Abstract	Abstract This paper provides information on morpho taxonomic observations of juvenile stages and seedlings in Leonotis nepetaefolia (L.) R. Br. Seedling morphology was observed upto 5th leaf stages. Morphological features of seedling like collet, hypocotyle, epicotyle, 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 identification and eradication of weed at juvenile stage. Leonotis nepetaefolia is a species of semi- succulent, perennial plant in the family Lamiaceae. It has a pungent Oregano like flavor and odor. Leonotis nepetaefolia is considered to be native to parts of Africa, the Arabian Peninsula, and India, although it is widely cultivated and naturalized elsewhere in the tropics where it is used as a spice and ornamental plant. Leonotis nepetifolia (L.) R. Br, commonly called dagga, klip dagga, or lion’s ear, has been used to effectively treat various diseases and other health problems for a long time because of its antimicrobial, anti-inflammatory, antioxidant, and analgesic activities. Several studies have attributed these biological activities to L. nepetifolia’s constituent secondary metabolites, such as alkaloids, phenolics, flavonoids, tannins, steroids, glycosides, coumarins, anthocyanins, and saponins. This review aims to examine the evidence-based ethnopharmacological uses of L. nepetifolia in the treatment of bronchial asthma, diarrhea, skin diseases, malaria, burns, cancer, diabetes mellitus, and rheumatism. However, although L. nepetifolia has great potential to treat these diseases, further isolation and identification of its therapeutic phytochemical constituents are required. In addition, the performance of its extracts and phytochemicals should be thoroughly tested in preclinical and clinical trials in order to ascertain their safety and efficacy, which will prove valuable in developing new medicines.
