Abstract

Although there is extensive literature on aspects of floral structure and embryology in RANUNCULACEAE, the distribution of DEVELOPMENTal studies in the family is unequal. There are several studies on some genera but some other genera including Batrachium are less investigated or even unstudied. Embryological characteristics of Batrachium fluitans were was studied in this research. The flowers and buds, in different DEVELOPMENTal stages, were removed, fixed in FAA70, stored in 70% ethanol, embedded in paraffin and sliced with a microtome. Staining was carried out with Hematoxylin and Eosine. Results indicated that OVULEs are anatropous, bitegumic and crassinucellate. The megaspore tetrads are linear or T-shaped. The DEVELOPMENT of EMBRYO SAC conform to the Polygonum type and fertilization of central cell is prior to OVULE. Results showed that DEVELOPMENT of stamens is beginning with the formation of ovular shaped cell mass on the receptacle. They are five in number and surrounding style. Anther wall composed of an epidermis, an endothecium, a transitional layer and a tapetum layer adjusted to pollen mother cells. Tapetum cells remain in their position, at the DEVELOPMENTal stages, and they are of secretory ones. Microspore tetrads are tetrahedral. Microspores are not vacuolated and showed regular shape with condensed cytoplasm and centrally located nucleus. Mature POLLEN GRAINs are two-celled one.
