Crepeaceae

The Crepeaceae family is a small group of flowering plants that belongs to the order Malpighiales. This family is primarily composed of a single genus, *Crepea*, which contains only one species, *Crepea gigantea*, commonly known as the giant crepe myrtle or simply crepe myrtle. The family is notable for its distinctive flowers and historical taxonomic classification.

*Crepea gigantea* is a deciduous shrub or small tree native to the southeastern United States, particularly in states such as Alabama, Georgia, and Florida. It is characterized by its smooth, gray bark and clusters of small, crepe-like flowers that bloom in late summer to early fall. The flowers are typically pink, white, or lavender and are highly fragrant, attracting pollinators such as bees and butterflies. The plant’s common name, "crepe myrtle," derives from the delicate, paper-like texture of its flowers, which resemble crepe paper.

Historically, Crepeaceae was classified as part of the larger family Lythraceae, but molecular phylogenetic studies have since redefined its taxonomic placement. Genetic research indicates that *Crepea* is more closely related to certain groups within Malpighiales, leading to its recognition as a distinct family. This reclassification reflects advances in understanding plant evolutionary relationships through DNA analysis.

Crepe myrtles are widely cultivated as ornamental plants in warm temperate and subtropical regions due to their attractive flowers, foliage, and drought tolerance. They are often used in landscaping for their aesthetic appeal and low maintenance requirements. The plant’s hardiness and adaptability have contributed to its popularity in gardens and urban environments across the United States and beyond.

While the family remains relatively obscure compared to more widely recognized plant groups, its unique characteristics and historical taxonomic shifts continue to be of interest in botanical research. The study of Crepeaceae provides insights into plant evolution and the importance of revisiting traditional classifications with modern scientific methods.
