Novedades nomenclaturales en Cenchrus s.l. (Poaceae: Panicoideae: Paniceae)

Abstract

Recientes estudios filogenéticos con datos morfológicos y moleculares aportaron evidencia sobre la monofilia de los géneros Cenchrus, Pennisetum y Odontelytrum y, por ello, se propuso su unificación y transferencia a Cenchrus, el cual tiene prioridad. Resultados preliminares de la revisión taxonómica del género Cenchrus s.l. para América (Gutiérrez, en preparación) permitieron detectar problemas nomenclaturales. Para resolver dichos inconvenientes, en el presente trabajo se presentan nueve lectotipificaciones: Cenchrus bambusoides Caro & E.A. Sánchez, C. brevisetus E. Fourn., C. pennisetiformis Hochst. & Steud. var. intermedia Chiov., C. roseus E. Fourn., Gymnotrix mexicana E. Fourn., Hymenachne montana Griseb., Pennisetum amoenum Hochst. ex A. Rich., P. cenchroides Rich. var. hamphilahense Terracc., P. ciliare (L.) Link var. anachoreticum Chiov., P. petraeum Steud., P. pringlei Leeke, P. tristachyum (Kunth) Spreng. subsp. boliviense Chase, y se propone un nombre nuevo para Gymnotrix crinita Kunth.Nomenclatural novelties in Cenchrus s.l. (Poaceae: Panicoideae: Paniceae). Recent phylogenetic studies with morphological and molecular data provided evidence on the monophyly of the genera Cenchrus, Pennisetum and Odontelytrum. Therefore, these studies propose the unification and transfer of species of Pennisetum and Odontelytrum to the genus Cenchrus, which has priority. Nomenclatural problems were detected when conducting a preliminary taxonomic revision of the genus Cenchrus s.l. from America (Gutiérrez, in preparation). To resolve these inconveniences, nine lectotypifications: Cenchrus bambusoides Caro & E.A. Sánchez, C. brevisetus E. Fourn., C. pennisetiformis Hochst. & Steud. var. intermedia Chiov., C. roseus E. Fourn., Gymnotrix mexicana E. Fourn., Hymenachne montana Griseb., Pennisetum amoenum Hochst. ex A. Rich., P. cenchroides Rich. var. hamphilahense Terracc., P. ciliare (L.) Link var. anachoreticum Chiov., P. petraeum Steud., P. pringlei Leeke, P. tristachyum (Kunth) Spreng. subsp. boliviense Chase and a new name for Gymnotrix crinita Kunth are here proposed.
