在美国，有2个主要天然块状细胞拟南芥（不包括阿拉斯加）。哥伦比亚抗体（西方尖）是主要发生在美国西部的人群的多态性复合物，在花卉形态和适应性的营养生殖模式中表现出极端的人口间变化。 A. uncinatum（东尖）是一组更均匀的人群，主要发生在美国东部的山区。这些痤疮的最独特的区别是块茎形态。 A. columbianum具有连续的父母和女儿块茎，而A. uncinatum的块茎则以细长的连接为单位。这2 sp。叶片的叶片形态和味道也有所不同。爱荷华州和威斯康星州的可拟南芥的拟南芥的拟南芥和威斯康星州的拟南芥的亚种群在块茎形态学上和其他与西方无蛋白粉种的小花环的小花和浅花的典型的种族相似，表明它们实际上是A. columbian的，它们在形态上相似。俄亥俄州和纽约的Aconitum的亲和力以及名称A. Noveboracense和A. Uncinatum SSP的状态。在这些州搬迁人口之前，无法解决诺夫堡。
There are 2 main natural groups of tuberous Aconitum within the USA (excluding Alaska). A. columbianum (western Aconitum)is a polymorphic complex of populations occurring primarily in the western USA which exhibits extreme interpopulation variation in floral morphology and in modes of adaptation for vegetative reproduction. A. uncinatum (eastern Aconitum) is a more homogeneous group of populations occurring primarily in the mountains of the eastern USA. The most distinctive difference between these aconites is in tuber morphology. A. columbianum has contiguous parent and daughter tubers, whereas A. uncinatum has tubers separated by elongate connectives. These 2 spp. differ also in leaf morphology and taste of the tubers. Aconitum populations of Iowa and Wisconsin were previously treated as A. noveboracense or as a subspecies of A. uncinatum, but they are morphologically similar in tuber morphology and in other respects to nonbulbiferous races of western Aconitum with small flowers and shallow nectaries, indicating that they are actually disjunct populations of A. columbianum. the affinities of Aconitum of Ohio and New York and the status of the names A. noveboracense and A. uncinatum ssp. noveboracense cannot be resolved until populations are relocated in these states.
