Observations On The Seedling Morphology Of Ajuga bracteosa Wall. ex Benth. (Lamiaceae)

Vijai Malik*, Seema Anand

Abstract


This paper provides information on morphotaxonomic observations of juvenile stages and seedlings in Ajuga bracteosa Wall. ex Benth. Seedling morphology was observed upto 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 and, thus, have been found useful from taxonomic point of view in delimitation, identification and eradication of taxa at juvenile stage.
