Wilbur) is a species of Myrica, native to Macaronesia (the Azores, Madeira, and the Canary Islands), and possibly also western coastal mainland Portugal.

The male flowers have four stamens and are normally produced in clumps close to the branch.

The female flowers, typically occurring in similar groups grow slightly further from the branch tips.

In Macaronesian islands it occurs most abundantly at altitudes of 600–900 m. The population in Continental Portugal may be native or naturalised following early importation from Madeira or the Azores (Rushforth 1999).

It is an invasive species in Hawaii (Vitousek et al. 1987), where it displaces native trees such as Metrosideros polymorpha, with profound impacts on nitrogen cycling (Vitousek & Walker 1989).
