Name derivation:
Geranium from the Greek 'geranos' meaning a crane; alluding to the fruit resembling the head and beak of this bird. Retrorsum from the Latin 'retrorsus' meaning turned back or pointing backwards; referring to its petiole and pedicel which has distinctive long backward pointing (retrorse) hairs.
Found in the southern part of South Australia, growing in grasslands and grassy woodlands. Also found in Western Australia, Queensland, New South Wales, Victoria and Tasmania.
Native. Common in South Australia. Uncommon in Queensland. Common in the other states.
Plant description:
Decumbent to ascending perennial herb with stems to 50 cm long, with sparse to dense, short hairs. Leaves opposite, ovate to orbicular or reniform in outline, to 2 cm long and 3 cm wide, with hairs on either surface, deeply 5-7-lobed or dissected, each lobe divided into 3 narrow lobes. Flowers solitary or paired with bright pink to magenta petals. Flowering between June and February.
Fruit type:
Brown fruit to 15 mm long with 5 hairy mericarps.
Seed type:
Dark brown subglobular seed with deep depressions in the balloon part of the mericarp.
Seed collecting:
Collect matured fruit, those that are turning brown and the mericarps are starting to curl and peeling off the fruit stalk.
Seed cleaning:
Place the mericarps in a tray and leave to dry fro 1 to 2 weeks. If only the mericarps are collected, no further cleaning is required and it can be stored as is. Alternatively, you can clean to seed by gently rubber the mericarps with a rubber bung, then use a sieve to separate unwanted material. Store the mericarps/seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
