Treatment appears in FNA Volume 20. Treatment on page 525. Mentioned on page 523.

Plants 7–200+ cm. Stems usually sparsely to ± densely hirsute, often glabrescent, sometimes glabrate proximally, sometimes entirely so (hirsute in lines in arrays). Leaves: abaxial faces paler than adaxial, with a dark, distinct reticulum, adaxial without impressed main veins; array leaves usually equal to mid cauline. 2n = 16, 32.


Phenology: Flowering Aug–Oct.
Habitat: Wet soils, often peaty, open to moderately shaded, margins of alluvial deciduous woods and alder thickets, swamp margins, edges of bogs, stream and lake shores, marshes, wet meadows, early-melting coastal or riparian snowbeds with boreal forbs (northern alpine and subarctic regions), roadside and drainage ditches
Elevation: 0–2000 m

Discussion

The following forms that pertain to var. puniceum are not recognized here: Aster puniceus forma blandus (Pursh) Lepage, forma candidus Fernald, forma colbyi Shinners, forma demissus (Lindley) Fernald, forma etiamalbus Venard, and forma rufescens Fassett. Variety calderi is a dwarf morphotype at the northern limit of the range that does not deserve taxonomic recognition. Hybrids of var. puniceum with the following species have been reported: Symphyotrichum lanceolatum (probably A. tardiflorus Linnaeus var. lancifolius Fernald), S. lateriflorum, S. urophyllum, and S. cordifolium.
