Interspecific hybridization between a native and an invading plant species, or two invading species, sometimes results in a new, sexually reproducing taxon. Several examples of such taxa have been confirmed by recent molecular and isozyme analyses. Further study of these new taxa, when recognized soon after their origin, should aim to elucidate the factors that influence their subsequent establishment and spread, thus leading to a better understanding of the processes that lead to successful speciation. Plant hybrids formed following a plant invasion provide great potential for the study of 'evolution in action'.
种间杂交，即在一个本地物种和一个入侵物种，或者两个入侵物种之间发生杂交，有时会产生一个新的、有性繁殖的分类单元。最近的分子和同工酶分析已经证实了几个这样的分类单元的存在。当这些新的分类单元在出现后不久就被识别出来时，对它们进行进一步的研究应该旨在阐明影响它们后续建立和传播的因素，从而更好地理解导致成功物种形成的过程。入侵后形成的植物杂种为“正在进行中的进化”的研究提供了巨大的潜力。
