Looks like Hayscented fern, Dennstaedtia punctilobula

A closeup of the rachis (stem) shows tiny hairs.
Also the frond is thrice-cut, once at right angle to the rachis (main stem), once at right angle to the costa (secondary stem), and once at right angle in the pinnule.

Can be weedy.

Asparagus fern perhaps?

Asparagus fern is not a fern.

Shocking.

It is a member of

...wait for it...

the asparagus family.

It has flowers. Ferns do not have flowers.

That's one of many reasons ferns are ferns, no flowers.

Fern enthusiast.

The fern grows next to a sign with its name. Clever fern.

Most ferns don't know their name. They're happy growing up without a name.

The fern looks like Dryopteris filix-mas, Male Fern.

Hart's Tongue. Asplenium scolopendruim. I see this plant posted frequently from UK posters.

An underlined quote in a book that reads as follows… “The biggest communication problem is we do not listen to understand. We listen to reply. – Stephen R. Covey” And I feel it is important to mention here that I was not the one that highlighted this quote (because I’m not a monster). Again, just to reiterate, I, Adam Sharp, do not, now or ever, go around highlighting passages in books like some kind of savage.

Today is World Listening Day so it's a good time to share this again...

Once-cut sensitive fern, Onocela sensibilis. Technically sensitive fern is between once-cut and twice-cut, called pinnatifid. The green fertile fronds are at the center of picture. They will get larger, turn brown, and winter over letting out the spores in the next spring.

Onoclea sensibilis is a once-cut fern. This is a twice-cut fern.

I don't know the ferns of Japan. The picture looks like Marsh fern (Thelypteris palustris). On iNaturalist.org Marsh fern has been identified in Japan.

Below is a picture of Sensitive Fern on left.

Osmundastrum cinnamomeum or Matteuccia struthiopteris (Ostrich fern).

Cinnamon fern fertile frond is cinnamon in color and comes out in mid to late spring.

Cinnamon fern has white tufts on the underside.

Another fern that split to make two blade tips.

Looks like Bracken

Royal Fern certainly likes to have its feet wet. A regal bog residence.

In middle ages ferns were thought to possess the magic of invisibility. There were elaborate steps to try and capture the magic. Even Shakespeare has references to fern's visibility.

Ferns did not have seeds, so how did they reproduce? Must be magic.

Right now, you're looking at the first known iNaturalist observation of the fern family Cystodiaceae! This species' scientific name is Cystodium sorbifolium.

It looks like river horsetail, Equisetum fluviatile.
The 'knobs' on the top are the source of spores in a structure called a strobolus (plural stroboli)

I did this before in German but I guess today is a good day to compile English resources on why AI isn‘t actually intelligent and also a real danger: 🧵

[ChatGPT] Etymology

Language of origin: Latin

Root word: indusium in Latin means a cloak, covering, or undergarment.

It comes from induere, meaning “to put on” or “to clothe.”

in- = “in, on” + duere (from induere) = “to put on clothing.”
In ferns, 'It clothes sori'

Looks like Lady fern, Athyrium filix-femina

gobotany.nativeplanttrust.org/species/athy...

A common fern.

It was a mystery until the late 1700s, early 1800s on how ferns reproduced.

There are references in Shakespeare's play to ferns imparting the spell of invisibility as the fern seed was no where to be seen, thus invisible.

For the fern enthusiast.

A two-panelled comic strip featuring a photo of a club moss in both. It looks like a small, almost miniature conifer tree. The first panel reads: Club mosses and not mosses. They are actually one of the earliest groups of vascular plants, appearing in the fossil record about 400 million years ago. During the Carboniferous Period (300-360 mya) they were as big as trees and grew over 100 feet tall. They dominated the great coal swamps at the time. The second panel reads: ... it's a fact they've never forgotten. A thought bubble from the moss reads (we will be giants again one day!)

I don't normally make comics, but this one has been in my head a long time. #MakeATerribleComicDay2025 #SciArt

A fine example of Sensitive fern, Onocela sensibilis.

Gets its common name from withering at the first cold snap.

Found where the ground is very moist. Can be weedy.

Yes, New York fern has the same talent of claiming the entire understory to itself.

A nice example of fern monoculture, probably Haysecented fern, Dennstaedtia punctilobula
