    Several other yellow-flowered species of Agoseris, all called False Dandelion or Mountain Dandelion, are distinguished from this one by technical features of the fruit. The true Dandelion (Taraxacum) is also similar, but has minute pegs all over the top of the fruit and usually has bracts curved back beneath the involucre.
