Bastard gumwood
Taxonomy & Nomenclature
Synonym/s: Psiadia rotundifolia (Roxb.) Hook.f.; Solidago rotundifolia Roxb.
Conservation Status
Extinct in the wild
Last record: 1986/2009
IUCN RedList status: Extinct in the Wild
This species was considered extinct before the start of the 20th century. Still listed as Extinct by (Humphreys et al., 2019).
A wild tree was discovered on a cliff in December 2009. Along with one individual in cultivation they comprise the total living population of the species. It's survival, however, is highly unlikely.
