Abstract: This paper deals with the study on morphology and histology of the fruit of Gardenia jasminoides Ellis. var, grandiflora Nakai. Advanced apparatus and methods such as scanning electron microscope (SEM) were applied, The author discovered that the lateral membranes of fruits spread out into the fruit-cavity and formed tangerine, fleshy and dendroid pseudomembrane between earpels, which alternated with seed and wrapped it like a ball, Five planes of the sclereid of seed coat were thickened and its cell cavity was stuffed by pigment lumps. Parenchyma were full of Gardouin. The above-mentioned characteristics are clear, Those provide some important scientific bases for appraisal of it.
