'''''Nasturtium''''' is a [[genus]] of five [[species]] in the Family [[Brassicaceae]] (cabbage family), best known as containing the edible [[Watercress|watercresses]] ''Nasturtium microphyllum'' (''Rorippa microphylla'') and ''Nasturtium officinale'' (''R. nasturtium-aquaticum''). ''Nasturtium'' was previously synonymised with ''[[Rorippa]]'', but molecular evidence supports its maintenance as a distinct genus more closely related to ''[[Cardamine]]'' than to ''Rorippa'' ''[[sensu stricto]]'' (Al-Shehbaz & Price, 1998; Al-Shehbaz, Beilstein & Kellogg, 2006).
These plants are related to [[garden cress]] and [[Mustard plant|mustard]], noteworthy for a peppery, tangy (pungent) flavor. The name Nasturtium comes from the [[Latin]] ''nasus tortus'', meaning "twisted nose", in reference to the effect on the nasal passages of eating the plants. ''Nasturtium'' is not related to the genus ''[[Tropaeolum]]'' ([[Tropaeolaceae]]), popularly known as "[[Nasturtium (popular name)|nasturtiums]]".
