The sexual status of Colebrookea (Labiatae)

Abstract

[221][222][223][224][225]. The sexual status of Colebrookea Smith (Labiatae) has been investigated and found to be dioecious and sexually dimorphic. Male flowers have a small non-functioning ovary and long exserted stamens. Female flowers have small staminodes inserted inside the corolla, and a gynoecium in which only one mericarp matures. The corolla is smaller in female flowers and the calyx larger. The mericarp is released within the calyx. The fruiting calyx enlarges after pollination, with calyx lobes reduced to plumose teeth.
