summer it is also possible to harvest the tops. Boiling longer extracts more silica. 

Horsetail absorbs environmental toxins, so be careful where you collect your horsetail. Also mind that it is not marsh horsetail (Equisetum palustre), which is notably more toxic.

Anti-Inflammatory
This plant has many anti-inflammatory claims, which do not appear to have much scientific support. Still, assuming the claims are true, reduction in inflammation is supposed to promote stronger immune response against various pathogens. For this effect is best taken in tea or powdered supplement.

Bleeding/Wounds
This is a mild styptic, stopping bleeding. The barren stems and tops should be applied directly to the wound. Taken orally, this is thought to also treat excessive menstruation.

Joint Health
Supposedly the silica in the stalks of this plant is good for the joints and other connective tissue.

Bones
The high silica content in horsetail is supposed to promote strong bones, and is used  to treat osteoperosis when used consistently.

Teeth
The high silica content in horsetail is supposed to promote strong teeth. It can be made into a tooth powder that assists with cavities and enamel repair.

Skin and Hair
The high silica content in horsetail is supposed to treat skin issues. The silica is supposed to stimulate production of collagen to reduce the effects of aging by preventing fine lines and promoting healthy hair. It can be taken internally, externally as toner or wash, or added to a topical medium such as a cream, lotion, or salve.

Diuretic
Horsetail is said a gentle diuretic, which helps rid the body of excess fluids and salts. Treats kidney and UI issues, and prevents kidney stones from developing. Taken daily orally and with bath it can treat the symptoms of UTIs.

Antimicrobial
Horsetail is claimed has anti-inflammatory, antimicrobial, and antifungal properties (only the antifungal properties are confirmed). For this reason it treats external infections in warm compress or poultice, and can be used to treat fungal infections of the foot in a daily soak or to prevent such through soaks on alternating days.

Respiratory
Inhaling the steam of horsetail tea is supposed to reduce nasal and bronchial inflammation and congestion. Supposedly this also strengthens the immune system. Also treats sore throat in a saltwater gargle when combined with lemon juice.

Cognitive Function
The antioxidants in horsetail are supposed to prevent neural degeneration, preserving cognitive function. Apelian and Davis reference anecdotal evidence (their words) that it helped treat Alzheimer's in some patients.

Diabetes
The claim is that it helps to balance insulin levels in the body by lowering blood sugar. Apelian and Davis regard this as a short-term solution only.

While less toxic to humans than other horsetail species, it's still dangerous to livestock as a prolonged source of feed. Apelian and Davis also say beyond thiamine deficiency, it can cause potassium deficiency, lowered blood sugar, and kidney irritation. Not for pregnant women.

Further, it can synthesize nicotine under certain conditions, and overconsumption can lead to nicotine toxicity.

Rich in silicon, potassium, calcium, manganese, magnesium, phosphorus, fiber, Vitamins A, E, and C, and a host of other dietary chemicals. Buds are eaten as a vegetable in Korea and Japan. They are naturally bitter, do not eat raw. Change the water 2-3 times when boiling to reduce bitterness.

Rhizomes are edible, but hard to harvest in sufficient quantities. This makes them a starvation food.

  • The horsetail scours resin from hurdy-gurdies. Due to the potential symbolic density of the hurdy-gurdy (sacral origin, divine drone, cyclicality, bridge from sacral to profane, accumulation of gunk, etc.), much can be done with the horsetail in this regard.
  • Horsetail could be used in a regenerative capacity relative to the hurdy-gurdy, revitalizing the patient to restored faith or similar state by removing the accumulated malaise of repetition and habituation. Similarly, this could be used to break someone from a persistent hypnotic state. 
  • The above parallels its use as a sanding material and its supposed antioxidant properties vis-à-vis neurological health. Many of the purported medical benefits could easily be framed relative to the plant's scouring properties, if the characters perception of the world is pre-scientific.

Grows 30-100cm (occasionally 140cm) tall with dark green stems between 2-8mm in diameter. These stems are smooth with fine ridges. It is difficult to tell apart the fertile and photosynthetic stems. Stems pull apart readily at the joints.

Used as an abrasive for scouring, sanding, and filing, as other horsetails.

We are not a medical blog; do not take health advice from us.

Used in the ancient Mediterranean to stop bleeding, treat UI issues, ulcers, and tuberculosis.

The Chinese used it to treat superficial obstructions of the eye.

As generic.

Shoots harvested in the early spring can be eaten, but should not be consumed over extended periods.

According to Linnaeus, a fodder favored by reindeer. Used in Sweden to promote milk production in cows. Horses will not eat it. Waterfowl are known to eat the rootstock.

  • Chinese use of the obstructions of the eye could be translated magically as scouring or buffing away obstructions and blindspots. As such, horsetails could be used magically to disabuse people of their biases and ideological blinders (or to push situations that do the same).
