Family Asteraceae[edit | edit source]

The Asteraceae (or Compositae)

Subfamily Carduoideae[edit | edit source]

Tribe Cardueae[edit | edit source]

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 | edit source]

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

Arctium[edit | edit source]
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.

Centaurea[edit | edit source]
The subgeneric classification of Centaurea (knapweeds) used here is based on Hilpold et al. (2014).[1]
Centaurea identification[edit | edit source]
Four of the most common and invasive knapweed species can often be distinguished by the involucre bracts, the scale-like structures surrounding the inflorescence, just below flower petals.[1]
  • Centaurea stoebe (spotted): Bracts are black tipped, tip and upper margin have soft, spine-like fringe, Center spine shorter than others.
  • Centaurea jacea (brown): Bracts are somewhat hairy, with broad, thin papery margins. Center of bract is dark brown.
  • Centaurea nigra (black): Bracts are oval-shaped with broad, comb-like, dark brown or black fringed margins. Fringe length up to 3 times as long as bract width.
  • Centaurea × moncktonii (meadow, brown × black): Bracts are light to dark brown, roundish, with thin papery margin with fringes about equal width of bract center.

Centaurea subg. Centaurea sect. Centaurea[edit | edit source]
Centaurea stoebe
spotted knapweed
Centaurea sect. Centaurea contains spotted knapweed (Centaurea stoebe ssp. micranthos), which has widely naturalized in much of North America , including New York State, where it is considered highly invasive.

  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."
  5. Centaurea paniculata checklist entries were based on reports only. No known specimens from New York exist. It is similar in appearance to Centaurea stoebe.
Centaurea subg. Centaurea sect. Phrygia[edit | edit source]
Centaurea × moncktonii
meadow knapweed
Centaurea sect. Phrygia, in New York State, contains three moderately invasive species of knapweeds, cumulatively known as the Centaurea jacea complex, and gradations of hybrids between possibly all three of them. The named hybrid Centaurea × moncktonii (C. jacea × C. nigra) is morphologically variable, and some individuals appear to have a similarity to C. nigrescens, possibly resulting from hybridization between all three species.
