Abstract

Impatiens nguruensis Pócs is described from the Nguru Mountains, part of the Precambrian chain of isolated crystalline mountains forming the Eastern Arc of Tanzania. It differs from the related Impatiens ukaguruensis Grey-Wilson by its deeper crenulate leaf margin with only 10–15 teeth at each side (around 20 in I. ukaguruensis ), by the narrower dorsal petal with straight lower margin and by the much less incurved spur of the lower petal. It is the second known endemic species of Impatiens in the Nguru Mts.
