Morphotaxonomic observations on juvenile and seedlings stages of Lagerstroemia speciosa were observed upto 6th leaf stages during germination in natural habitat. The features of seedling like collet, hypocotyl, epicotyl, shape and arrangement of paracotyledons, leaf base, colour, phyllotaxy etc. represent high level of constancy within taxon and thus, have been found useful from taxonomic point of view in identification and conservation of this species at juvenile stage itself which facilitate a healthy recruitment.
