Here we clarify that areal-type of a genus is defined by concluding distributions of all species in the genus, therefore specific distribution types are not the same as their generic areal-types except monotypic genera. Similarities of composition of areal-types between compared regional floras do not necessarily represent their floristic similarities because the same generic areal-type can be composed by different genera from different plant families.

根据植物区系学理论,属的分布区是该属内所有物种的分布区的集合,除单种属外,不能直接套用属分布区类型作为该属内各个种的分布区类型;亲缘关系疏远的不同植物属可以有同样的分布区类型,若把不同地区植物区系各地理成分的比例关系的类似性解读成各地区间植物区系的亲缘关系,显然是不适合的。
