Leaf-blade elliptic, oblong, obovate or ovate, to 8 mm wide, flat or with margins loosely to tightly revolute; midrib inconspicuous or prominent, linear to flat; surfaces greyish yellow-green, glabrous to densely covered in hairs; short-shoot leaves similar. Flowers 1–19 in terminal or axillary clusters or solitary. Calyx 5-lobed, to 10 mm long and 2 mm wide, glabrous to densely hairy; petals to 15 mm long; stamens 6; style-branches 2 or 3; ovules usually 2 or 3. Flowers throughout the year. Fruits are brown cylindrical capsule. Seeds are light brown, ovoid seed to 2 mm long and 1 mm wide. Seed embryo type is spatulate, fully developed.
Seed collection and propagation
Collect seeds between January and December. Look at the tip of branches for dried flower heads. Collect the heads that are cylindrical, brown, slightly fat at the base. This should contain small ovoid seed. Place the flower heads in a tray and leave to dry for at least a week. Then rub the dried heads gently to dislodge the seeds. Use a fine sieve to separate the seeds from the unwanted material. Be careful as the seeds are very small. 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. Seed set can be low but viability is high. Seeds are non-dormant, viable seed should germinate readily.
