Name derivation:
Dodonaea named after Rembert Dodoens (1517-1585), a Flemish physician and botanist, also known under his Latinized name Rembertus Dodonaeus. Intricata means entangled; alluding to the difficulty in recognizing this species from other Dodonaea species.
Distribution:
Endemic to South Australia and found in the Gawler Range on Eyre Peninsula, growing on granite hills and rocky outcrops in association with Melaleuca uncinata, M. rhaphiophylla, M. lanceolata and Triodia irritans.
Status:
Native. Locally common but uncommon for South Australia.
Plant description:
Dioecious spreading shrub to 1 m high. Leaves simple, petiolate, oblong or rarely oblanceolate or narrow-elliptic, truncate-emarginate or sometimes obtuse or irregularly 2- or 3-toothed at the apex, to 1.7 cm long and  0.6 cm wide, viscous, with raised glands, glabrous to puberulent, margin entire, unevenly sinuate or with very small regular teeth or lobes. Flowers solitary or rarely 2 together, axillary, sepals 4, stamens 8. Dodonaea intricata can be distinguished from D. viscosa subsp. cuneata by its solitary flowers and narrower, oblong, thicker leaves, usually with a truncate-emarginate apex. Flowering between February and March.
Fruit type:
Red-brown capsule 4-winged, to 13 mm long and 14 mm wide, usually glabrous, wings 2-4 mm broad, extending from the base to the apex of the capsule. 
Seed type:
Brown globular seed to 2.5 mm long and 2 mm wide, with a short brown aril.
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 low, at 40%.
Seed germination:
This species has physiological dormancy that needs to be overcome for the seed to germinate (e.g. nicking the seed coat).
