List of Symphyotrichum species explained

Symphyotrichum is a genus of flowering plants in the tribe Astereae which includes the commonly cultivated New York aster (S. novi-belgii) and New England aster (S. novae-angliae). Its species are widespread in the Americas, including as far north as subarctic North America to as far south as Chile, Argentina, and the Falkland Islands. One species has a native range extending into eastern Eurasia.

Most of the species in the genus are perennials. The flower heads have white, pink, purple, or blue ray florets surrounding white to yellow disk florets. The disk floret corollas become pink, purple, or brown after pollination. The three species in section Conyzopsis have reduced or absent ray florets.

Symphyotrichum is the type genus of subtribe Symphyotrichinae. There are 98 species in the genus, some with varieties, and thirteen named hybrids. The genus is split into five subgenera: Chapmaniana, Astropolium, Virgulus, Ascendentes, and Symphyotrichum. Most of the species had been classified within the genus Aster until it was confirmed to be polyphyletic. The American asters now are separated into monophyletic genera based on multiple phylogenetic studies.

Conventions

Conservation status codes follow the NatureServe conservation (NS) rounded global status scheme. Hybrids have a column for parents in place of conservation status. Not listed (NL) is not a NatureServe category but is used here to represent those left out of global status rankings up to G5 (including GNA and GNR) and those not in NatureServe. Type species for each clade are in a separate table.

Classification

Classification of Symphyotrichum

Subtribe Symphyotrichinae contains six genera. In addition to Symphyotrichum, these are Almutaster, Ampelaster, Canadanthus, Psilactis, and Sanrobertia, with Symphyotrichum being the largest at 98 species and thirteen named hybrids. The cladogram presented here for the subtribe is based on a combination of cytotaxonomic and morphologic data reported in multiple studies. Symphyotrichum is the type genus of the subtribe.

Classification within Symphyotrichum

Most of the species had been classified within the genus Aster until it was confirmed to be polyphyletic – as previously defined, the genus Aster contained groups of species with different most recent ancestors. The American asters were then separated into several genera based on morphological characteristics and phylogenetic studies.

Within Symphyotrichum, S. novae-angliae and S. turbinellum are monotypic within sections. S. novae-angliae is classified in the subgenus Virgulus. In 1994, it was placed in section Grandiflori, subsection Polyligulae. In 2002, it was segregated within its own section Polyliguli. The list follows the 2002 circumscription of section Polyliguli for the species. S. turbinellum is classified in the subgenus Symphyotrichum. It has been placed within its own section Turbinelli. It was previously placed in section Symphyotrichum, subsection Turbinelli. The list follows the more recent circumscription of section Turbinelli for the species.
