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? 👇

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

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! 👇🏼

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.

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.

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.

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!
