Name derivation:
Pultenaea named after Richard Pulteney (1730 – 1801), an English physician, botanist and biographer of Carl Linnaeus. Hispidula means covered with minute stiff hairs or fine bristles.
Distribution:
Found in the southern Mount Lofty Ranges and the South-east in South Australia, with an old record from Kangaroo Island, growing in dry or moist woodlands and heathlands. Also found in New South Wales and Victoria.
Status:
Native. Rare in South Australia. Uncommon in New South Wales. Common in Victoria.
Plant description:
Small erect and spreading shrub to 1 m high with dropping branches covered in dense rusty-coloured hairs. Leaves alternate, oblong-elliptic or obovate, to 8 mm long and 3 mm wide, apex acute but not pungent, upper surface with a few scattered hairs, paler than lower, lower surface hairy, occasionally both surfaces glabrous. Flowers axillary clusters towards tips of short branches with yellow to pale-orange pea-flowers. Flowering between August and December.
Fruit type:
Hairy brown ovoid pod to 5 mm long.
Embryo type:
Bent.
Seed collecting:
Collect maturing pods, those that are brown or turning brown and contain hard seeds inside.
Seed cleaning:
Place the pods in a paper bag and leave to dry for one to two weeks. Then rub the pods with a rubber bung 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 physical dormancy that needs to be overcome for the seed to germinate. The seed coat needs to be ruptured so that water can enter the seed before germination can occur. Methods to rupture the seed coat include scarification with sand paper or nicking the seed coat with a sharp blade or hot water treatment by immersion in boiling water.
