Hutu Ascarina lucida var. lucida, photographed by John Smith-Dodsworth.

Belongs within: Angiospermae.
Contains: Eudicotyledoneae, Monocotyledoneae, Magnoliales, Laurales, Canellales, Piperales.

The Mesangiospermae were defined by Cantino et al. (2007) as the most inclusive crown clade including Platanus occidentalis but excluding Nymphaea odorata and Austrobaileya scandens; as such, it represents the clade of flowering plants excluding the basal ANITA grade. The clade is supported by molecular analyses, but reliable morphological synapomorphies have not yet been identified. The Mesangiospermae contains five well-supported clades—the monocotyledons, eudicotyledons, magnoliids, Chloranthaceae and Ceratophyllum—but relationships between these clades remain unsettled.
