Name derivation:
Grammosolen from the Greek 'gramme' meaning a line or stroke of a pen and 'solen' meaning a pipe; alluding to the striated corolla tube. Dixonii named after Samuel Dixon (1841-1927), a naturalist and early environmentalist in South Australia and the collector of the type specimen.
Distribution:
Endemic to South Australia and found on the north-eastern Eyre Peninsyla, northern Yorke Peninsula and the Murray region, on deep sandy soils, often in disturbed mallee-spinifex associations.
Status:
Native. Common in South Australia.
Plant description:
Erect, spreading or sprawling shrub to 2 m high and 5 m diameter covered in greyish woolly hairs. Leaves ovate-triangular to subcordate, to 20 mm long and 17 mm wide, densely hairy, entire to undulate. Inflorescence sometimes forming leafy spikes with 1–3 dull-white with purple striations in the throat flowers. Flowering between August and January.
Fruit type:
Brown subglobular capsule to 4.5 mm long.
Embryo type:
Linear fully developed.
Seed collecting:
Collect capsules that are maturing, fat, turning a straw colour and contain hard brown seeds inside. Monitor the plants as the capsules will dry, split and disperse the seeds in a short space of time.
Seed cleaning:
Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently by hand or with a rubber bung 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.
