First official record of naturalised populations of Solidago altissima L. var. pluricephala MC Johnst. (Asteraceae: Astereae) in Africa

摘要

Solidago altissima var. pluricephala is recorded for the first time as naturalised in Africa, with two populations detected in South Africa. One 0.5 ha population has been found near Harding and another of 403 shoots near Hilton, both inKwaZulu-Natal. A projected species distribution model for South Africa indicates that the grassland biome is the most at risk from invasion by this species. These plants are most likely garden escapees although we are uncertain how widely they are cultivated in South Africa. (C) 2016 SAAB. Published by Elsevier B.V. All rights reserved.
