#Isoetes
I studied quillworts in grad school at ODU. There is (or was) an ephemeral creek in VA that had a complete mat of Isoetes during winter. And there are some in GA (endangered) that grow in pools on granite outcrops. Cool plant.

I love looking at the designs of various lycopods' micro- & megaspores. The eFloras pg includes spore drawings.😍 Isoetes flaccida, the Florida quillwort, whose spore you can see at the link w/ others, is found mostly in clear ponds & slow-moving streams in GA & FL.

This new work investigates rhizotaxy on 3 rhizomorphic lycopsids including the unusual Mississippian-aged Oxroadia. We highlight the development of rhizotaxy on a juvenile Oxroadia as well as on the extant Isoetes. If you’re interested check out academic.oup.com/aob/advance-...

#roots. Fossilized ones. Isoetes
Huge congratulations @jeremywyman.bsky.social @instmolplantsci.bsky.social for publishing the results of your masters thesis @annbot.bsky.social
The work includes a new reconstruction of the Carboniferous isoetalean Oxroadia by the brilliant @palaeojules.bsky.social

Thanks @wickellomics.bsky.social for the brilliant @instmolplantsci.bsky.social seminar! Fascinating study of CAM evolution and I’m always excited for all things Isoetes.

A productive couple of hours scouring a shoreline in the rain and sifting through hundreds of broken specimens. Managed to find a handful of #Isoetes quills 😊 and a few invasive non-natives 🙁. #Quillwort

Delighted to see lush, green lawns of elegant Lake Quillwort (Isoetes lacustris), in the shallows of Ullswater at Howtown. New plant for me, it's to be found in oligotrophic lakes on both sides of Atlantic. Also a bit of Alternate Water-Milfoil & on the bank Yellow Loosestrife. #wildflowerhour 4/7

Less than a week to go until #Botany2025 - as you work on your schedules, check out some of the lab's talks!!

What if you take a weird ancient lycophyte, give it desert-plant-style photosynthesis, and throw it in a cold lake?
You get Isoëtes lacustris

Meet Melanie: she´s the good soul of the working group and our secret star. Nothing works without her & everything works with her. Our technician can do everything & saves the rest of us from putting our foot in our mouths. She is also into plant conservation: www.youtube.com/watch?v=-_0W...#isoetes

Inis bó finne is something else - great bird life, relatively invasive species free (which is like a yoga retreat for me 😅), good Guinness and was happy to see this Isoetes sp. today (no macrospores to be more sure on species)... Will start hunting it in home lakes as seo amach

How about the experiment? Successful? Did you follow some kind of germination protocol for Isoetes?

Quite right! What a magnificent #Isoetes novogranadensis H.P. Fuchs!

Since I've been working on some lycopsids recently, here's a diagram I made several years ago for a blog post I never got around to finishing.
So, here you go; enjoy some lycopodiophyte anatomy!
