κοινοῦ δὲ τοῦ πάθους ὄντος ὁμοίως ζώων τε καὶ φυτῶν κοινήν τινα δεῖ καὶ τὴν αἰτίαν ζητεῖν· ἐπεὶ κἀκεῖνο ὅμοιον ἔν τε τοῖς σπέρμασι καὶ ἐν τοῖς ζώοις ὥστε μὴ εὐθὺς ἀλλὰ τριγονήσαντα μεταβάλλειν· ἅπαντα γὰρ κατὰ μικρὸν ἐξαλλοιοῦται καὶ μεθίσταται. τὸ δ᾽ ἐπὶ τῶν δένδρων ἀνάπαλιν εὐλόγως· ἀσθενέστατα γὰρ ἐν ἀρχῇ καὶ μάλιστα ὅταν ἐκ σπέρματος.
