Bradleya 33/2015 pages 82–83 Transfers from Polianthes into Agave (Asparagaceae/Agavaceae): new combinations Joachim Thiede Schenefelder Holt 3, 22589 Hamburg, Germany (email: [email protected]) Summary : For two recently published species of Polianthes , P. alboaustralis E.Solano & Ríos- Gómez and P. cernua Art.Castro, J.G.González & Aarón Rodr., binomials in Agave are proposed: Agave alboaustralis (E.Solano & Ríos-Gómez) Thiede comb. nov. and Agave neocernua Thiede nom. nov. Zusammenfassung : Für zwei kürzlich veröf - fentlichte Arten von Polianthes , P. alboaustralis E.Solano & Ríos-Gómez und P. cernua Art.Castro, J.G.González & Aarón Rodr., werden Binomen in Agave veröffentlicht: Agave alboaustralis (E.Solano & Ríos-Gómez) Thiede comb. nov. und Agave neocernua Thiede nom. nov. Most phylogenetic studies of Agave L. and re - lated genera (Asparagaceae/Agavaceae) thus far published, based on molecular data (Bogler & Simpson, 1996; Bogler et al ., 2006; Good-Ávila et al ., 2006) or morphological data (Hernández-San - doval, 1995; Tambutti in Eguiarte et al ., 2006), showed that the small genera Manfreda Salisb., Polianthes L. and Prochnyanthes S.Watson are nested within the large genus Agave , thus ren - dering Agave as traditionally circumscribed para - phyletic. The sole exception is the molecular AFLP study of Gil-Vega et al . (2007) which groups Manfreda , Polianthes and Prochnyanthes sepa - rate from and not nested within Agave . For a taxonomic synopsis, Thiede (2001) con - verted these phylogenetic results into classifica - tion and suggested a monophyletic re-circum- scription of Agave : Manfreda , Polianthes and Prochnyanthes were included in Agave and to - gether classified as Agave Subgenus Manfreda Figure 1 Agave coetocapnia (M.
