| Résumé : |
A taxonomic revision of Bromus section Ceratochloa in Belgium. Two species groups within Bromus section Ceratochloa are easily identified: the Bromus carinatus and the B. catharticus group. Identification of (micro-) species within these groups, however, proves to be critical, especially in the former group. Five taxa have been identified: Bromus carinatus var. marginatus (syn.: B. marginatus), B. catharticus var. catharticus, B. catharticus var. rupestris (syn.: B. brevis), B. polyanthus and B. sitchensis. Bromus carinatus var. marginatus, B. polyanthus and B. sitchensis are reliably reported for the first time from Belgium (previous claims of the former proved to be erroneous), while the presence of genuine B. carinatus var. carinatus requires confirmation. The identity of the Belgian representatives of the Bromus carinatus complex is thoroughly discussed. The naturalization history, means of introduction, habitat preferences and ecology for all taxa are assessed and a selection of collections cited. For all taxa scans of a representative herbarium specimen and/or photographs are provided. At present only Bromus sitchensis is naturalized and obviously increasing, while B. catharticus var. catharticus appears to be a fairly frequent but mostly ephemeral introduction. The remaining taxa have not been recorded lately. |
