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 ?  Bonnes fêtes à toutes et tous ! #botanique #botany #botanyquiz

Season’s greetings from our blog ▶️ 1url.cz/PJ6z5 Thank you to everyone who has read, shared, or contributed this year!🩷This illustration of buds on belowground storage organs is available with other materials here▶️ 1url.cz/FJ6z9 #GoBelowground #ExFuMo @ibotcz.bsky.social @czechacademy.bsky.social

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?

🌿My two (botanical)-cents🔍 In this forum paper, I reflect on the value of plant-identification expertise and offer a few ideas on how we can better highlight the role of botanists and their knowledge. onlinelibrary.wiley.com/doi/10.1111/...

Time to share! 🤍 Here are some of the subfossil wood samples that have been shipped all over Europe these days as counterparts for my recent crowdfunding campaign on Wemakeit! 🧊🔬 Thank you to all contributors for this incredible success! 🙏 Which one do you prefer? 🌲💍

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! #paleobotany

A year ago, Nora and Aly recorded an “Episode 0” to get a feel for the process and decide if they really wanted to make a podcast. Some plants are famously active in the winter. So famous, in fact, that they have become immediately recognizable symbols of Christmas and Winter Solstice holidays.

These strange trees are called 'pewen' or 'piñonero' in their native Chile, but when they reached England as an ornamental, barrister Charles Austin commented: "It would puzzle a monkey to climb that" So now, in English, they're called "monkey-puzzles." They get weirder up close...

Il est bien installé dans votre salon, décoré pour le réveillon… mais est-ce que votre sapin de Noël est vraiment un sapin ? 🎄 Épicéa, Douglas ou Nordmann, les noms vernaculaires n’aident pas forcément à identifier le genre auquel appartient un arbre.

More Jurassic cycad studies, looking at cones & stems/trunks primarily. There are some fossilized cycad cones (Androstrobus, Leptocycas, etc) and plenty of extant forms to draw inspiration/reference from. #paleobotany

These close-ups of mucilage-covered tentacle tips from the leaf of a carnivorous sundew plant (Drosera spatulata) definitely have a strong holiday vibe, so I am posting them just in time for the holidays. Happy Holidays. #microscopymonday #carnivorousplants

A chunk of Weald Clay from SE England, covered with fragments of ferns, conifers and other seed plants from 130 million years ago. Mesofossils may not look as appealing as large hand specimens, but can provide a better snapshot of vegetation. #FossilFriday ⚒🌏🌱🔬🌿🌲

Moss sporophytes

Finding good subjects to test a future macro lense for my phone next week... Golden eye lichen (Teloschistes chrysophthalmus) will be a good one! 💚

After illustrating quite a few ferns, I've now moved on to cycads! Here are some examples of Jurassic cycad morphology. With great thanks to @lepidodendron.bsky.social for his insightful blog post about cycads for #paleoart! #paleobotany #cycad

Where the wild #ferns grow 🌱🌿 Happy #FernFriday!

Alethopteris, a seed fern from the Carboniferous swamp forests 300 million years ago. This specimen is from Kansas. The fossils are on undulating bedding planes, and the specimen has beautiful brown tones (I'm used to darker, flatter UK coal measures material!) #FossilFriday #NotAFernFriday ⚒🌏🌱🧪🌿🔬

Teaching tropical #wood anatomy today. Look at this gorgeous #Andira (Fabaceae) and this nice aliform-confluent parenchyma pattern ! I only took the picture with my phone. It's all visible with a naked eye.

Last six years before glacier impact! 🧊😱 In the intimacy of this larch tree buried by Tschierva Glacier in 7623 BCE (i.e. ~9650 years ago)! 🌲💍 Note the significant growth reduction five years before the tree death! 🌊

Acer capillipes. trawling through the archives, I discover I have relatively few pictures of bark in winter. I'm not sure why, but this is the season to remedy this omission. 💚🌱
