Census of South Australian plants (external link)     [genus Dodonaea]
Name derivation:
Dodonaea named after Rembert Dodoens (1517-1585), a Flemish physician and botanist, also known under his Latinized name Rembertus Dodonaeus. Humilis means dwarf, small; referring to the small habit.
Distribution:
Endemic to South Australia and found from Streaky Bay to Keith.
Status:
Native. Common in South Australia.
Plant description:
Dioecious spreading shrub to 1 m high. Leaves pinnate, to 3.5 cm long excluding the petiole, lateral leaflets 2-12, rarely as many as 14, cuneate, obovate to broad-obovate, rarely oblanceolate, concave above, 3-7-toothed or -lobed at the apex, viscous, glabrous or sometimes with sparse simple hairs on the mid-vein below. Terminal leaflet usually elliptic or obovate, entire or rarely toothed or divided, otherwise similar to the lateral leaflets. Flowers from solitary to a 3-5-flowered terminal cyme with red flowers, sepals 4, stamens 8. Flowering between November and March.
Fruit type:
Red-brown capsule 4-lobed, to 7 mm long and 6 mm wide, with dense glandular hairs.
Seed type:
Black ovoid seed to 2.5 mm long and 2 mm wide, with a wing around the margin.
Embryo type:
Folded.
Seed collecting:
Collect capsules that contain hard black seeds, usually when capsule is turning red or brown.
Seed cleaning:
Place capsules in a tray and leave to dry for 1 to 2 weeks. Then rub the capsules by hand 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:
From one collection, the seed viability was average, at 75%.
Seed germination:
This species has physiological dormancy that needs to be overcome for the seed to germinate (e.g. nicking the seed coat).
