List of Acacia species

Several cladistic analyses have shown that the genus Acacia is not monophyletic. While the subg. Acacia and subg. Phyllodineae are monophyletic, subg. Aculeiferum is not. This subgenus consists of three clades.

Therefore, the following list of Acacia species cannot be maintained as a single entity, as this genus will be divided into 5 genera, Acacia, Vachellia, Senegalia, Acaciella and Mariosousa. This division was ratified on 30 July 2005 by the International Botanical Congress in Vienna.

The new type species of Acacia has become Acacia penninervis

The name Acacia is preserved for 948 Australian species, 7 in the Pacific Islands, 1 or 2 in Madagascar and 10 in tropical Asia. They all belong to the former subgenus Phyllodineae. Those outside Australia belong to the former sections Juliflorae and Plurinerves.

This new genus Acacia has six subgenera : Botrycephalae, Pulchellae, Plurinerves, Phyllodineae, Juliflorae, Lycopodiifoliae and Alatae (an artificial section)

The other species, distributed in the Indian Ocean, tropical Asia and tropical America will be classified under

  • Vachellia (former subgenus Acacia) : 163 species (pantropical)
  • Senegalia (former subgenus Aculeiferum) : 203 species (pantropical)
  • Acaciella (former subgenus Aculeiferum section Filicinae): 15 species (Americas)
  • Mariosousa 13 species, related to Acacia coulteri (A. acatlensis, A. centralis, A. compacta, A. dolichostachya, A. durangensis, A. mammifera, A. millefolia, A. russelliana, A. salazar, A. sericea, A. usumacintensis, and A. willardiana) (Americas)

Two former Australian acacias are classified under Vachellia, and another two under Senegalia.

Until a new list has been published, all species will still be called Acacia.
