Tree rings are amazing! 🌲💍🥰

Here is a 600 yr-old Siberian pine cross section showing no less that 7 scars on the tree side facing the rock cliff upstream! 🔥

All the scars are dated to the year (or season) and are used to build chronicles of different hillslope processes! 📅

Paleo folks: Please recommend researchers (incl yourselves) interested in phylogenetic reconstruction in deep time, molecular clocks (discord w/ fossil clocks), foundational/methodological issues in phylo/paleo-reconstruction & who'd be interested in hanging w/ historians & philosophers of science ⚒️

Kunming #BotanicalGarden (CN) is absolutely amazing!✨
Beyond safeguarding thousands of species through living collections, it's actively involved in the regeneration of extremely #rareplants by eventually climbing 80-meter #trees to collect #seeds and saving species from #extinction💚

Congratulations to @jeremywyman.bsky.social et al 2025 for the publication of their Oxroadia paper! And thanks for bringing me onboard to do some restorations of this relative of Lepidodendron and Isoëtes from the Carboniferous of Scotland.

What’s going on at @umramap.bsky.social ??

We're startin a new exp on Med temporary lagoon ecology.

The aim: understanding how plant communities differ from what’s in the seed bank (and why..)

Deep in the Sumatran jungle today we found the extraordinary flowers of Rhizanthes pushing their fangs through the forest floor. A sap-sucking, leafless parasite, this is one of the world's weirdest plants.

The conifer _Podocarpoxylon mazzonii_ from the uppermost Cretaceous of Patagonia, in three sections: radial longitudinal, tangential longitudinal, and transverse.

Yes, it has multiseriate (up to pentaseriate) rays.

Clusia major (Trinidad & Lesser Antilles) has dangling aerial roots that eventually touch the earth—not surprising for a hemiepiphyte that starts life in a tree (or, as here, on a cliff). What is surprising is that sometimes shoots grow from the roots. #Clusiaceae #TropicalBotany #Botany 🌾🧪🌱
