Name derivation:
Dodonaea named after Rembert Dodoens (1517-1585), a Flemish physician and botanist, also known under his Latinized name Rembertus Dodonaeus. Subglandulifera from the Latin 'sub' meaning almost, below and 'glandulifera' means bearing little glands; alluding to the leaflets with glands on the lower surface only.
Distribution:
Endemic to South Australia and found on the east side of the Mount Lofty Ranges and on Yorke Peninsula, growing on low hills on loamy soils associated with rocky outcrops in open woodland, open shrubland and mallee.
Status:
Native. Very rare in South Australia
Plant description:
Dioecious perennial shrub to 2 m high. Leaves pinnate to 1.6 cm long, leaflets 9-17, linear, obtuse, entire or very rarely with 1 or 2 teeth near the apex, to 7.5 mm long and 1.5 mm wide, viscous, with raised glands on the lower surface only. Flowers usually 2 or 3 together, axillary, small yellow-gren flowers, sepals 3-4, stamens 6-8. Flowering between February and June.
Fruit type:
Red-brown three or four winged capsule, to 7 long and 15 mm wide, sparsely pubescent, wings extending from the base to the apex of the capsule.
Seed type:
Black ovoid seed to 3 mm long and 2 mm wide with a short brown aril.
Embryo type:
Folded.
Seed collecting:
Collect winged capsules that contain hard black seeds, usually when capsule is dry and dull red-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 three collections, the seed viability were average to high, at 50% to 90%.
Seed germination:
This species has physiological dormancy that needs to be overcome for the seed to germinate (e.g. nicking the seed coat).
