C. Semple et al. 2002). Some species, notably the type of the genus, Aster amellus Linnaeus, have a large number of cultivars. The genus name is the type of the family name Asteraceae. As circumscribed here, Aster excludes members of the Crinitaria-Galatella-Tripolium complex, which are closer to the Bellidinae (Bellis, Bellium, Bellidiastrum; O. Fiz et al. 2002). Analysis of molecular data shows that Aster in the strict sense includes Diplactis, Kalimeris, Heteropappus, and a few other eastern Asiatic segregates. The relationship of Aster in the strict sense to other Astereae genera is unclear, and the delimitation of subtribe Asterinae in the sense of G. L. Nesom (1994b) is still uncertain.</p> |tables= |references= }}<!-- --><div class="treatment-key"> ==Key== <div class="treatment-key-group"> {| class="wikitable fna-keytable" |-id=key-0-1 |1 |Plants scapiform, to 30 cm; basal leaf blades oblanceolate to spatulate, 10–112 mm, cauline blades lanceolate to linear-lanceolate, 7–43(–50) mm, margins entire; heads borne singly; phyllaries lanceolate to lance-oblong, subequal; rays pink, white, or lavender (arctic-alpine) |[[Aster alpinus|Aster alpinus]] |-id=key-0-1 |1 |Plants leafy-stemmed, to 150(–300) cm; basal leaf blades oblanceolate, 300–500 mm, cauline blades oblanceolate to lanceolate, 40–180 mm, margins coarsely serrate or entire; heads borne in corymbiform arrays; phyllaries ovate to linear-lanceolate, unequal; rays pale lavender or purple (escaped from cultivation) |[[Aster tataricus|Aster tataricus]] |} </div></div><!-- -->{{#Taxon: name=Aster |author=Luc Brouillet |authority=Linnaeus |rank=genus |parent rank=tribe |synonyms=Asteromoea;Diplactis;Heteropappus;Kalimeris |basionyms= |family=Asteraceae |illustrator=Yevonn Wilson-Ramsey |distribution=North America;Eurasia. |reference=None |publication title=Sp.
