14 Flowers lacking staminodes; filaments either connate below or free ( Lysimachia thyrsiflora); leaves “ punctate” with sinuous, elongate markings (visible with the naked eye, but more readily observed with 10× magnification and ideally with transmitted light). |
14 Flowers with staminodes alternating with the stamens; filaments free; leaves not " punctate" (see above). |
