Name derivation:
Bursaria from the Latin 'bursa' meaning a purse or pouch, referring to the capsule. Spinosa from the Latin 'spinosus' meaning thorny, referring to the spines that were present on the type specimen for Bursaria spinosa. Lasiophylla from the Greek 'lasios' meaning hairy or shaggy and  and 'phylla' meaning a leaf, referring to the dense white or greyish hairs on the underside of the leaves.
Distribution:
Found in the northern Flinders Ranges and Murrayland in South Australia, growing on heavier soils than the other subspecies. Also found in New South Wales and Victoria.
Status:
Native. Rare in South Australia. Common in the others states.
Plant description:
Tall shrub to 3 m high with hoary branches when young and occasional spines. Leaves alternate or clustered around spines, narrowly to broadly obovate, to 30 mm long and 10 mm wide, glabrous or glabrescent on upper surface, densely white, grey or yellowish beneath. Inflorescence a slender spike with white or cream flowers. Flowering between November and February. This subspecies differs from the other subspecies Bursaria spinosa ssp. spinosa which have glabrous leaves on the underside.
Fruit type:
Flattened ovoid capsules to 7 mm long and 8 mm wide, brown when mature and containing two seeds.
Embryo type:
Linear fully developed.
Seed collecting:
Collect maturing capsules individually or break off whole stems. The capsules should be drying off and turning brown with orange seeds inside. Do not collect capsules that have split open as the seed has already been released.
Seed cleaning:
Place the capsules in a tray, cover with paper and leave to dry for 1 to 2 weeks or until the capsules split. Then place the capsules in a bucket with a lid if possible and shake gently 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 one collection, the seed viability was high, at 100%.
Seed germination:
Viable should germinate readily when sown in winter.
