Name derivation:
Hybanthus from the Greek 'hybos' meaning hump and 'anthos' meaning flower; referring to the spurred or pouched anterior petal. Monopetalus from the Greek 'monos' meaning single and 'petala' meaning petal; referring to the flower appearing to have only one large petal. 
Distribution:
Found in the east central part of South Australia with an isolated distribution in the north-east corner, growing on sandy soils or rocky outcrops. Also found in Queensland, New South Wales and Victoria.
Status:
Native. Common in South Australia. Rare in Victoria. Common in the other states.
Plant description:
Smooth perennial herb to 60 cm tall. Leaves alternate, the upper opposite or nearly so, linear to oblong, to 90 mm long and 4 mm wide, margins recurved, stipules linear to triangular to 1.5 mm long. Inflorescence axillary along a spike far exceeding the leaves with one large blue-mauve petal, lateral petals very small. Flowering between August and November.
Fruit type:
Pale green ovoid capsule to 6 mm long, with numerous seeds.
Seed collecting:
Collect capsules that are maturing, drying and turning pale green with dark seeds inside. Keep an eye on the capsules as they can ripen and split open quickly.
Seed cleaning:
Place the capsules in a tray and cover with paper to prevent seeds popping out and leave to dry for a week. Then rub the capsules gently  with your hands 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.
