The generic name Chasmanthe is made up of the Greek words chásma for "throat" and ánthe for "blossom" and refers to the elongated tubular shape of the flowers.
All three Chasmanthe species are only found in South Africa.
The genus Chasmanthe includes three species:
- Chasmanthe aethiopica ( L. ) NEBr. ( Syn .: Antholyza aethiopica L. , Antholyza floribunda Salisb. , Chasmanthe peglerae N.E.Br. , Chasmanthe vittigera (Salisb.) NEBr. , Petamenes aethiopica (L.) E. Phillips , Petamenes peglerae (NEBr.) E. Phillips , Petamenes vittigera (Salisb.) E. Phillips ): It occurs in the South African provinces of the Eastern Cape and Western Cape . Your stocks are considered stable.
- Chasmanthe bicolor (Gasp. Ex Vis.) NEBr. (Syn .: Antholyza bicolor Gasp. , Petamenes bicolor (Gasp. Ex Ten.) E. Phillips ): It occurs only at three localities in McGregor and Swellendam in the Western Cape. It thrives in open woodlands near rivers . Their populations are endangered by farming, dam building and invasive plant species.
- Chasmanthe floribunda (Salisb.) NEBr. (Syn .: Antholyza aethiopica sensu Burm. F. , Antholyza praealta Redouté , Chasmanthe floribunda var. Duckittii G.J.Lewis ex L.Bolus , Chasmanthe floribunda (Salisb) NEBr.. Var. Floribunda , Petamenes floribunda (Salisb.) E.Phillips ) : There are no more subtaxas.
