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.

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.
Exclusive: NSF this week began to search through billions of dollars of grants the agency has already awarded for anything touching on topics that President Donald Trump has criticized. And NSF has blocked grantees and trainees from accessing funds while the review is underway. scim.ag/3El0NZh

Curious how the phloem of this performs as artisanal paper.

#Amate (🇲🇽 indigenous #paper) art made by Yolanda Jiménez in San Pablito. Although amate traditionally was made from Ficus phloem, these have been depleted to supply the craft tourism industry. Artisans now use alternatives like tule (Typha domingensis, used below) for amate. #ethnobotany #botany

#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.

Some phloem fibers in the fibrarium (fiber herbarium) held in the @mobotgarden.bsky.social William L. Brown Center Biocultural Collection. These serve as known references to help identify unknown fibers in paper, textiles, & other ethnobotanical artifacts.
