Question: Which genus has more species Adiantum or Nasturtium ?
Sentence (from "Nasturtium (genus)"): "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).
Relevant evidence: No
