Name derivation:
Acrotriche from the Greek 'akron' meaning summit and 'thrix' meaning hair, alluding to the tuft of hairs at the tip the corolla lobes. Affinis from Latin meaning related or allied to or similar to another species.
Found in the southern part of South Australia, from the Nullarbor to the Murray River, growing on sandy soils in heath and mallee communities, and in clay swales between high sand dunes. Also found in Victoria and Tasmania.
Native. Common in South Australia. Uncommon in Tasmania. Common in Victoria.
Plant description:
Erect, much-branched shrub to 100 cm high, with young branches pale-grey or grey-brown and older stems grey. Leaves spreading or reflexed, broadly lanceolate, to 11 mm long and 2.5 mm wide, mucronate, flat to convex; glabrous, or scabrous above towards base, lower surface paler with unbranched subparallel veins separated by narrow, deep grooves. Flowers in a spike with 4-10 green, or green with  maroon-tinged flowers growing on previous season's or older wood. Flowering between August and October.
Fruit type:
Fleshy globular fruit to 4 mm long, white when ripen.
Embryo type:
Linear underdeveloped.
Seed collecting:
Lift branches carefully to locate the fruits. Collect berries that are turning creamy white and soft, with a hard seed inside.
Seed cleaning:
Place the berries in a bucket of water and rub the flesh off with your hands. Drain the water and wash again if required to remove all the flesh. Then spread the wet seeds on some paper towel and leave to dry. 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 is generally difficult to germinate, it has morphophysiological dormancy and complex germination requirements.
