Common names: Southeastern annual saltmarsh aster
Introduced

Synonyms: Symphyotrichum squamatum (Sprengel) G. L. Nesom
Treatment appears in FNA Volume 20. Treatment on page 482. Mentioned on page 481.

Plants 30–150 cm. Stems simple or branched basally. Heads 30–100 in open, diffuse arrays, secund on primary branches longer than peduncles. Involucres 5–7 (–8) mm. Phyllaries 18–24 (–30), subulate to lanceolate (often broadly so), green zones broadly lanceolate, absent from proximal portion. Ray-florets 21–28 (–38) in (2–) 3 series; laminae white (drying white or lavender), 1.3–1.7 (–2) × 0.2–0.3 mm, shorter than pappi, drying in inward curls, rarely coiling. Disc-florets (3–) 7–14, 4–4.9 mm. Cypselae 1.5–2.6 (–3) mm; pappi 4–5.1 (–5.3) mm. 2n = 20.


Phenology: Flowering Jul–Nov.
Habitat: Salt marshes, brackish marshes
Elevation: 0–10 m

Discussion

The name Aster subulatus Michaux var. sandwicensis (A. Gray ex H. Mann) A. G. Jones (Brinttonia 36: 465. 1984) has priority at the varietal level; the combination in Symphyotrichum has yet to be made.
