Sapindaceae
Acer opalus – Acer opalus
Acer opalus (arțar italian) crește de la o formă de arbust la un arbore de dimensiuni medii, cu o coroană ovoidală până la ovoidală. Crengile, scoarța și frunzele sale nu sunt deosebit de spectaculoase. Frunzele acestui arțar italian au o formă destul de variabilă; numărul de lobi variază de la 3 la 7. Vârfurile lobilor sunt ascuțite sau rotunjite. Fața superioară a frunzei este glabră, iar fața inferioară este inițial complet păroasă, ulterior doar pe nervurile principale. Tulpinile florale sunt, de asemenea, păroase, ceea ce reprezintă o caracteristică distinctivă a Acer opalus. Culorile de toamnă pot fi de la roșu până la roșu-maroniu intens, dar depind foarte mult de locație și de climatul local. Cele două fructe înaripate formează un unghi drept spre acut unul față de celălalt.
