British Pteridological Society

A great day doing a comprehensive Asplenium septentrionale count together with @NatResWales staff. Some positive site actions have already been done, and a good discussion on a management plan to look after this very special site. @FernBPS @fossilplants #FernFriday @cofnod

Up, up and....er gone: A great paper by @batkesp @SETarvin. Nowhere to escape – Diversity and community composition of ferns and lycophytes on the highest mountain in Honduras cambridge.org/core/journals/…

For a Filmy #FernFriday try tonight's BBC Gardeners' World (9:30pm BBC Two). Nick Bailey visits the Princess of Wales Conservatory @kewgardens where he celebrates their vast collection of #ferns. Also help with going #PeatFree

Looking forward to this talk about global patterns of #fern diversity featuring work done by @westo_fernnerd @frondley_fern & @MichaelSundue

Glad you enjoyed the Fernery, and hoped the students enjoyed it too.

Nice to meet friends from 'across the pond' this evening, with Julian Reed giving a great lecture on Athyrium cultivars, linking up @FernBPS and the Hardy Fern Foundation. #Athyrium #Ferns

A hurrah of Hart’s Tongue for #fernfriday @FernBPS

It's #FernFriday which is like #wildflowerhour but better 😉 Two common wood ferns, Dryopteris dilata and D. filix-mas among autumn leaf litter in Sefton Meadows @FernBPS

Want to cryopreserve #fern #spores or #pollen? Here you have our recently published protocols link.springer.com/protocol/10.10… @KewScience @wakehurst_kew @SocietyCryobiol @AmerFernSoc @FernBPS @Kew_MSBUK @kewgardens @GlasgowBotanic

Definitely one for the calendar, a talk by expert @westo_fernnerd on evolution and endemism, and even better featuring #Clubmoss #FernFriday @FernBPS (5pm GMT via YouTube)

For #fernfriday as I walked home in the High Weald this week: Hard-fern Struthiopteris spicant and Polypody Polypodium vulgare in a lane edge looking just fine. @FernBPS

16/10/20 Lancs - Not been on #twitter much the last week or so due to moving house, plus we have no internet or decent mobile reception at the new pad. We do however have lots more wildlife - here’s some #lichens and Polypody #ferns in our wall #fernfriday

Garretts also manufactured Watsonian Patent Fern Bricks. Patented by a doctor in 1859, these bricks were designed for planting ferns and mosses, to be hung on their own, built into walls, or even placed indoors on a table. 📸 Fernery, Newstead Abbey, Notts © Alan Murray-Rust 5/5

@FernBPS @BSBIbotany Recording plants in grounds of a garden centre here in Northants in the rain i crawled under a load of benches to find an alien fern species naturalised amongst lots of Harts tongue at base of outside of greenhouse wall. Im not sure of the species.

Common polypody (POLYPODIUM VULGARE) at kingscote church this afternoon @FernBPS @BSBIbotany

@AnarchyInTheWC Another method is physically spraying them off using just water from a hosepipe attachment or shower head at a moderately strong pressure to blast them off. All this methods need to be repeated often to reduce the aphid population.

@AnarchyInTheWC Hello! Good shots of your aphid population. Yes soapy water sprayed on works but can damage thinner fronds. A product called SB invigorator works well too.

Ostrich fern (Matteuccia struthiopteris) @BodnantGardenNT for #FernFriday @FernBPS @Love_plants

Great to see so much media coverage in past 24 hours about one tiny rare fern who travelled from tropical cloud-forest to Killarney, was found by @NimbosaEcology, IDd by Fred Rumsey @NHM_Botany, pub'd in #BritishandIrishBotany. All the links are here: bit.ly/34pWUN8
