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. Truncatus from Latin meaning abruptly cut off; unsure of what this is referring to.
Found on the Eyre Peninsula, northwest to the Gairdner-Torrens Basin and Nullarbor in South Australia, growing on deep sandy soils, commonly on sand dunes or localised sandy rises, usually on burnt or disturbed sites in mallee. Also found in Western Australia.
Native. Common in South Australia. Rare in Western Australia.
Plant description:
Erect shrub to 2 m covered in greyish hairs. Leaves mostly spreading, not overlapping or obscuring the axis, ovate to elliptic, to 18 mm long and 11 mm wide, densely hair, with a flat or slightly recurved margin. Inflorescence in leafy clusters with 1–3  dull-white with purple striations in the throat flowers. Flowering mainly between August and September.
Fruit type:
Brown globular capsule to 4.5 mm diameter.
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.
