The pistil of Solarium muricatum Aiton was composed of two carpels joined in a folded condition. The ovary was bilocular with a central placenta. The ovules were anatropous, unitegmic and tenuinucellar. The megaspore mother cell underwent meiosis in buds with the corolla shorter than the calyx, producing a linear tetrad. Embryo sac development was Polygonum-type. The embryo sacs were examined when corolla and calyx were the same length. In older ovules the hyposthase became visible. The cells in the center of the style formed a solid column of transmitting tissue. The papillate stigma was of the wet type. No anatomical or ultrastructural disturbances that would prevent seed set were observed in floral organ development.
