Structural, hystochemical and cytochemical characteristics of the stigma and style in Passiflora edulis f. flavicarpa (Passifloraceae)
Studies were carried out on anatomic aspects of the stigma and style of yellow passionfruit. The stigmatic style consisted of papillae, many layers of sub-epidermal cells and a central transmitting tissue. The stigma was of dry, unbranched, multicellular multiseriate papillate type and the cells wer...
