De plantis

Ἀλλὰ τὴν κρᾶσιν τοῦ ἄρρενος τῶν φυτῶν καὶ τοῦ θήλεος ὀφείλομεν διατυπώσασθαι οὐχ οὕτως ἀλλ’ ἄλλῳ τινὶ τρόπῳ, οἶον ὅτι τὸ σπέρμα τοῦ φυτοῦ ὅμοιόν ἐστιν ἐγκυμονήσει ζῴου, ἥτις ἐστὶ μίξις ἄρρενός τε καὶ θήλεος.

Καὶ ὥσπερ ἐστὶν ἐν τοῖς ᾠοῖς ὅτε γίνεται νεοσσός, ἔστιν ἐντεῦθεν καὶ ἡ τροφὴ αὐτοῦ μέχρι καὶ αὐτῆς τῆς ὥρας τῆς συμπληρώσεως καὶ τῆς οἰκείας ἐξόδου, καὶ τότε τὸ θῆλυ ἐκτίθησι τὸν νεοσσὸν ἐν μιᾷ ὥρᾳ.· οὕτω καὶ τὸ σπέρμα τοῦ φυτοῦ.
