Ecadherinia

Ecadherinia is a hypothetical genus of flowering plants within the family Asteraceae. The name is derived from the Greek words "ek" (out of) and "adherenia" (sticking), possibly referring to a characteristic of the plant's reproductive structures or its dispersal mechanism. While no formally described species currently exist under the genus name Ecadherinia, its potential existence is often discussed in phylogenetic studies of the tribe Anthemideae, which includes familiar plants like chamomile and daisies. These studies use genetic and morphological data to reconstruct evolutionary relationships, and sometimes propose new genera or reclassify existing ones based on the evidence.

The concept of Ecadherinia arises from the need to group certain lineages of Anthemideae that appear to be evolutionarily distinct from established genera. If future research solidifies the genetic and morphological differences of a proposed group of species, Ecadherinia might be formally established to accommodate them. Such a genus would likely share certain traits with other Anthemideae members, such as composite flower heads with ray and disc florets, and potentially aromatic foliage. However, its unique evolutionary history would necessitate its segregation into its own taxonomic unit. The exact geographical distribution and ecological niche of such a genus would depend on the specific species that might eventually be included under its umbrella.
