A meme for #phylogenetics people.

Kumara, also recently segregated from Aloe, has just two species, the best known of which is K. plicatilis (1st 📷). The lesser-known K. haemanthifolia (2nd 📷, by Peter Thompson CCBYNC4) is a cracker & very worthy of cultivation. 😍

Continuamos la serie quincenal del Congreso de la SEBOT con Asturias. 𝘜𝘴𝘯𝘦𝘢 𝘧𝘭𝘰𝘳𝘪𝘥𝘢 es un conspicuo líquen de los húmedos bosques del norte peninsular. 🗓️¡Recuerda! Septiembre de 2025: congresosebot2025.com

Estas escenas de naranjas llenando las calles pueden resultar raras, pero no en Sevilla. Allí tendrá lugar el II Congreso de Botánica, donde uno de los principales árboles urbanos ed el naranjo amargo, Citrus × aurantium. ¿Quieres saber un poco más? 👇

The horizon from my office’s windows asked me to give another opportunity to my day 🥰

La Segunda Circular del Congreso Español de Botánica de 2025 ya está disponible 👇🏼 congresosebot2025.com/docs/circula... Tenéis información de cómo proponer simposios y talleres, abierto hasta el 28 de febrero. Os esperamos del 22 al 25 de Septiembre en Sevilla 🍊 ¡Pronto más info!

The Christmas Sedge announces that... It's time!!!!!

Some fabulous cheering Luronium natans on a dull December day. Got to love a bit of Floating Water-plantain 💚🌱

The spatial patterns of avian seed dispersal in fragmented anthropogenic landscapes are congruent with an ecological and evolutionary history with open and semi-open habitats created and maintained by extinct megaherbivores 🧑‍🎨: @claraprieto.com @journalofecology.bsky.social doi.org/10.1111/1365...

Behold! Gluteus minimus, an incertae sedis fossil whose name means "tiny butt" bizarrecreature.blogspot.com/2014/11/crea... Let your imagination gets you to... to the Devonian!

The generalistic house sparrow drinking nectar from Strelitzia nicholai in Torremolinos during Spring 2023. Is that how bird-plants interactions may start cementing @txaverius.bsky.social?

These are not flowers. I repeat: these are NOT flowers. What you see here is the Glass Flowers collection from the Harvard Museum of Natural History, in Cambridge, Massachusetts. Come with us to admire some of these stunning pieces! 👇🏼

#Drosera hyperostygma #Droseraceae! The Orange flowered Pygmy Sundews are a joy to see! These are common species in the Perth hills distinguished by their black stamen filaments and black egg shaped stigma for which they are named for! #WildOz

When you can't decide if you love dogs more than the herbarium.

When your toxic supervisor messed up the taxonomy and now you are in charge.

Cyperaceae are not known by their floral displays. Then one day you run into Cyperus proteus, a sedge that looks like a dandelion 😱 A striking case of mimicry to exploit insect-mediated pollination, where the anthela is modified into a colorful pseudanthium. www.inaturalist.org/observations...

This is how you imagine vouchers when you are from a place with a warm climate but head north in Winter to study a herbarium collection.

We spent this past week hunting more vouchers at the @nybg.bsky.social for the core imaging of iSedge @cetaf.bsky.social project. At this point the largest herbarium in the W Hemisphere helped us reach the incredible number of 1300 sedge species previously unavailable for www.cyperaceae.org! 😍

A drop of water balancing on top of hydrophobic trichomes of the invasive water fern Salvinia molesta. I split the leaf with a razor in order to get the full detail of the trichome structure.

When you work in a herbarium but you real passion is knitting. Seen at @nybg.bsky.social

I spent the last five summers sharing the infamous mediterranean heat with 15 species of thistles that flower at that somewhat absurd time of year, seeking to understand (something about) their thermal ecology. Here are the results. I think all my sweat was worth it. biorxiv.org/cgi/content/...

