马先蒿属的花冠结构有四种类型：无齿型、有齿型、喙型和长管状。相似的花冠形式可能来自几个完全不相关的种群，而密切相关的物种。可能有各种各样的花冠。很明显，花冠的各种形式是沿着沿着重复的和独立的路线发展起来的。这种花冠形式的变化显然是适应性反应的结果。
There are four general types of corolla-structure in the genus Pedicularis, the toothless, the toothed, the beaked, and the long-tubed. Similar forms of corolla may rise from several entirely unrelated stocks, while closely related spp. may bear widely different forms of corolla. It is evident that the various forms of corolla have developed along repeated and independent lines. This variation in corolla-form is apparently the result of adaptive responses.
