Family Asteraceae[edit]

The Asteraceae (or Compositae)

Subfamily Carduoideae[edit]

Tribe Cardueae[edit]

The Cardueae (syn. Cynareae) is a mostly non-native tribe of Asteraceae. It contains various thistles and knapweeds, many of which are considered highly invasive in the region.

Subtribe Carlininae[edit]

Carlina[edit]
Carlina vulgaris, Carline thistle
Carline thistle establishes on exposed soil but does not compete with taller dense vegetation.

Arctium[edit]
Arctium lappa, greater burdock
Only the two burdock species Arctium lappa (greater burdock) and A. minus (lesser burdock) are currently listed as naturalized in New York. Specimens of A. minus were apparently misidentified as A. tomentosum in the past.

Arctium is an Old World genus whose biennial plants have been introduced around the world, perhaps in part due to Velcro-like burrs that promote wide seed dispersal.

  4. ↑ Euro+Med Plantbase lists Centaurea gymnocarpa as an accepted species, while the Global Compositae Checklist lists it as a synonym of Centaurea cinerea. The IUCN Red List of Threatened Species, Version 2014.1, states "C. gymnocarpa belongs to the group known as the "cineraria" group. This group probably was once a single species when the land masses were united, but as islands were formed, new species evolved on each island. This means that today there are a number of closely related species of Centaurea in the Mediterranean growing on rocky seaward cliffs, all probably related to a common ancestor."
