Abstract

Infraspecies identity of Verbesina encelioides (Cav.) Benth. and Hook. (Asteraceae) from Libya.

Abstract

Background and Objective: Verbesina encelioides (Cav.) Benth. and Hook. belongs to the family Asteraceae, growing in roadsides and waste places, it was previously recorded as a new addition to the flora of Libya at the generic and species level without determining its infraspecies status. The aim of this study was to determine infraspecies status of this species. Materials and Methods: The plant is reported to be widely distributed in Tripoli as roadside, waste places, garden species and in disturbed habitats. Flowering and fruiting specimens of V. encelioides were collected from many places in Tripoli and brought to the herbarium of the Department of Botany, Faculty of Sciences, University of Tripoli and subjected to detailed morphological examination, which confirmed that it is belongs to subsp. encelioides. Results: The finding of this study is adds a new taxon to the flora of Libya. Information about its morphological features, biology, ecology, distribution and invasiveness were provided. Conclusion: In this study, Verbesina encelioides subspecies encelioides is discovered and recorded in the flora of Libya, which is previously identified and recorded at species level without determining the infraspecies identity, therefore this finding is significant to taxonomists and readers because it adds a new taxon to the flora of Libya.
