means A genus of flowering shrubs and small trees (including the smoke bush and smoke tree) known for their hazy, smoke-like plumes of feathery seed stalks.

from From Latin cotinus, the name the Romans used for a shrub many botanists link to the wild smoke tree (Cotinus coggygria) native to southern Europe — itself possibly traceable to an older term for a type of sumac-related plant. The genus name was carried into modern botanical Latin by Linnaeus, who used it to classify the smoke bushes; the hazy common name came later, inspired by the plant's otherworldly, smoke-like flower clusters rather than by the word's own ancient roots.
