[22] myrtus Asia: the myrtle flourished in damp places, and the thought here is probably of the famous fertile region about the Cayster in Lydia; cf.
Verg. G. 1.383 “volucres quae Asia circum dulcibus in stagnis rimantur prata Caystri” . The myrtle bore white blossoms (Aristoph. Birds. 1099“ ἠρινά τε βοσκόμεθα παρθένια
λευκότροφα μύρτα
”, and was sacred to Venus ( Phaedr. 3.17.3 “myrtus Veneri placuit” ); similarly Ariadne is compared to a myrtle-branch in Catul. 64.89, and Vinia herself in v. 91ff. to the hyacinth, and in v. 193ff. to the white parthenice and the flame-red poppy.
