CONTRIBUTO ALLA CONOSCENZA DELLA FLORA DEL TERRITORIO DI VICARELLO (ROMA)

The results of a floristic research in Vicarello area (Bracciano, RM), during spring-summer 1992, are here presented; the area is included in the Mediterranean transition Region, at a height of 300-450 m a.s.l. - 480 entities, 8 of which introduced, subdivided into 71 families of vascular plants, have been recorded. Some of them are rare or not frequent in Latium, such as Moenchia erecta, Cerastium brachypetalum subsp. tenoreanum, Hypericum androsaemum, Cardamine amara subsp. grandifolia, Vicia lathyroides, Viola riviniana, etc. The general biological spectrum shows a great percentage of Hemicryptophytes (40%), higher then the value of Therophytes of about 10%. The general chorological spectrum shows a high percentage of Mediterranean entities (Steno- and Euri-, 34%) with a further increase when referred only to the meadows (43%). The european-asiatic elements increase in the woodlands.
