Name derivation:
Petrophile from the Greek 'petra' meaning rock and 'philos' meaning lover; alluding to the species rocky habitat. Multsecta from the Latin 'multus' meaning many and 'sectus' meaning divided; referring to the many divided leaves.

Endemic to South Australia and found only on Kangaroo Island, growing on lateritic or calcareous sands, in sclerophyllous woodland and forest.

Native. Common in South Australia.
Plant description:
Small prickly shrub to 0.6 m or more high, with branchlets densely covered in grey hairs and reddish when young. Leaves divided many time, rigid, terete, to 8 cm long, glabrous, pungent tips. Inflorescence in the forks of branchlets consisting of dense ellipsoid cones of yellow flowers. Flowering between October and February.
Fruit type:
Greyish brown ellipsoid cone to 4 cm long.
Embryo type:
Investing.
Seed collecting:
Collect cones that are matured, turning brown, to ensure mature seed. Be care fully when collecting the cones as the plant is very prickly. Wearing gloves is recommended.
Seed cleaning:
Place the cones in a tray and leave to dry for 2 weeks. Then rub the dried heads with a rubber bung to dislodge the fruits. Use a sieve to separate any unwanted material. Seeds are enclosed in the hard fruit and can be stored as is. Store the fruit with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
