Alexander Dyce, A General Glossary to Shakespeare's Works

bur-docks a plant too well known to have been noticed here, had not Mr. Beisly, in his Shakspere's Garden, etc., pp. 142-3, quite misrepresented the reading of the old eds. in the following line, “With burdocks, hemlock, nettles, cuckoo-flowers,” KING LEAR, iv. 4. 4 , where burdocks is Hanmer's highly-probable correction for“hoar-docks” and“hor-docks” of the quartos, and “Hardokes” and “Hardocks” of the folios. Mr. Beisly, however, erroneously supposes that the early copies agree in having “harlocks” (which, in fact, is Farmer's conjecture), and says, “This I consider should be charlock[s] or carlock[s], the ancient name of wild mustard,” etc.
