Name derivation:
Dicrastylis from the Greek 'dicroos' meaning forked and 'stylos' meaning a style; alluding to the deeply 2-branched style. Verticillata refer to the leaves and flowers arranged in whorls or seemingly so.
Distribution:
Found on the northern Eyre Peninsula and in the Murray region in South Australia, growing in mallee on deep red sand. Also found in New South Wales.
Status:
Native. Common in South Australia. Uncommon in New South Wales.
Plant description:
Low shrub to 65 cm high, stem grey-tomentose, with branchlets 3 at a node. Leaves 3 at a node, sometimes more, sessile, narrow-linear or linear-lanceolate, obtuse, with recurved margins, to 2.2 cm long and 4 mm broad, rugose and pubescent above, grey-tomentose beneath. Flower-spike terminal, arranged in verticillate clusters of 3 cymes per axil with white flowers, unequally 5-lobed. Flowering betwen September and December.
Fruit type:
White spongy ball.
Seed type:
Woody orange ovoid seed to 2.5 mm long and 2 mm wide, covered in hairs.
Seed collecting:
Collect mature fruits that are white and spongy. May need to collect a lot as most will not have any viable seeds. 
Seed cleaning:
Place the fruit in a tray and leave to dry for 1 to 2 weeks. Then rub the dried fruits with a rubber bung to dislodge the seeds. Use a sieve to separate any 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 low, at 10%.
