Other claims from this paper (11)

Observation Nuclear and chloroplast sequence datasets were largely congruent.
Observation Asterid outgroup analyses supported Menyanthaceae monophyly.
Observation Menyanthes trifoliata and Nephrophyllidium crista-galli formed a sister clade to the rest of the family.
Observation Most Nymphoides species formed one deeply nested clade, excluding N. exigua.
Observation Floating leaves appear derived within the family.
Observation Villarsia formed a paraphyletic grade toward Nymphoides.
Observation A shallow Villarsia clade included six named species.
Observation South African Villarsia manningiana and V. capensis formed an isolated clade.
Observation A heterogeneous clade mixed Villarsia, Liparophyllum and Nymphoides taxa.
Recommendation Nymphoides exigua should be restored to Villarsia.
Recommendation Villarsia should be subdivided, with its strict sense restricted to South African taxa.
