The genus #Viburnum can be hard to ID to species. This one, northern arrowwood (Viburnum recognitum), is distinguished by leaves that are nearly hairless, save for tufts in the vein axils on the abaxial side. #botany #adoxaceae

Universities like mine are limiting hiring, travel, and other spending using federal funds because of the fear of things like this. It's basically impossible to do science, whether NSF takes back funding or not.

One of the most disheartening experiences for me over the past 80 days has been the shattering of the illusion I harbored that academia (particularly wealthy private institutions filled with smart people) would uphold and fight for the ideas and values we cherish.

Important and also we need to start explaining to people that humans are just one species on the planet and research doesn’t have to be directly applicable them to be interesting, significant, or worth doing.

What the NSF is doing this week is damaging *generations* of scientific researchers and American investments in science. Billions of US tax payer dollars in investment, being thrown away, because of a fucking fishing expedition that is intended to terrorize and set the stage for a real witch hunt.

I'm an origamist, papermaker, ethnobotanist, and plant conservationist. The execution of my art is directly informed by my background in botany, and by the collaborations and partnerships I maintain with papermakers in Vietnam, Mexico, and Nepal.

#Paper I made from #Osage-orange (Maclura pomifera) phloem. Despite the intense yellow-orange color of the xylem, the dye is not conferred to the paper and the brown shade is likely due to the presence of a small amount of tannins. #papermaking #followingthepapertrail #ethnobotany #moraceae

generally no, but I've seen examples of barkcloth from Antiaris toxicaria phloem; the latex from this tree is also used for blowdarts, so I imagine there's a need to neutralize the poison before draping the tissue on your body...

James Ojascastro @manila-folder.bsky.social · 04/01/2025
Good paper plants tend to have long cellulosic fibers, regenerate readily, and are poisonous (toxicity means bugs won't eat resulting paper sheets). Best candidates are in the Moraceae and Thymelaeaceae, but bamboos are also used with regularity for lower-quality papers.

James Ojascastro @manila-folder.bsky.social · 04/01/2025
Some uses besides food are especially conservative. Most cultures that make paper or barkcloth use fewer than 5 species routinely as sources of fiber for such, and in many cases, just 1 sp. Fewer than 100 plants globally are known as raw materials in manual traditions of papermaking.
