Prostrate biennial or perennial herb to 70 cm long, with slender branches under 5 mm diameter. Leaves 1-3-pinnate with leaflets entire or divided; undivided leaflets and primary segments linear to narrow-lanceolate, to 6 cm long. Inflorescence in umbels with 4-15 white flowers with tiny yellow-brown midrib. Flowering between December and April. This variety differs from the other found in South Australia in having leaflets that are entire or divided, 6-15 times as long as wide, to 60 mm long, compared to Apium prostratum var. filiforme which have leaflets divided, 2-3 times as long as wide, to 20 cm long. Fruits are brown globular cluster with a number of seed segments. Seeds are orange-brown to 2 mm long and 1 mm wide, ribbed. Seed embryo type is linear under-developed.
Seed collection and propagation
Collect seeds between February and June. Collect maturing fruits by picking off the clusters that are turning brown. Place the fruits in a tray and leave to dry for one to two weeks. Then rub the fruits with a rubber bung to dislodge the seeds. Use a sieve to separate the 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. Seed viability is usually high.
