Derivation of the botanical name:
Urtica, uro, I burn, alluding to the nettle's sting; stinging nettle. Their capability to sting makes them useful for metaphors.
dodartii, named for Denis Dodart (1634 – 1707), a French physician, naturalist and botanist.
pilulifera, pilula, a little ball, a pill; fero, to bear, carry, bring; with little balls.
In the Bible three different Hebrew names are quoted: Sirpad (סרפד)- in Isaiah 55:13; Seravim (סרבים)- in Ezekiel 2:6; Harul (הרול)-Zephaniah 2:9. They are synonyms, the roots s-r-f and h-a-r both meaning 'scorching' or 'burning'.
