Abstract:

The change of circumscription of Jarava (Stipeae) from a morphologically homogeneous section with nine species of the genus Stipa to a heterogeneous genus of ca. 60 species is criticized because of the lack of DNA data to support the change. The modification is considered inconvenient in terms of the ICBN article 14.1 on disadvantageous strict application of priority rules, due to the abundance of Stipa in South American arid regions, a fact which is reflected in the extensive use of the name Stipa by Latinamerican botanists.
