Acacia mearnsii De Wild., 1925 

Acacia mearnsii  Pl. Bequaert. 3(1): 62-63. 1925.


TENERIFE: Tegueste, Camino Urb. Las Rosetas close to TF-154 road, shrubland, 18.01.2017, F. Verloove 13419 (BR).


This species is a native of south-eastern Australia, but introduced into many countries for utilisation purposes (mostly as an ornamental shrub). It easily reproduces and, like other acacias, is often considered to be an invasive species ( Miller et al. 2011, Luque et al. 2014).

In Tenerife, Acacia dealbata  is a naturalised shrub, although some records doubtlessly refer to A. mearnsii  instead. The latter superficially resembles A. dealbata  . It is recognised by its green and shiny foliage (vs. foliage bluish-grey with lustrous leaflets), cream flowers (vs. bright yellow flowers) (Fig. 1View Figure 1) and pods softly appressed grey-pubescent to velutinous (vs. pods glabrous). Furthermore, in A. dealbata  , there is only a single gland at the base of the pinnae, whereas in A. mearnsii  on at least some leaves, multiple glands are present between the pinnae ( Maslin et al. 2019).

In Tegueste, Acacia mearnsii  was probably initially planted a long time ago and now survives. In the same place, a single individual was also observed of A. decurrens  (see earlier).
