Census of South Australian plants (external link)     [genus Lawrencella]
Name derivation:
Lawrencella probably named after Robert William Lawrence (1807–1833), a settler in Tasmania who was recruited by W. Hooker in 1830 as a plant collector and sent specimens to Kew. Davenportii possibly named after Sir Samuel Davenport (1818-1906), one of the early settlers of Australia who became a landowner, parliamentarian and president of the Royal Agricultural and Horticultural Society in South Australia.
Distribution:
Found in the western half of South Australia, growing in mulga woodland on sandy loam soils and in mallee shrubland in sand dune areas. Also found in Western Australia and the Northern Territory.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Annual herb to 40 cm tall, usually with several erect unbranched hairy stems. Leaves basal on each stem, linear-oblanceolate to linear, flat, with a usually entire, sometimes shallowly wavy margin, to 140 cm long and 10 mm wide, hairy on both sides like the stems. Flower-heads solitary, on a long stalk with pink to white papery daisy flower. Flowering between July and October. 
Fruit type:
White fluffy head.
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect whole heads that are drying off and fluffy or collect just the seeds by plucking it off with your fingers. Mature seeds are easily removed.
Seed cleaning:
Place the heads in a tray for a week to dry. Then pluck the seeds from the head with your finders. Viable seeds will be fat and brown. 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 high, at 90%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
