late autumn pertaining to the latter part of autumn The use of φθινοπωρινός in JUD 1:12 should not be understood to imply that the fruit has already been picked, but rather that the trees in question have not produced fruit at all, and even in late autumn there is no productivity.

Moulton & Milligan — Vocabulary of the Greek NT
φθινοπωρινός, derived from φθινόπωρον (cf. P Cairo Zen Τ. 590204— B.C. 258), a compound from φθίνουσα ὀπώρα, ‘the concluding portion of the ém@pa,” and hence ‘‘ autumnal ”’: cf. Moulton Gy. ii. ὃ 106, p. 279f. In Jude!* the epithet is applied to false teachers, δένδρα φθινοπωρινὰ ἄκαρπα, ‘*autumn trees without fruit’’ (RV): they were barren at the very time when fruit might be expected (cf. Lk 135). See the full discussion of the word with many reff. in Mayor Ep. of Jude, p. 55 ff., and add from the papyri the calendar P Hib I. 2737 (B.c. 301-240) Ky lonpepla φθινοπωρινή.

(=I. p. 109) φθόγγος ἐναρμόνιος, and 777 φθόγγος [ἀ]ναγκαστικός, also P Leid V vit 6 (ili/iy A.D.) (=I. p. 29) πρὸς ἁρμονίαν τῶν ἑπτὰ φθόγγων ἐχόντων φωνὰς πρὸς τὰς κη φῶτα τῆς (σελήνης).
