Title Μελέτη μορφολογικών ταξινομικών χαρακτήρων σε πληθυσμούς των taxa του section Genea του γενους Bromus(Poaceae) στην Κρήτη

Abstract Τhis project was an attempt to identify specimen collected from cretan populations of taxa of the section Genea, genus Bromus L. (Poaceae). For this purpose identification keys of this genus and the broader geographical area where used. A 36% of the specimen are uniquely identified with any key used, while 64% of the specimen are differently or not at all identified according to the key used.This was acclaimed to the fact that many characters overlapp between the different species. This agrees with the populational versus typological definition of species. Most effective key proved to be the multiple entrance key, proposed at the last revision of the section, but only after the incorporation of some modifications that are in agreement with the descriptions in the same paper. The study of histogramms of morphological, taxonomic characters of the cratan populations showed that some characters could contribute to uniquely identify the double or triple identified specimen and showed that other characters are not suitable to distinguish between different species, because of overlapping. Finally, a new multiple entrance key was proposed. This key was used to identify the cretan populations' specimen and proved to be more efficient than the used ones while uniquely identifying the 97% of them.
