φύσει δὲ ἀπαράβλαστα πάντα καὶ διὰ τὴν ξηρότητα τῶν ῥιζῶν καὶ διὰ τὴν εἰς τὸ ἄνω φορὰν καὶ ἔτι τῷ μονόρριζα εἶναι καὶ τῷ βαθυτέρας ἔχειν. οὐδαμοῦ γὰρ οὐδὲν περιττὸν οὐδὲ παροχετευόμενον ἐκπίπτει τῆς τροφῆς ὥστε μὴ εἶναι βλαστήσεως ἀρχήν· ὅταν οὖν πάντα ταῦθ᾽ ὑπάρχῃ πᾶσι σχεδὸν ἀναγκαῖον τὴν φθορὰν εἶναι τελείαν·
