Ceratocephala (plant)

Ceratocephala is a genus of flowering plants in the buttercup family, Ranunculaceae. The genus is characterized by its small, delicate, annual herbs. They are typically found in wet or damp habitats, such as marshes, ditches, and seasonally flooded areas. The plants are generally low-growing, with finely dissected leaves and small, inconspicuous flowers. These flowers are usually white or greenish-white, and possess several petals. The fruits are distinctive, being achenes with hooked or horned structures, giving rise to the genus name, derived from the Greek words "keras" (horn) and "kephale" (head). The hooked achenes aid in seed dispersal via animal fur or other surfaces.

While the genus is relatively small, its exact species composition is sometimes debated, with taxonomic revisions occurring periodically. Many species exhibit a wide geographic range, with overlapping distributions and variations in morphology. Further research is often needed to clarify species boundaries and genetic relationships within the genus. The ecological roles of Ceratocephala species are relatively understudied, although their presence in wetland communities suggests they may play a role in nutrient cycling or provide habitat for certain insects.

Distinguishing Ceratocephala from similar genera in Ranunculaceae requires careful examination of floral and fruit characteristics, along with consideration of habitat preference. Microscopic analysis may be necessary for definitive species identification.
