The lable brād- seems to point towards a broad leafed species of →bisceop-wyrt; also cf. →brāde-lēac.
Cf. LA 166/20 þa bradan biscopwyrt; the compound (?) brād-bisceopwyrt (Cockayne 1962,III,4/30 reads brad bisceopwyrt) is not recorded in any dictionaries except the DOE; and the occurrence þa bradan bisceopwyrt in BT, s.v. bisceopwyrt.
Pettit (2001,XIV,41) also records other occurrences which possibly point towards the lemma being an autonomous plant name: "a remedy in Wellcome Historical Medical Library MS 46, fol. 144 (ed. Napier 1980: 325a) genim brade bisceopwyrt 7 and feldbisceopwyrt" and "BL MS Cotton Faustina A.X, fol. 115v (Ed C. vol. III, p. 292): twegra cynna bisceopwyrt".
