Taxonomic investigation on Allium hirtovaginum group (Amaryllidaceae) from East Mediterranean area.

Within taxonomic studies on Allium sect. Codonoprasum from Mediterranean flora, populations belonging to A. hirtovaginum Candargy group were examined. Based on field investigation and herbarium surveyes, this group is represented by very critical and not well known taxa, distributed in the East Mediterranean, showing a marked morphological variability. Currently, the species referable to this group in addition to A. hirtovaginum are also A. pilosum Sibth. & Sm., A. aeginiense Brullo, Giusso & Terrasi and A. nerimaniae Koçyiğit & Kaya. Besides, other 13 species are here described as new to science, they are A. pythagoricum, A. pignattii, A. hippocraticum, A. abanticum, A. velutinum, A. carium, A. papillosum, A. adenanthum, A. smyrnaeum, A. pavonianum, A. denticulatum and A. compactatum. A detailed morphological description together with a careful illustration, as well as remarks on their karyology, phenology, ecology, geographic distribution, and taxonomic relationships are provided for each investigated species. An analytical key regarding all the species attributable to this group was processed too. [ABSTRACT FROM AUTHOR]
