| Abstract | ||
| Floristic features of three habitat types in the Damietta Governorate namely: field crops, orchards and canal banks are described. The study habitats include 171 species related to 128 genera, grouped under 44 families with Gramineae attaining 36 species (21.05%), Compositae 21 species (12.28%) and Chenopodiaceae 15 species (8.77%), these are the main families. The recorded species comprise 98 annual species (57.31%), 8 biennial species (4.68%) and 65 perennial species (38.01%). The annual species are classified under three categories as follows: a) all year active annuals (14 species, b) winter-spring active annuals (64 species) and c) summer-autumn active annuals (20 species). According to the life-form spectrum the recorded species are classified into: therophytes (60.23%), cryptophytes (22.22%), chamaeophytes (7.60%), hemicryptophytes (7.02%), nanophanerophytes (1.75%) and parasites (1.17%). The floristic analysis of the study area reveals that, the Mediterranean elements (mono, bi - pluriregional) include 81 taxa (47.36%), Cosmopolitan element 28 species (16.37%), Palaeotropical 22 species (12.68%) and Pantropical 21 species (12.28%). These represent the major chorotypes. The other floristic categories are poorly represented. This indicates that, the study area is obviously belong to the Mediterranean Territory with the enterance of other elements to the area. | ||
