The study on flower morphology of four species viz. A.edulis, A.hypochondriacus, A.cruentus and A.caduatus revealed that the flowers were monoecious compond, pentamerous with circumscissle utricles. The flowers are arranged in glomerules each with an initial staminate flower and indefinite of pistilate flowers. Glomerules are crowded on axes which make up the spikes of the inflorescences. Each flower is subtended by bract with a sharp point. The perianths of the flowers are made up of five free tepals, male flowers have five stamens and female being a utricle. The one male flower and six female flowers are arranged in each cluster. The reproductive biology revealed that the number of flowers per inflorescences was species wise different. The species to species variation was observed. A. hypocondriacus L. had highest number flowers per inflorescences and lowest number of flowers per inflorescence on the species of A. edulis L.
