• Resumen

  • Pennisetum longistylum, recently stated to be an older name for the well-known P. clandestinum (Cenchrus clandestinus), is shown to be a hybrid between P. clandestinum and P. villosum (C. longisetus). This is a rare hybrid only known from a few gatherings from the highlands of Ethiopia and Eritrea, the most recent one made in 1916. The new combination Cenchrus ×longistylus is proposed, and the names P. clandestinum and P. villosum are lectotypified.
