Common names

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. Angustissima from latin meaning very narrow or thin, referring to the leaves.

Plant description

Dioecious or polygamous-dioecious spreading or erect shrubs to 4 m high. Leaves linear to narrow-oblong, to 9.5 cm long and 0.4 cm broad, viscous, with flat glands, glabrous, margin entire to irregularly sinuate to irregularly denticulate. Flowers in terminal panicles with small yellow-green flowers. Sepals 3 or 4, stamens usually 8. Generally, the subspecies is readily distinguishable by its narrow linear leaves but many intermediates exist where two or more subspecies are sympatric. This subspecies differs from the other three subspecies found in South Australia by having the narrowest leaves. Flowering between September and January. Fruits are 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. Seeds are black, globular to 3 mm long and 3 mm wide with a short brown aril. Seed embryo type is folded.

Seed collection and propagation

Collect seeds between December and March. Collect winged capsules that contain hard black seeds, usually when capsule is turning red or brown with black seeds. 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 is usually high. This species has physiological dormancy that needs to be overcome for the seed to germinate (e.g. nicking the seed coat).
