%X Flowers of Thryptomene calycina contain two types of secretory tissue. Nectaries of the floral tube secrete a nectar rich in fructose and glucose, probably through the numerous stomata in the epidermis. The secretory cells are densely packed and have few vascular connections. The five anther connectives each terminate in a gland, which at anthesis contains large, thin-walled cells. The gland contains a hydrophobic material which stains positively for lipids and probably contains phenolics. This material is secreted through a pore at the end of the gland where it collects and mixes with pollen to form a food source for insects. This dual secretion of food materials would ensure that a wide range of pollinating insects visit the flowers.
