Melleodora from the Greek 'meli' meaning honey and 'odor' meaning smell, referring to the honey-like perfume of the species.

Plant description

Glabrous, resinous, viscid shrub to 4 m high. Branchlets often sparsely tuberculate. Leaves obovate to oblanceolate, sometimes narrowly elliptic, to 5 cm long and 11 mm wide, obtuse, mucronulate; normally sparsely tuberculate, green, grey-green (glaucous), the resin sometimes drying white, with 2 or 3 prominent longitudinal nerves; basal gland elongate, smaller gland at base of the minute apical mucro. Flower-spike simple with 1-3 globular golden flower-heads per axil. Flowering between May and September. Fruits are brown, narrowly oblong pod to 9 cm long and 1.5 cm wide, flat, raised over seeds alternately on each side. Seeds are hard, dark brown ovoid seed to 4 mm long and 2.5 mm wide. Seed embryo type is investing.

Seed collection and propagation

Collect seeds between October and December. Collect mature pods that are turning brown, with hard, dark seeds inside. Place the pods in a tray and leave to dry for 1-2 weeks or until the pods begin to split. Then rub the dried pods to dislodge the seeds. Use a sieve to separate any unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
