Name derivation:
Pultenaea named after Richard Pulteney (1730-1801), an English physician, botanist and biographer of Carl Linnaeus. Insularis from Latin meaning pertaining to or growing on islands; referring to the species occurring only on Kangaroo Island.
Distribution:
Endemic to South Australia and found only on the eastern side of Kangaroo Island mainly in Beyeria Conservation Park,  growing on sandy-clay soil in open forest of Eucalyptus. and Melaleuca which has had several partial clearances.
Plant description:
Spreading to prostrate shrub to 60 cm high, rooting at nodes, with wiry branches that are green to reddish-brown, woody and hairy. Leaves elliptical, to 6 mm long and 3 mm wide, margin flat or recurved to revolute, with tip mucronate and recurved, green to dark-green, sometimes with a reddish tint, upper surface hairy. Inflorenscence solitary yellow pea-flowers to 5 mm long mainly towards the apex of branches. This species is very similar to P. pedunculata has larger flowers (to 8 mm long), longer narrow-lanceolate to narrow-elliptic leaves (12 mm x 3 mm) and nearly glabrous lamina ending in long-mucronate to an almost pungent straight tip. Flowering between November and December. 
Fruit type:
Hairy flat brown ovoid pod to 4 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.
