Lower latitude "shift to smaller plants such as palms and ferns. Leaf mass per area also increased as deciduous trees declined. Fossil soils indicate reduced soil organic carbon levels" ⚒️🧪

56 million years ago, the Earth suddenly heated up – and many plants stopped working properly
It could be a sign of what’s to come.

As botanists and Plant Architects in Montpellier 🌿, his vision of forests 🌳 profoundly shaped the way we think about and observe plants. A giant has passed, but his legacy will remain a major source of inspiration, worthy of our deepest admiration and gratitude.

Francis Hallé, botaniste et infatigable défenseur des arbres, est mort à l’âge de 87 ans
Le dendrologue, spécialiste des forêts tropicales et de l’architecture des arbres, avait réussi, grâce à ses talents de pédagogue et à ses dons de dessinateur, à capter l’attention et la sympathie du grand public. Il est mort le 31 décembre.

Prosopanache is the tropical American answer to Hydnora of Africa. The two genera are sisters, holoparasitic & lack chlorophyll. They appear above ground only as flowers. This is Prosopanche americana, parasitic on legumes. 📷: Agustín Zarco CCBY4 #Aristolochiaceae #Botany 🌾🧪🌱

I'm resharing in English the very sad news of the passing of French botanist Francis Hallé, specialist of tropical #forests and #tree architecture. You can find more about his life and career (and see some of his amazing drawings) here: www.foretprimaire-francishalle.org/en/who-is-fr...

We probably don't often plan to snack on tree bark, but we certainly do. Cinnamon is tree bark. There are five species of cinnamon from different geographical locations with distinctly different flavor profiles. This one is Cinnamomum verum, Sri Lankan cinnamon. Eat some bark today!

A sprinkling of leaves dropped from the host tree and gently landed on the wet ground below it. 260 million years later they find themselves encased in a block of stone in my study

Pour Noël, je me suis offert un objectif macro pour smartphone. Plus de botanique en 2026, voilà ma résolution de nouvel an. Qu'est-ce que vous en pensez ? Saurez-vous deviner de quoi il s'agit ?

I am interested in working with an artist on a graphic novel on soil and/ or global environmental change. The lab would have money to fund this.
Do you know of any graphic artists that would be interested?

A doubly old 'Christmas tree' this #FossilFriday! This was taken on Dec. 23 2010 during my 1st trip to Antarctica & shows a large fossil tree from the Triassic, 240 million years ago. The locality is high in the Transantarctic Mountains, above the Antarctic icesheet 🌿⛏️🏔️ Happy holidays!
