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.

#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.
