A small, shrubby perennial to 90 cm high. Leaves to 13 mm long and 1.5 mm wide, usually narrowly oblong or elliptic to linear, rarely ovate or elliptic; mid-vein broad, flat, very prominent. Inflorescence a terminal or axillary cluster bearing 2-25 flowers; petals 5, rarely 4, spathulate to 10.5 mm long, white. Flowers throughout the year. The variety differs from the other variety found in South Australia by having longer but narrower leaf ratio of 4:1 or less (5:1 or greater in F. pauciflora var. gunnii), mid-vein broad, flat, very prominent (mid-vein inconspicuous in F. pauciflora var. gunnii) and 6-13 ovules (7-18 in in F. pauciflora var. gunnii). Fruits are small brown cylindrical capsule. 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.
