Editing Tropaeolum (section)

== Taxonomy ==
''Tropaeolum'' was previously placed in the family Tropaeolaceae along with two other genera, ''Magallana'' <small>[[Cav.]]</small> and ''Trophaeastrum''. The [[monotypic genus]] ''Magallana'' was characterised by having winged fruit, and the two species of ''Trophaeastrum'' lacked spurs. The genus ''Tropaeolum'' was diagnosed only by the absence of the characteristics of the other two genera. A molecular study undertaken in 2000 found ''Tropaeolum'' to be [[paraphyletic]] when the other two genera are segregated, so ''Magallana'' and ''Trophaeastrum'' were reduced to synonyms of ''Tropaeolum''. Tropaeolaceae was thus rendered monogeneric, a family of only one genus.<ref name="Andersson 2000">{{cite journal | title = A molecular phylogeny of Tropaeolaceae and its systematic implications |author1=Andersson, Lennart  |author2=Andersson, Stephan  |name-list-style=amp | journal = Taxon | volume = 49 | issue = 4 | year = 2000 | pages = 721–736 | doi = 10.2307/1223973 | jstor = 1223973}}</ref>
