Name derivation:
Callistemon from the Greek 'kallos' meaning beauty and 'stemon' meaning a stamen, alluding to the beautiful flowers of the genus. Teretifolius from the Latin 'teres' meaning rounded and 'folium' meaning a leaf, referring to the leaves having a cylindrical cross-section.
Endemic to South Australia and found in the Flinders Ranges and the Mount Lofty Ranges growing on rocky hillsides, ridges and spurs in rough scrub.
Native. Common in South Australia.
Plant description:
Shrub to 1.5 m tall with fissured bark and rigid branches. Leaves rigid, terete, sharply pointed to 110 mm long and 1.5 mm wide, sometimes grooved below; oil glands few and scattered. Inflorescence a cylindrical spike to 70 mm long and 50 mm wide with flowers bearing crimson stamens and purple anthers  Flowering between October and December.
Fruit type:
Grey-brown, smooth, woody capsules to 7 mm long and 8 mm wide, valves constricted. Capsules remain on the branches.
Seed type:
Tiny brown rectangular seed to 1.5 mm long and 0.5 mm wide.
Embryo type:
Seed collecting:
Collect capsules that are large and hard with closed valves, preferably collect from older, woody capsules.
Seed cleaning:
Place the capsules in a tray and leave to dry for at least two weeks or until all the valves are open. Then place all the capsules into a bucket with a lid if possible and shake hard to dislodge the seeds from the capsules. Use a sieve to separate the seeds from the capsules. The fine material will contain the seeds and other flowering material. It is very difficult to separate the seeds from this other material as the size, shape and weight are very similar. However the seeds will be a darker brown and more fleshy looking. 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:
Seeds are non-dormant, viable seed should germinate readily.
