摘要：

Generic boundaries of the South American genus Streptostachys (five species) are explored and compared with allied genera of the tribe Paniceae. On the basis of morphological, anatomical and molecular characters two new genera are proposed, Oncorachis based on Streptostachys macrantha and S. ramosa, and Sclerochlamys for Streptostachys reigidifolia. The phylogenetic position of the new genera and Streptostachys within Paniceae is evaluated.
