Genus Coreopsis[edit]

Most of the naturalized Coreopsis plants found in New York are probably escaped ornamentals, native to the southern and midwestern parts of the United States. The exception is Coreopsis rosea, a rare Atlantic-coastal-plain endemic, which may also be found as a garden escape on Long Island and perhaps elsewhere.

Subtribe Rudbeckiinae[edit]

Genus Rudbeckia[edit]

Rudbeckia is a North American genus and very commomly found in New York, but only a few of its taxa are considered to be truly native to the state. Rudbeckia is here separated into the sections described by the Flora of North America.[1]

Rudbeckia sect. Macrocline[edit]

The most common true New York native Rudbeckia species is Rudbeckia laciniata, the cut-leaved coneflower or green-headed coneflower.

Rudbeckia sect. Rudbeckia[edit]

According to the New York Flora Atlas, in this section, only R. hirta var. hirta is truly native to New, but it hasn't been reported in at least 15 years. R. hirta var. pulcherrima is widespread, but is considered to be an introduced taxa in New York. However, R. triloba var. triloba is thought to be native in an unspecified part of the state, and introduced elsewhere.

  1. Rudbeckia triloba is probably native to parts of New York, and introduced in others.
  2. Some sources, including USDA-NRCS PLANTS database, consider R. fulgida var. sullivantii to be a synonym of R. fulgida var. speciosa

  1. Flora of North America: Asteraceae (tribe Heliantheae) subtribe Ambrosiinae
  2. The USDA-NRCS PLANTS database for Ambrosia artemisiifolia L. shows 3 varieties of the species with varying native status in New York. Other sources, including Flora of North America north of Mexico (2006) treat these varieties as synonyms as shown above.
Genus Xanthium[edit]

Although the New York Flora Atlas and the USDA-NRCS Plants database list three varieties of Xanthium strumarium, the Flora of North America does not recognize any varieties for this species, finding that their differences "mostly involved subtle differences in the burs."[1] The other sources used here follow that circumscription.
