Androcalva from the Greek 'andros' meaning a male and 'calvus' meaning bald, hairless; referring to the glabrous staminodes present in this genus. Multiloba from the Latin 'multus' meaning many and 'lobus' meaning rounded projection; referring to the many serrated lobes on the margin of leaves of this species.

Endemic to South Australia and currently only known from two locations near Cowell on Eyre Peninsula, growing on reddish-brown, clayey sand over granite or white sand, in Melaleuca and Acacia shrubland, with scattered mallee and Triodia. Native. Very rare in South Australia.

Plant description

Erect, spreading perennial shrub to 50 cm tall. Leaves are dark green, wrinkled and covered in fine stellate hairs. Stems are covered in copper coloured hairs. Flowers are white with a red centre. Flowering between August and october. Fruits are brown globular capsule with four valves, splitting when matured and contain numerous black seeds. Seeds are small black tear-shaped seeds to 1.5 mm long, with small rounded projections on the seed coat. Seed embryo type is spathulate.

Seed collection and propagation

Collect seeds between October and November. Capsules can be collected prior to splitting as long as the seeds inside are hard and black. Place the capsules in a tray and cover with paper to prevent seeds being lost when explosively 'popping' out. Leave to dry for at least a week. Rub the dried capsules by hand to dislodge the seeds. Use a sieve to rub the fruits and to separate the unwanted material. Store the seeds with a dessicant such as dried silica beads or dry rice in an air tight container in a cool and dry place. From one collection, the seed viability was high, at 100%. These seeds have physical dormancy and can be germinated after pre-treatment such as scarification, nicking or hot water. The pre-treatments remove/breach the physical barrier for moisture uptake.
