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

Perhaps we should start doing this with plants too ;-) cuddy would be nice name for cudweeds, knappy for knapweed, or using scientific names we could have fun with Hypy for St John’s worts, Stelly for Stellaria! Sorry, I’ll stop now.

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.

Yep. Looks like it’s been recorded there before. At Ryedale folk museum?

That’s nice. Whereabouts was that on the canal?

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.

What is gone for good? What remains to be rediscovered?

@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

Two Welsh endemic trees on the limestone in Breconshire - Welsh whitebeam (Sobus cambrensis) and lesser whitebeam (Sorbus minima) - particularly smitten with minima. #Sorbus #whitebeams

True service tree / Cerddinen Morgannwg - the service tree of Glamorgan (Sorbus domestica) on the breezy cliff top above the Bristol Channel / Môr Hafren. #sorbusdomestica #highupplants

Super to find #HighUpPlants of Salix herbacea (Dwarf Willow) on Friday - a first record for 50 years on this hill, and hectad #NatureNetworks #RhwydweithiauNatur #wildflowerhour

Went to search for a little white flower on the Llŷn today - Didn’t find it, but saw other white-flowered beauties! Incl. Pale dog-violet (Viola lactea), white ramping fumitory (Fumaria capreolata), and field mouse-ear (Cerastium arvense). #NatureNetworks #RhwydweithiauNatur

Hutchinsia / beryn y graig (Hornungia petraea) in the dunes at Whiteford Burrows NNR, Gower v.c.41. #cabbagefamily #wildflowerhour

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.

Stunning #woodlandplants from the limestone woods in Denbighshire - yellow star-of-Bethlehem (Gagea lutea), wild daffodil (Narcissus pseudonarcissus) and early dog-violet (Viola reichenbachiana) #wildflowerhour

Two black-blotchy-leaved #woodlandplants together, Arum maculatum (lords-and-ladies etc) & Orchis mascula (early-purple orchids). #wildflowerhour

Mwsglys heddiw / Moschatel today #Adoxa moschatellina #gwanwyn

That’s interesting - I didn’t know the Greek Anemos and wind link. Blodyn y Gwynt is the standard Welsh name, but like many plants there are lots of other names, and some have no association with wind e.g Bara Caws, Brithlys, Brithogen y Goedwig.

#WoodAnemone this week - its Welsh name is Blodyn y Gwynt (the flower of the wind), but another old local name is Bara Caws (cheese bread!) #wildflowerhour

Yn galw ar fotanegwyr sy'n siarad cymraeg!
