Name derivation:
Plagiobothrys from the Greek 'plagios' meaning oblique or lateral and 'bothros'meaning a pit; alluding to the scar on the side of the mericarps. Plurisepaleus from the Latin 'plures' meaning several and sepal; referring to the species many sepals.
Distribution:
Found in the eastern half of South Australia, growing on sandy clay in damp flat at edge of creeks and claypan. Also found in all mainland states.
Status:
Native. Common in South Australia. Uncommon in Western Australia, Northern Territory and Queensland. Common in the other states.
Plant description:
Decumbent to procumbent annual herb with many branches mainly from the base, to 12 cm long, with flowers along the branches, with a tap root more or less densely covered with forward-directed appressed hairs. Leaves densely clustered, opposite and with a broad ciliate sheath at the base in a sparse basal rosette becoming scattered, alternate and without a sheath on the inflorescences, linear to linear-oblanceolate, to 45 mm long and 3 mm, usually bluntly acute, rarely rounded. Inflorescence terminal, with widely spaced small tubular white flowers. Flowering between June and November.
Fruit type:
Woolly fruit with 2 mericarps.
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect maturing fruits, those turning pale straw colour and contain hard seeds inside. Collect individual fruit or collect the whole plant.
Seed cleaning:
Place the fruits/plant in a tray and leave to dry for two weeks. Then rub the fruits gently by hand 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.
