Abstract:
In Senegal, few scientific investigations have been done on ornamental pteridophytes, while the
specific diversity of ornamental flora is becoming increasingly important due to the enhancement
of several species belonging to different taxonomic levels. It is therefore important today to take
an interest in this taxonomic group to contribute to a better knowledge of the ornamental flora of
Senegal. More specifically, this work this present work aims to determine the taxonomic
spectrum, the specific richness by family and the chorological spectrum of pteridoflore.
Methodology and results: This study was carried out in 84 horticultural stations in the city of
Dakar. In each site, a traveling inventory was carried out. Subsequently, the structure of the flora
was analyzed. The results made it possible to identify 11 ornamental ferns, belonging to 5 genera
united in 3 families. Among these species, none has been mentioned in the flora of Senegal. The
Dryopteridaceae family is predominant with 72.72% of the species recorded. In addition, the
genus Nephrolepis is the most diverse with 63.64% of the flora. In addition, this flora is
dominated by pantropical species which represents 45.45% of the flora or 5 species in total |
