| Abstract | Abstract. Rumex vesicarius is an annual herb that has the capability of growing and flowering in three seasons: autumn, winter and spring in Riyadh, Saudi Arabia. Its reproductive growth is characterized by the formation of inflorescences. Each stem terminates in an inflorescence. The inflorescence is recognized as a raceme. Flowers are bisexual, formed within the inflorescence acropetally. The development of vegetative and floral buds (inflorescences) of Rumex vesicarius were investigated using light microscopy. Anatomical study revealed that floral differentiation of R. vesicarius occur0red in two distinct phases namely, the formation of the receptacle and the formation of the flowers. These two phases occurred in nine successive stages. This study is the first report of the phases and stages of development of inflorescences of R. vesicarius. Keywords: Herb, Inflorescence, Polygonaceae, Rumex vesicarius, Saudi Arabia. |
