Phyllodium
Phyllodium[1] est folium, praesertim plantarum angiospermarum, in quo e duabus folii partibus, petiolo nempe et lamina, altera deest, petiolus vero crescit supra quod de more est. In phyllodiis ergo petiolus, secus teres, applanatur. et photosynthesis in eo fit.[2]
Iuxta interpretationem Agnetis Arber folia Graminearum reapse phyllodia sunt, lamina eorum cum petiolo dicotyledonearum homologa;[3] quae autem hypothesis postea refutata est.[4][5]
