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. 😍

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? 👇

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...

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! 😍

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/...

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 🌾🧪🌱

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!! 😱

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).

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?

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? 👇
