" Not everyone embraced the [Linnaean] system warmly. Many were disturbed by its tendency toward indelicacy, which was slightly ironic as before Linnaeus the common names of many plants and animals had been heartily vulgar. The dandelion was long popularly known as the “pissabed” because of its supposed diuretic properties, and other names in everyday use included mare’s fart, naked ladies, twitch-ballock, hound’s piss, open arse, and bum-towel. One or two of these earthy appellations may unwittingly survive in English yet. The “maidenhair” in maidenhair moss, for instance, does not refer to the hair on the maiden’s head. "
