Arberella (Poaceae: Bambusoideae): A new genus from tropical America

  • Thomas R. Soderstrom
  • Cleofé E. Calderón


Arberella, a new genus of bambusoid grasses, is established, based on the newly described species,A. dressiert. Also belonging to this new genus are the taxa originally namedOlyra flaccida andRaddia costa-ricensis and several new species from Panama and Brazil which will be described later. The new genus is presented in a key to the genera of the tribe Olyreae, of which it is a member, and a key is given to the three species treated in this paper.
