Name derivation:
Dodonaea named after Rembert Dodoens (1517-1585), a Flemish physician and botanist, also known under his Latinized name Rembertus Dodonaeus. Viscosa from the Latin 'viscosus' meaning sticky; alluding to the leaves being viscous. Mucronata from the Latin 'mucronatus' meaning pointed; alluding to the leaves ending abruptly in a sharp point.
Distribution:
Found in the far north-west corner of South Australia, growing on rocky hills and ranges and associated creeks and gullies in arid areas. Also found in Western Australia, Northern Territory, Queensland and New South Wales.
Status:
Native. Uncommon in South Australia. Common in the other states.
Plant description:
Erect to spreading shrub, to 4 m high. Leaves spathulate, sometimes obovate, mucronate, to 6 cm long and 2.5 cm wide, margin entire to irregularly sinuolate, viscous. Flowers in terminal panicles with small yellow-green flowers, sepals 3 or 4, stamens usually 8. Generally, the subspecies are readily distinguishable but many intermediates exist where two or more subspecies are sympatric. This subspecies differ from the other three subspecies found in South Australia by having leaves that end abruptly in a sharp point, similar to D. viscosa ssp. spatulata but found only in the north-west corner of the state. Flowering between September and January.
Fruit type:
Red-brown 3- or 4-winged capsule to 28 mm long and 28 mm wide, wings extending from the base to the apex of the capsule. 
Embryo type:
Folded.
Seed collecting:
Collect winged capsules that contain hard black seeds, usually when capsule is turning red or brown with black seeds.
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 germination:
This species has physiological dormancy that needs to be overcome for the seed to germinate (e.g. nicking the seed coat).
