Two new species of Barleria subg. Barleria (Acanthaceae) are described from the Soutpansberg Centre of Plant Endemism in Limpopo Province of South Africa: Barleria soutpansbergensis and B. spinosissima. The habitat requirements, conservation status and taxonomic affinities of each species are discussed. Barleria soutpansbergensis is considered to be closely allied to the widespread and frequently cultivated southern African species B. obtusa, whilst B. spinosissima is morphologically most similar to B. bremekampii which has a restricted distribution in northern South Africa and Zimbabwe. Remarkably, the two new species are postulated to occasionally hybridise within the Soutpansberg. Both species are currently assessed as of Least Concern despite their restricted ranges. Barleria spinosissima is noted to be amongst the most densely spiny species of Barleria and, indeed, is a contender as one of the spiniest species of plant in South Africa.

Barleria subg的两个新种。Barleria (Acanthaceae) 描述于南非林波波省的 Soutpansberg 植物特有性中心：Barleria soutpansbergensis和B. spinosissima。讨论了每个物种的栖息地要求、保护状况和分类亲缘关系。Barleria soutpansbergensis被认为与广泛且经常栽培的南部非洲物种B. obtusa密切相关，而B. spinosissima在形态上与B. bremekampii最相似在南非北部和津巴布韦分布有限。值得注意的是，这两个新物种被假定偶尔会在 Soutpansberg 内杂交。尽管范围有限，这两个物种目前都被评估为最不关心的物种。Barleria spinosissima被认为是Barleria中刺最密集的物种之一，并且确实是南非最刺的植物物种之一。
