| Abstract:
The present work is based on a research line of a larger project regarding the exploitation of some Mediterranean species from southern Italy for introduction in the Floricultural sector (PRO.FLO.MER.). From a taxonomic point of view the investigated species [Genista aetnensis (Biv.) DC., G. aristata Presl, G. aspalathoides Lam., G. cupanii Guss., G. demarcoi Brullo, Scelsi & Siracusa, G. gasparrinii (Guss.) Presl, G. madoniensis Raimondo, G. tyrrhena Valsecchi, Retama raetam (Forsskål) Webb subsp. gussonei (Webb) Greuter, Spartium junceum L.] belong to the Genisteae (Adams) Benth. Tribe. From a phytogeographical point of view they are characterized by a high level of endemism and by a very restricted localization. In order to reach a better knowledge and potential for ornamental exploitation, for each species, bibliographic, phytogeographical, autecological and phenological investigations were carried out. By a set of field surveys, the regional distribution range was defined. The observed aesthetic effects (i.e. compact habit’s and plentiful bloom) and their pioneer character suggest that some of these species are suitable as ornamental plants, especially in edged sites in dry and hot climates. | |
