The headword noun is given first in the nominative plural (probably quoted from somewhere) and then in the nominative singular, the latter glossed.
[1] See LSJ s.v. for the extraordinary range of meanings which -- with equal propriety -- this noun can bear. There are several possibilities for the 'plant' alone, e.g. the aspen and the so-called Judas tree.
[2] Greek Anthology 6.174.5 (generally attributed to Antipater of Sidon), a dedication by three women of their spinning and weaving tools to Athena, again more fully at mu 1135; cf. Gow and Page (vol. I, 12-13); (vol. II, 37-38); and further extracts from this epigram at alpha 3750, alpha 3988, eta 190, omicron 340, and tau 38. Gow and Page note (ibid., 37) that the epigram's ascription to Antipater of Sidon is not entirely secure; see alpha 3750 note.
