摘要

在莫桑比克赞比西亚省纳穆利山的花岗岩露头和草地上发现了一新种——纳穆利花(Coleus namuliensis)。它以前曾被与pleectranthus caudatus混淆，pleectranthus caudatus是一种局限于莫桑比克-津巴布韦边境Chimanimani山脉的石英岩露头的物种，本文正式确定了Coleus的新组合。讨论了其他可能混淆的物种，并提供了使用属名Coleus而不是Plectranthus的理由。尽管分布范围有限，但C. namuliensis和C. caudatus目前都被认为是最不受关注的保护物种，尽管气候变化可能对它们的生存构成长期威胁。

Coleus namuliensis and Coleus caudatus (Lamiaceae):a new species and a new combination in the Afromontane flora of Mozambique and Zimbabwe

The new species Coleus namuliensis (Lamiaceae) is described from the granite outcrops and grasslands of Mt Namuli in Zambezia Province of Mozambique. It has previously been confused with Plectranthus caudatus, a species that is restricted to the quartzite outcrops of the Chimanimani Mountains on the Mozambique-Zimbabwe border for which the new combination in Coleus is formalised in this paper. Other potential confusion species are discussed and a rationale for applying the generic name Coleus rather than Plectranthus is provided. Despite their highly restricted ranges, C. namuliensis and C. caudatus are both considered to have a conservation status of Least Concern at present, although climate change may pose a longer-term threat to their survival.
