Aronia

See list of 3 species in this genus

Robertson et al. (1991) placed Aronia (eastern North America) in Photinia (Asia and Central America) based on morphological similarity and phylogenetic evidence. However, Aronia
is the older name. Therefore, unless Photinia is formally conserved, it needs to be subsumed under Aronia.

  • 1a. Pome black, generally falling from the plant in the fall and not persistent through the winter; abaxial surface of leaf blades, branchlets, and pedicels glabrous or nearly so
  • 1b. Pome red or purple, either long-persistent on the plant or falling in autumn; abaxial surface of leaf blades, branchlets, and pedicels varying from sparsely to densely pubescent (rarely one or more surfaces glabrous in A. floribunda)
    • 2a. Pome red; leaf blades usually varying from moderately to densely pubescent on the abaxial surface, turning bright red in the fall
    • 2b. Pome purple; leaf blades usually varying from sparsely to moderately pubescent on the abaxial surface, not or only partially turning red in the fall
