Eurinllys tonnog (Hypericum undulatum) yn sir Benfro / Wavy St. John’s-wort in Pembrokeshire.

Welsh Mudwort / Lleidlys Cymreig (Limosella australis) by the Afon Dysynni. The water boatman and small fish joined me in admiring this little plant.

Very different looking seeds between Drosera anglica (gwlithlys mawr / great sundew) and D intermedia (gwlithlys hirddail / oblong-leaved sundew). In the hybrid between D anglica and D rotundifolia the seed pods don’t really open and the seeds are just soft pale brown bits. #sundews #drosera

Huge congratulations to our lovely colleague James @bsbicountries.bsky.social on the publication today of his book, Endemic. More info here: www.bloomsbury.com/uk/endemic-9... Check out the thread below to find out about some of the endemic plants in the book inc Catacol Whitebeam & York Groundsel.

Fossil swamp-forest plants at Brymbo, Wrexham - where 300 million years ago giant lycopods (clubmosses) like Lepidodendron towered to over 120ft tall with massive horsetails like Calamites! Amazing to be able to see these at Stori Brymbo.

Great few days at the BSBI Wales Annual Summer meeting in Denbighshire this week / cawsom dri diwrnod gwych yng nghyfarfod haf blynyddol BSBI Cymru yn sir Ddinbych.

Here’s a tranquil little video of a cool mountain stream on Cadair Idris with Intermediate Water-Starwort (Callitriche brutia subsp. hamulata), with spanner-like tips to its narrow leaves.

Botanists in Wales re-find missing plants. BSBI press release: markavery.info/2025/07/09/b... What is gone for good? What remains to be rediscovered? @bsbibotany.bsky.social @bsbicymru.bsky.social @bsbiscotland.bsky.social @bsbiireland.bsky.social @natreswales.bsky.social @plantlifeuk.bsky.social

@britishspiders.bsky.social recently digitised 15k slide 📸 from arachnologists John & Frances Murphy. Spotted that one of their Snowdon Lily 📸 was exactly same clump/angle 54yrs later. Great to see this Mountain Spiderwort clump still thriving. @bsbibotany.bsky.social @natreswales.bsky.social

Blue anemone #GardenEscapes on the verge just outside the village. Not 100% sure yet if Anemone blanda or A apennina (opinions welcome!) - leaves are sparsely hairy underneath so leaning towards A apennina. #wildflowerhour

Rustyback fern / Duegredynen gefngoch (Asplenium ceterach) on limestone outcrops cleared of dense thorn, ash regen etc. by NRW & Llanymynech golf club. Nice to see, as no records here for 30+ years - would’ve been quite painful/scratchy to get to them in recent years!

This little Christmas cracker was found by the BSBI Meirionnydd Naturalists’ Group during their Christmas walk on Harlech dunes last Friday - Variegated Horsetail / Marchrawn Amrywiol (Equisetum variegatum)
