Remarks In addition to the wild specimens of Acalypha herzogiana, also appear specimens of a cultivar of this species, usually from gardens or urban areas. This cultivar is of uncertain origin and is characterised by the showy terminal pistillate inflorescences formed by numerous densely clustered, ebracteate, pistillate flowers. It was studied by Steinmann & Levin (2011), who hypothesised that it is the result of homeotic mutation resulting in the stamens being replaced by styles.Published as part of Cardiel, José María, Muñoz-Rodríguez, Pablo, González-Berdasco, Álvaro & Montero-Muñoz, Iris, 2023, Catalogue and red list of Acalypha L.
