Name derivation:
Asperula from the Latin 'asper' meaning rough, alluding to the stiff hairs on the leaves and stems. Conferta from the Latin 'confertus' meaning crowded, maybe alluding to the white 'posy' flower head..
Distribution:
Found in the south-eastern part of South Australia from the Flinders Ranges to the lower South-east growing in a wide range of habitats and soil types. Also found in Queensland, New South Wales, Victoria and Tasmania.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Erect to decumbent perennial, often slightly woody at base with slender stems to 30 cm long, sparsely covered in short hairs. Leaves in whorls of 5 or 6, linear to 12 mm long and 1 mm wide; acute to short-acuminate often with a short point; glabrous except for short hairs on margins and midrib on lower surface, margins flat to recurved. Inflorescences terminal or in upper axillary clusters with 1–3 white flowers, slightly shorter than or longer than leaves. Corolla 2–3 mm long on male flowers and 3 mm long on females; corolla tube slightly shorter than lobes. Flowering from September to November.
Fruit type:
Blackish-brown globular to reniform fruit, deeply lobed and rugose.
Seed type:
Green to brown reniform or concave seed to 1.5 mm long and 1.1 mm wide, with a wrinkled surface.
Seed collecting:
Collect maturing fruits by picking off the clusters that are fat and turning brown or break off stems with numerous fruit clusters.
Seed cleaning:
Place the fruits in a tray and leave to dry for one to two weeks. Then rub the fruits 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.
