[1] Same or similar glossing, variously, in other lexica; references at Photius upsilon56 Theodoridis. The headword, in the accusative case, must be extracted from somewhere (not necessarily the quotation given here, which other lexica do not have).
[2] Greek Anthology 6.104.3-4 (Philip of Thessalonike), a ploughman's dedication; cf. Gow and Page (vol. I, 310-311); (vol. II, 343); and further excerpts from this epigram at alpha 4721, beta 455, gamma 54, tau 994, omega 69, and omega 81. As Gow and Page point out (ibid.) Philip's word choice--a)/rotron, here in the dative plural--is awkward, inasmuch as it generally denotes an entire plough, whereas the reference is evidently to a curved part of a plough. Such a component is the plough-tail or plough-tree, the gu/hs (cf. gamma 474; Latin: buris), which connects to both the pole and the ploughshare and is fitted with a handle for the operator; cf. Smith (117-119).
[3] An error, as Gaisford pointed out: see LSJ s.v. But the word is sometimes spelled with a double nu; here ms G, Adler reports, reads u(/nnin.
