Taxonomic fingerprints of Plantago atrata Hoppe – a Review

Abstract

Plantago atrata Hoppe (dark plantain; Plantaginaceae) is a lesser-studied narrow-leaved Plantain species and in the present review, we summarize the knowledge about the plant. The distribution of this alpine species and reported subspecies is described. Emphasis is made on P. atrata taxonomic features including botanical characteristics and phylogenetic discrimination via DNA barcoding and metabolic composition. The ecological significance of this plant species is discussed from floristic and nutrient value points of view. The collected information would serve as a basis for further in-depth research on physiological and phytochemical aspects of P. atrata, which would enable the understanding of this plant’s high-altitude adaptation and its possible contribution to beneficial applications for other organisms.
