The present investigation was conducted to establish pharmacognostical profile for the leaves and flowers of Michelia champaca L. (Magnoliaceae) in order to establish its complete profile to aid in its identification and avoid confusion in taxonomic level for different species of the same genus. The study included macroscopical, organoleptical, microscopical and preliminary phytochemical analysis of the leaves and flowers. The study of the organoleptical evaluation revealed the presence of colour, odour and texture. The microscopic analysis showed the differences in cell structures, arrangement and shape of leaves and flowers. The physical characters of various solvent extracts showed the presence of colour, odour and consistency of the powdered leaves and flowers. Finally, the preliminary phytochemical analysis confirmed for the presence of alkaloids, saponins, tannins, glycosides, carbohydrates, amino acid, flavonoids and sterols in both leaves and flowers. The present findings may be used to establish the authenticity of leaves and flowers of Michelia champaca L. for their proper identification and standardization in order to collect raw plants for the preparation of herbal drugs.

A b s t r a c t A r t i c l e I n f oArchidendron chevalieri (Kosterm.) I.C. Nielsen (Leguminosae: Mimosoideae): is reported first time in India from Arunachal Pradesh. This species is differs from other Indian Archidendron species by having pot-form petiole gland; peduncle ca. 1.1-2 cm with sparsely pubescence; densely villous corolla; 46 stamens; 1.5 cm long filaments and yellow anthers. Detailed descriptions, photographs, habitat and ecology are provided for easy identification. Additionally, a comparison of the diagnostic characters between this species and Archidendron kerrii is given.