Sometimes when you revise herbaria you get to actually see a bit of the story behind the fieldwork (II). A voucher of Carex with a note from the colector at the end of the label 🥰😆 Seen at @nybg.bsky.social herbarium

For 1 week we have been at the Smithsonian NMNH in DC with iSedge project funded by @cetaf.bsky.social. We checked the entire Cyperaceae collection and set a loan of >700 species. That will boost our website www.cyperaceae.org with detailed pics of taxonomically relevant structures. Stay tuned!

This picture is the "Great Piece of Turft", 1503, by the German painter Dürer, preserved in the Albertina museum (Vienna). It is among the earliest pieces of art representing in detail grasses and other "non-flowering" plants. I always wondered if there is an equivalent pic depicting sedges

Salicaceae are famous for salicin, first isolated from Salix alba, which our bodies convert to salycilic acid, a painkiller. Other Salicaceae are toxic: Some Salix & Banara spp. have cyanogenic glycosides (viz. prunasin). 📷: Salix exigua (Matt Lavin CCBYSA2), a cyanogenic species. #botany 🌾🧪🌱

Mapania sylvatica (Cyperaceae), the sedge that wanted to be a Trillium.

True color images of the monochrome sedge -Lagenocarpus alboniger, Cyperaceae-. A plant that actually is black and white 🤯

Sometimes when you revise herbaria you get to actually see a bit of the story behind the fieldwork. A Machaerina (Cyperaceae) collected on 1915 near Itatiaia (Rio de Janeiro, Brazil), specimen from the Smithsonian's US collection @smithsonianmag.bsky.social

Scirpodendron ghaeri (Ghaer's clubrush-tree) is one of the largest Cyperaceae of the World. Native from S Asia, its inflorescences and nutlets are so massive for a sedge that, when it was originally described to science from a leafless sample, they named it Chionanthus ghaeri... in the Oleaceae!! 😱

The iSedge project (TETTRIs @cetaf.bsky.social) is visiting the herbarium of the Smithsonian Institution in Washington DC. Here we search for rare sedge species from all over the World to take high resolution pics of their tiny structures. Posting these on our website we will boost sedge taxonomy 😉

Una estratègia dels #briòfits per a multiplicar-se ràpidament és la reproducció vegetativa per mitjà de gemmes o propàguls. En algunes espècies, aquestes gemmes es troben en conceptacles en forma de copa (a l'esquerra, #Marchantia paleacea) o de mitja lluna (a la dreta, Lunularia cruciata).

A poster with some of the #birds that can be seen in Seville (Spain), created by @mascarell.bsky.social based on the species I suggested.

And it wasn't The Simpsons who predicted that, but @mfmazuecos.bsky.social who saw that coming years ago 😆: www.nature.com/articles/s41...

Negatively surprised to see that in my X I get less politics than here: years of blocking contents made my account purely professional. Today here I had to filter almost any content I saw: I was bombed by supposed progressists posts, many using harsh language. Is more polarization what we want here?

#Carnivorousplants fascinate people. So many different adaptations to catch #insects to increase the plants' nitrogen supply. Now maybe another - toxic nectar. www.science.org/content/arti...

This is not a drill, a mummified sabretooth cat has been published from the #Pleistocene permafrost of Russia. It's a Homotherium cub! The team (Lopatin et al.) reckon it's Homotherium latidens. It's too young to have enlarged upper canines. Paper is OA ... www.nature.com/articles/s41... cont...

Another nice past thread, that one about the Madroño (Arbutus unedo) and its relation with Madrid One of the nicest colors of Fall in Madrid is given by the ripe fruits of the Madroño -Arbutus unedo-, from the heath family (Ericaceae). Wanna know a bit more about the cultural roots of this plant? 👇

Getting started in Bluesky by reposting one of my first texts (Dec 2021): You probably wonder why there is a bunch of oranges next to a sidewalk. This isn't rare in Seville, Spain, where the Bitter Orange, Citrus × aurantium -also known as Seville Orange- is a street tree. Wanna know a bit more? 👇
