There's #FernFriday and of course #ferns

They are so cool

I found this little fern in Planten un Blomen, Hamburg. I'm not sure if it's Asplenium bulbiferum or A. daucifolium. Both ferns look very similar.

Some details of a frond. The sori and the rachis of a lady fern (Athyrium filix-femina).

Liuska- ja tummaraunioinen (Asplenium septentrionale, A. trichomanes), koska miksipä ei.

Näiden etsintä voi sitten aiheuttaa voimakasta a) turhautumista (kasvupaikat harvassa ja monia vanhoista esiintymistä ei enää löydy), b) riippuvuutta.

A wall-rue (Asplenium ruta-muraria) grows in a joint of a building-wall in Wetter, Germany. #ferns #FernFriday

Hard shield fern (Polystichum aculeatum) and maidenhair spleenwort (Asplenium trichomanes) near a ruin in Volmarstein, Germany.

A favorite in our NZ fern book, because of the unique shape of its foliage, is Trichomanes reniforme (=Cardiomanes reniforme; the kidney fern) in the Hymenophyllaceae. The fertile fronds have numerous sori along the margin. #FernFriday

Another 𝘗𝘵𝘦𝘳𝘪𝘴 species in our collection of NZ #ferns is labeled as 𝘗𝘵𝘦𝘳𝘪𝘴 (𝘭𝘪𝘵𝘰𝘣𝘳𝘰𝘤𝘩𝘪𝘢) 𝘮𝘢𝘤𝘪𝘵𝘦𝘯𝘵𝘢. This may be a misspelling of 𝘗. 𝘮𝘢𝘤𝘪𝘭𝘦𝘯𝘵𝘢, which is endemic species to NZ. 𝘗𝘵𝘦𝘳𝘪𝘴 𝘮𝘢𝘤𝘪𝘭𝘦𝘯𝘵𝘢 (sweet fern) is described as having “sori in the notches between the segments, not nearly reaching their tips” (Crookes, 1963), which is displayed nicely in this specimen. Just because it’s cool, here's also a high magnification of the sporangia. You can even see a stoma & some of the spores! #fernfriday

A truly gorgeous item in our collection is this 📗, New Zealand Ferns. Prepared and mounted by T. Cranwell in Parnell, NZ, it features a green leather spine and carved wooden panels for the front & back covers. This was gifted to the University of Tennessee Dept. of #Botany (now EEB) by Irvin Saxton in April 1945. It had been a gift to his grandfather from his grandfather’s brother (so Irvin's great uncle) in 1870. #FernFriday

#FernFriday one of my fave pics I've taken, May 9, 2020, Syracuse, NY

No fossil today but the fern in my office that I use to confuse people working on fossil leaves 😇🌿
Happy #FernFriday!

Ostrich fern (post fiddlehead) at Fairbank Woods, Oil Springs ON, May 2019 - for #FernFriday, Daily #PhotoTheme #Photography #POTD

#FernFriday: There are a few epiphytes on this tree trunk in #Ngeremlengui #Palau but the most abundant plants you can see are the one-cell thick (except for the vascular tissue) fronds of Crepidomanes (Hymenophyllaceae)

For #FernFriday here is Elaphoglossum peltatum growing around the base of an Alsophila tree fern in the forest on Cerro Punta in Puerto Rico. This is from a field site for an Alsophila hybrid zone that Dave Conant and students studied. #ferns #PuertoRico #botany

For #FernFriday here is Astrolepis sinuata from Cave Creek Canyon in the Chiricahua Mountains.
