Obs. [App. OE. clufðung(e fem.; ME. clofthounk and cloffynnge are the same word. Bosw.-Toller explains from clufu clove, bulb + þung masc. monkshood or hellebore. Cf. CLOVE-TONGUE.] A plant: see quots.
(Cockayne understood the OE. name to mean Ranunculus sceleratus; which is probable, since both clufþung and clufwyrt are glossed by Batrachion, an old name of Ranunculus. But the ME. name seems to mean a hellebore, as in Halliwells modern entry.)
