Species: Symphyotrichum ciliatum

Plantae - Anthophyta - Dicotyledoneae - Asterales - Asteraceae - Symphyotrichum - Kartesz (1999) reports Brachyactis ciliata ssp. laurentiana as the distinct local species Symphyotrichum laurentianum; B. ciliata is a synonym of Symphyotrichum ciliatum. Thus only plants considered B. ciliata in a somewhat strict sense (excluding eastern Canada's B. laurentiana) are recognized as Symphyotrichum ciliatum, which includes all the remaining New World plants, sometimes treated as B. ciliata ssp. angusta (syn. Aster brachyactis) (Kartesz 1999; Cronquist 1994); cf. Scoggan (1979).
