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?

A must-see if you visit Boston and something any botanist should have the privilege to see at least once in their lives 😉

Details even in parts where no one would expect an artist to pay attention to: see the realistic look of these roots!

It is the pieces representing the most familiar plants where one can see the incredible exatitude of these models.

The models are not simply an artistic demonstration. They have a great didactic value: the plants represented are anatomically accurate, and the models contain scale-magnifications of relevant organs, tissue and floral pieces.

The collection is a handmade work performed by the Blaschkas (father and son) during the late 19th and early 20th Century. www.hmnh.harvard.edu/glass-flowers The collection contains >700 plant models from all major taxonomic groups.

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! 👇🏼

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! 😍

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!

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 😉

This effect of madroños is long-known. Indeed the epithet unedo makes reference to this: unum edo, translated to English, eat only one! May have Linnaeus eaten quite a few to decide making this everlasting warning in the scientific name of the plant?

The Madroño appears in Madrid's coat of arms. It was added during the 13th Century to seal a dispute between the City Council and the Bishop. It ended with the transfer of the use of trees from the latter to the former. Being so symbolic, it is extensively used in Madrid gardens.
