The secretory glands of Asphodelus aestivus flower

Abstract: Various secretory glands are observed on Asphodelus aestivus flower, a common geophyte of Mediterranean type ecosystem. The floral nectary has the form of individual slits between the gynecium carpels (septal nectary). The septal slits extend downwards to the ascidiate zone of the carpels. The nectar is secreted by the epidermal cells of the slits, which differentiate into epithelial cells. The latter contain numerous organelles, among which endoplasmic reticulum elements and golgi bodies predominate. Nectar secretion results in an expansion of the space between the septa. The nectar becomes discharged through small holes on the ovary wall. Six closely packed stamens surround the ovary and bear numerous papillae at their basis. These papillae are actually osmophores, i.e. secretory structures responsible for the manufacture, secretion and dispersion of terpenic scent. A mucilage gland (obturator) exists between the lateral ovule and the ovary septa, giving a positive reaction with Schiff’s reagent. This gland secretes a mucoproteinaceous product to nourish the pollen tube and to facilitate its penetration into the ovary.
