Notes
Acacia decurrens is endemic to New South Wales in Australia. However, its natural distribution is uncertain as a result of frequent naturalisation, caused by widespread plantings as an ornamental and in forestry plantations. It is now commonly naturalised in other parts of Australia, but also in, for example, South Africa and California. In some areas, it is considered to be a very troublesome weed ( Miller et al. 2011, Sunardi and Titiek 2017).
From the Canary Islands, it had not been reported yet ( Acebes Ginovés et al. 2010). A single shrub was found amidst a shrubland that mostly consisted of Acacia mearnsii in Tegueste, Tenerife. It may have been deliberately introduced there a long time ago.
This species is most readily distinguished from the other two Australian bipinnate-leaved acacias that are commonly grown in the Canary Islands (i.e. A. dealbata and A. mearnsii ) by its branchlets that are acutely angled by obvious winged ridges and its longer, narrowly linear leaflets ( Maslin et al. 2019).
