Scholz, H.: On the identity of Brachypodium firmifolium (Poaceae) from Cyprus. — Willdenowia 37: 215–220. — ISSN 0511-9618; © 2007 BGBM Berlin-Dahlem. doi:10.3372/wi.37.37111 (available via http://dx.doi.org/)
Brachypodium glaucovirens is the correct name for B. firmifolium formerly regarded either as a Cyprus endemic or as a synonym of B. sylvaticum. The most important diagnostic features against B. sylvaticum are the erect racemes and finely prickled to shortly hairy longitudinal ribs on the adaxial leaf blade surface. Constancy of these characters was proven by cultivation in experimental plots (source plants from Cyprus and the S Aegean region). A key to the species and its relatives is provided. The names B. glaucovirens and B. firmifolium are lectotypified.
