Abstract

The scarlet sage, Salvia coccinea, was first detected in Northern Province, South Africa in 1905, in what is now Limpopo Province. However, its presence and suitability in South Africa remains undocumented. We conducted vegetation surveys to determine the actual distribution and to incorporate species distribution modelling in order to determine the potential distribution of this species. Twelve populations were documented from different localities. The species distribution model was successful in predicting areas that are climatically suitable for this species to survive in South Africa. The wide distribution and high density suggest a long residency time. Thus we conclude that its recent invasion of the wild has most probably originated in gardens.

猩红鼠尾草（Salvia coccinea Buc'hoz ex Etl。）在南非的发生记录和可能的入侵

摘要

猩红色的鼠尾草丹参（Salvia coccinea）于1905年在南非北部省（现为林波波省）首次被发现。但是，它在南非的存在和适用性仍然没有记载。我们进行了植被调查，以确定实际分布并结合物种分布模型，以确定该物种的潜在分布。记录了十二个来自不同地区的人口。物种分布模型成功地预测了适合该物种在南非生存的气候区域。广泛的分布和高密度意味着较长的居住时间。因此，我们得出结论，其最近对野生生物的入侵很可能起源于花园。
