* The Astereae consist of the asters, goldenrods, and related plants. Recent nomenclatural changes have removed almost all of the North American asters from the Aster genus itself. A general reference used here for this trib is John C. Semple's Astereae Lab website.

## Subtribe Bellidinae
### Bellis

* Bellis perennis, English lawn daisyBellis contains about 15 Old-world species commonly known as daisies. Of these, only the lawn daisy is known to have naturalized to any extent in New York or the rest of North America. A number of cultivars have been developed for horticultural purposes, and it's also considered to be a common lawn weed.

## Subtribe "eurybioid asters"

* The unplaced "eurybioid asters" include the genera Oreostemma, Herrickia, Eurybia, and Triniteurybia, of which, only Eurybia contains species that are native to New York.

### Eurybia

* Eurybia contains what Semple (2014) calls the "Eurybian Asters." It is separated here according to Semple's morphologically based intra-generic classification. Of the New York native Eurybia species, those of sect. Eurybia (Biotia) have heart-shaped (cordate) basal leaves, while those of sect. Calliastrum have oblanceolate or obovate basal leaves.
