Riassunto

Il presente lavoro riporta i risultati dell'indagine floristica effettuata nella cittá di Chieti (Abruzzo) negli anni 1995–1999. Sono state censiti 423 taxa di rango specifico e sottospecifico, appartenenti a 240 generi e 73 famiglie. Sono state rinvenute alcune entitá interessanti quali Fumaria gaillardotii, nuova per l'Abruzzo, due ibridi naturali: Dactylis glomerata subsp. glomerata x D. g. subsp. hispanica ed Elytrigia repens x olivierii. L'analisi degli elementi corologici e delle forme biologiche mostra due diversi aspetti della flora di questa cittá. Nello spettro corologico dominano le specie Mediterranee rispetto a quelle ad Ampia Distribuzione; tra le prime le Eurime diterrranee costituiscono il contingente di maggiore consistenza in accordo con il gradiente geografico. Dallo spettro biologico si evidenzia un carattere particolarmente termofilo della flora, dominata in assoluto dalle Terofite, carattere che non sembrerebbe trovare riscontro nei fattori climatici, ma che può essere interpretato come un effetto del fenomeno “isola di calore”.

In the years 1995–1999 a research was carried out in order to Hst the urban flora of Chieti town (Abruzzo, Central Italy). By the field work 423 species of vascular plant of specific and subspecific hierarchic order spontaneous or escape and now spontaneously reproducing, have been recorded, belonging to 240 genera and 73 families. The analysis of chorological types according to biogeographycal features shows the mediterranean elements prevail, reaching 44,18%: among theese the Eurimediterranean are 26,25 % whilst the other Mediterranean reach 18% ca., reflecting a mesophilous aspect of this flora. The species having a wider distribution as Cosmopolitan, Subcosmopolitan, Paleotemperate, Paleotropical and Circumboreal cover 28,70% only of the total. The exotics ones are 10,52 %, more or less the same value pointed out in several Italian towns as Rome and Florence. On the contrary the analysis of biological types shows undoubtedly aspects of a termophylous flora: Therophytes (42,34%) prevail over all, followed by Haemicryptophytes (30,38%). Well represented are the Phanerophytes (13,39%) with species mainly belonging to primary vegetation, confined in some localities of the area. The Geophytes (10,76%) well adapted to the urban environment and able to survive to the vicissitudes and stresses of the anthropic impact are well represented.
