Pleased to find a new site for alternate-leaved golden-saxifrage, in Glens of Foudland, North Aberdeenshire. Nearby, striking autumn colours of sheep's sorrel and either pale lady's-mantle (BSBI Handbook) or intermediate lady's-mantle (BSBI DDb) as vernacular names for Alchemilla xanthchlora.

Got it! Dozens of small plants of Chenopodium vulvaria on damp sandy mud and shingle around a shallow depression at Landguard Common. Thanks to @bramblebotanist.bsky.social for directions. Now on to see the Cynosurus echinatus I last found here in 1998...

Sea Arrowgrass Triglochin maritima. You have to look very close to see that it's actually flowering! Chidham Point, West Sussex. @bsbibotany.bsky.social

A trip to Suffolk wouldn't have been complete without calling in to see the hog's fennel Peucedanum officinale beside the footpath skirting Woodsend Marshes at Southwold

Grass-of-Parnassus (Parnassia palustris) at St. John's Wood, Co. Roscommon yesterday. @bsbiireland.bsky.social

Many (and belated!) Thanks to the #NorfolkFloraGroup and @jo-the-botanist.bsky.social for a great day in the field! Looking forward to the next field meeting (and more surveying!) 🥰🌱🌿

Hope I'm not boring everyone with another Atriplex x gustafssoniana (Spear Lvd x Long-stalked Orache) hybrid swarm at Gorrangorras Creek Cornwall today. See ALT.

A fight going on in the rice fields of the Tagus Estuary near Lisbon. Azolla filiculoides and Lemna gibba fighting it out for supremacy. The Azolla fronds arching upwards to cover the Lemna, and the Lemna becoming as gibbous as possible to prevent this. They are seemingly resorting to fisticuffs.

Slender Hare's-ear Bupleurum tenuissimum on the coast between Prinsted and Nutbourne, West Sussex today. Locally very common, preferring the edges of compacted gravel paths behind the sea wall. @bsbibotany.bsky.social

Revisited an odd horsetail at Den of Maidencraig LNR, Aberdeen, which I think is shore horsetail, the hybrid of water and common horsetails. Like a long-branched common horsetail but with stems smoother, compressible due to a large central hollow and protruding cortex when pulled apart lengthways.

Buckwheat is flowering well at Dublin Docklands, and has Flax for company now. #urbanbotany #wildflowerhour @bsbibotany.bsky.social

Finally found deadly nightshade in the wild. Lovely glossy berries On a verge in Oxford. @bsbibotany.bsky.social #wildflowerhour

Stepped into neighbouring West Sussex on a beautiful afternoon. Sea-heath Frankenia laevis was surprisingly common on a stretch of crumbling concrete near Chidham. Even some flowers! Not a common plant in Hampshire, despite lots of suitable habitat. @bsbibotany.bsky.social

Led by 'Orchid Summer' author @dunnjons.bsky.social & local Sicilian naturalist legend Andrea Corso, and staying in glorious rural Sicilian agriturismos with amazing food and architecture, this is a feast for the senses. And guarantees a donation to support the work of @bsbibotany.bsky.social. (2/2)

Good morning and welcome to a new week! Our featured tour this week is a special orchid quest - Late Spring Orchids of Sicily offers the opportunity to see the uniquely yellow, late-flowering Ophrys lacaitae, and some other special bee orchids. (1/2) mariposanature.com/tours/botani...

The Lundy Cabbage, Coincya wrightii, is one of our most special endemic plants. Discovered surprisingly late, 1930s, it is only known from about 3km of the east coast of Lundy, off the coast of Devon, where it mostly grows on steep, inaccessible cliffs.

Hawkweeds (Hieracium spp.) are very tricky! There's a helpful #BSBIHandbook to Hawkweeds of SE England, doesn't inc Suffolk but might be useful, is available as an eBook so you can have it on your phone: bsbi.org/publications... Cost £4 if you take part in our survey: docs.google.com/forms/d/e/1F...

Reminder that if you want to apply to become Manager of our @daera-ni.gov.uk -funded Botanical Skills Northern Ireland Project, you need to get that application in by midnight!

The archaeophyte, Pale Toadflax (Linaria repens) at @rspbcymru.bsky.social Ynys-hir. Often associated with railways as indeed it is here. #WildflowerHour plantatlas2020.org/atlas/2cd4p9...

A wonderful #WildFlowerHour as summer draws to an end, nights get cooler & tomorrow is the Equinox. Wonder what will still be in flower next week? Let's meet up next Sunday to compare notes! @wildflowerhour.bsky.social

Plenty of tiny, beautiful, Eyebright flowers in the wild quarries on Portland. Not sure of species - my Wildflower ID book quickly made me realise these were going to be tricky, and that feeling was compounded by one of the Eyebright having the scientific name of Euphrasia confusa!! #wildflowerhour

Clustered Bellflower, now in a range of colours #wildflowerhour

#WildflowerHour Late flowering Red Campion on this mellow autumn equinox (ish) day

A late flowering Dyer's Greenweed taking advantage of the recent rains #WildflowerHour

#Wildflowerhour from #Lancashire this week, yesterday deluge meant slim pickings! Enjoy acorns, spindle fruit, ivy flowers and hawthorn, and whilst invasive balsam plays a part in helping #bees this time of year. If only it could be contained! @wildflowerhour.bsky.social @bsbibotany.bsky.social

Wrapped up a survey day with this wildflower bouquet of Goldenrod and Zigzag Clover — best kind of field bonus! #WildflowerHour

#WildflowerHour Lots of chicory still in flower. Gloucestershire.

Last Shropshire Botanical Society field trip of 2025 on Catherton Common in the sun. Well attended, some fine plants recorded in the mires, we ended with the tiny and unassuming Chaffweed (Lysimachia minima) by the roadside at one of its rather few sites in the county. #wildflowerhour
