A catkin, which is a fuzzy flower cluster that hangs from trees like birch and willow.
From Latin 'amentum' (strap or thong), named because catkins resemble hanging loops or straps of fabric on branches.
Catkins look like fuzzy little straps dangling from branches in spring—so botanists literally named them after the Latin word for strap because of their shape, turning a weapon part into a plant term.
