Name derivation:
Halgania named in honour of Emmanuel Halgan (1771-1852), vice-admiral of the French navy. Cyanea from the Greek 'cyaneos' meaning blue; referring to the blue flowers of the species.
Found across much of South Australia but mainly in the central parts, growing in mallee communities. Also found in all mainland states.
Native. Common in South Australia. Common in the other states.
Plant description:
Perennial shrubs to 60 cm high with many branches, more or less densely covered with hairs. Leaves usually sessile, entire to more or less toothed, usually oblanceolate to narrowly wedge-shaped or linear-elliptic, to 25 mm long and 5 mm wide, acute, obtuse or truncate, flat or folded lengthwise and more or less convex below, covered with appressed double-ended hairs. Inflorescence terminal with a number of clusters each with 1-3 bright-blue flowers. Sepals connate in the lower third or to half their length, equal, linear-triangular to lanceolate. Corolla rotate, usually bright-blue, with few double-ended hairs outside, with lobes ovate to lanceolate. Stamens with free filaments, inserted in the throat of the corolla tube, with anthers exposed in an erect column around the style, narrowly ovoid, with a terminal appendage, stiffly erect, hairy and particularly with hooked hairs on the inside. Flowers through out the year.
Fruit type:
Brown indehiscent drupe.
Seed collecting:
Collect fruits that are maturing, fat and hard.
Seed cleaning:
Place the fruits in a tray and leave to dry for two weeks. Then rub the fruit gently 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.
