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

It’s the big day! After four years of research, writing and editing (and procrastination, terror and imposter syndrome), Endemic has now been released to the world.

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.

Galeopsis speciosa (large flowered hemp nettle / y benboeth amryliw) in Montgomeryshire today, with its leaf beetle Chrysolina fastuosa.

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

For #wildflowerhour this week, they’re not #treeflowers but flowers that are nonetheless reliant on a tree! Toothwort / Deintlys (Lathraea squamaria), parasitic on the roots of the amazing old native black poplar in the car park by the River Severn in Newtown, Powys.

Two cracking crucifers from different ends of Wales this week - Yellow whitlowgrass / Llysiau‘r-bystwn melyn (Draba aizoides) going to seed on Gower yesterday, and Alpine pennycress / Codywasg y mwynfeydd (Noccaea caerulescens) flowering in Gwydir Forest earlier in the week.

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
