Which genus has more species Adiantum or Nasturtium ?
Adiantum Adiantum , the walking fern or maidenhair fern, is a genus of about 250 species of ferns in the Vittarioideae subfamily of the family Pteridaceae, though some researchers place it in its own family, "Adiantaceae". The genus name comes from Greek, meaning "not wetting", referring to the fronds' ability to shed water without becoming wet.
Tropaeolum incisum Tropaeolum incisum is a species of nasturtium, with flaring petals in shades of yellow and peach, when still in bud and on the outside darker, more orange-brown and sometimes stained purple, with creeping or climbing stems, in the wild up to about 60 cm long with deeply divided, blue-grey leaves, with undulating lobes, that grows on the dry eastern side of the southern Andes mountains.
