  Gynoecium of Sansevieria grandicuspis and vertical zonality of the ovary, gynoecium structural zonality after W. Leinfellner and septal nectary zonality were studied. There are a high parenchymatous ovary base with septal nectaries, ovary locules-the biggest part of the ovary with three locule cavities and the cavity of septal nectary, ovary roof-the part over the locules. There are three style channels and the end of septal nectaries. There is a long septal nectary that can be prolongated in both of them and opens with the secretory nectary splits. The gynoecium of this species has a short synascidiate zone, fertile hemisynascidiate zone and asymplicate zone that embraces the ovary roof, common style and stigma. Since there is a debate about the belonging of the Sansevieria genus to the Dracaena genus according to molecular data, it is interesting to study the mo.. Read More»
