Seedling Morphology of Two Species of Nepeta L. (Lamiaceae) and its Taxonomic Implication

Vijai Malik

Abstract


The present study was carried out to highlight the morphotaxonomic observations of juvenile stages and seedlings in 2 species of Nepeta up to 5th leaf stages. Morphological features of seedling like collet, hypocotyl, epicotyl, shape and arrangement of paracotyledons, leaf base, colour, phyllotaxy, number of veins etc. represent high level of constansy within taxon. These characters and features of seedlings have been found useful from taxonomic point of view in solving taxonomic problems, circumscription, delimitation, identification and conservation of taxa at juvenile stage.

Keywords
