"A genus comprising the butterworts (family Lentibulariaceae), which are small insectivorous bog plants with a slender flower stalk arising from a rosette of thick yellowish-green greasy leaves; (also pinguicula) a plant of this genus, a butterwort", Late 16th cent.; earliest use found in John Gerard (c1545–1612), herbalist. From post-classical Latin pinguicula, use as noun (short for planta pinguicula) of feminine of classical Latin pinguiculus rather fat (from pinguis fat + -culus), apparently after early modern German smalzchrawt, lit. ‘dripping weed, fat weed’, so named on account of its greasy leaves. Compare French grassette.[Pinguicula etymology, Pinguicula origin, 英语词源]
