Crocanthemum
Crocanthemum is a genus of flowering plants in the family Cistaceae. They are native to both North and South America where they are widespread.

"Crocanthemum" are herbaceous perennials or subshrubs with alternate leaves. With the exception of species in California, they generally produce two types of flowers: showy, yellow chasmogamous (cross-pollinated) produced earlier in the growing season, followed by cleistogamous (self-pollinated) flowers that are smaller and lack petals. All species of "Crocanthemum" are fire tolerant and are found in open habitats.

Although the genus was first named in 1836 to encompass New World species of "Helianthemum", it generally went unrecognized by taxonomists and its species were included in a broad concept of "Helianthemum" throughout much of the 1800s and 1900s. However, phylogenetic studies in 2004 and 2009 indicated that the New World species of "Helianthemum" were more closely related to "Hudsonia" than Old World "Helianthemum". This required the resurrection of the genus "Crocanthemum" in order to maintain monophyly.
