carnasiales

Carnasiales is a historical name used in plant taxonomy to denote an order of flowering plants. The term has appeared in multiple classification schemes, but it is not recognized in modern, widely used systems such as the APG system. In its various forms, Carnasiales served as a way to group together several families whose relationships were unclear at the time.

The exact composition of Carnasiales varied among authors. Some circumscriptions included a small number of taxa, while others proposed a larger, more heterogeneous assemblage. Because of the diversity of included members and the reliance on largely morphological characters, the concept was controversial.

With the advent of molecular phylogenetics, studies failed to recover Carnasiales as a natural, monophyletic group. Consequently, the term fell out of routine use, and the families once placed in Carnasiales were redistributed into other orders according to different classification schemes. Today Carnasiales is primarily of historical interest, mentioned in discussions of the development of angiosperm taxonomy and in surveys of historical classifications.
