Which has more species, Erythrina or Thalia?
Erythrina Erythrina is a genus of flowering plants in the pea family, Fabaceae. It contains about 130 species, which are distributed in tropical and subtropical regions worldwide. They are trees, growing up to 30 m in height. The generic name is derived from the Greek word ερυθρóς ("erythros"), meaning "red," referring to the flower color of certain species.
Erysimum Erysimum (wallflower) is a genus of flowering plants that includes about 180 species of popular garden plants and many wild forms in the botanical family "Brassicaceae". The genus "Cheiranthus" is sometimes included here in whole or in part. Erysimum has since the early 21st century been ascribed to a monogeneric cruciferous tribe, Erysimeae, characterized by sessile, stellate and/or malpighiaceous trichomes, yellow to orange flowers and multiseeded siliques.
