Based on this evidence, the authors reason that these species, predominantly found growing on ultramafic soils on Palawan and Mindanao, are likely to have arisen as a result of the radiative speciation of a common ancestor in Borneo.
基于这一证据，其作者认为这些主要生长于巴拉望岛和棉兰老岛超基性土壤中物种，很可能是婆罗洲的共同祖先辐射种化（radiative speciation）的结果。
