在广泛的野外研究和植物标本库研究的基础上，对高度可变的通菜属(Polemoniaceae)进行了修订。采用聚集型、异型和细毛型三种植物系统。在聚合草中发现了7个地理亚种，分别为Formosis sima、Aggregata、Bridgesii、Collina、tenuata。Weberi亚种。11月，和坎迪达。在它们的地理和育种关系上，前五个亚种是地理小种，最后两个亚种是半种。在I.arizonica和I.tenuituba中描述了地理变异，但在分类上没有被识别。当地的种族变异在该组中很常见，并列出了大多数分类群的例子。聚合草与细叶锦鸡儿之间的杂交发生在局部。
The highly variable Ipomopsis aggregata complex (Polemoniaceae) is revised on the basis of extensive field and herbarium study. A three-species system consisting of I. aggregata, I. arizonica, and I. tenuituba is adopted. Seven geographical subspecies are recognized in I. aggregata, namely, subspecies formosissima, aggregata, bridgesii, collina, attenuata. weberi subsp. nov., and candida. In their geographical and breeding relationships the first five subspecies are geographical races, and the last two are semispecies. Geographical variations are described but not recognized taxonomically in I. arizonica and I. tenuituba. Local racial variation is common in the group, and examples are listed for most taxa. Hybridization occurs locally between I. aggregata and I. tenuituba.
