Plant description

Erect shrub to 1 m tall with glabrescent stems. Leaves oblong to ovate-elliptic, papillate, clustered or alternating along the stems, to 5 cm long and 26 mm wide, upper surface hairy becoming hairless, lower surface hairy, edges flat or curved down. Flowers purplish blue with a yellow throat, tubular, the tube split to the base, with 5 lobes, solitary or in groups of 2-9 flowers on 1-3 stalks arising at the bases of the leaves. This variety is distinguish from the other two varieties found in South Australia by its glabrescent stems, leaves oblong to ovate-elliptic, papillate and hairs outside corolla not appressed, tomentose with spreading dark-grey dendritic hairs, where as D. lanceolata var. intermedia have tomentose and not papillate stems, leaves oblong to ovate-elliptic, slightly papillate and hairs on outside of corolla loose, silky, pale grey and D. lanceolata var. lanceolata have glabrescent, papillate stems, leaves linear to oblong-elliptic, usually not papillate and hairs outside corolla tomentose with long dendritic or plumose grey hairs. Flowering between August and January. Fruits grey-tomentose cylindric to 5 mm long and 3 mm wide. Seeds black woody, oblong, with deep wrinkled surface. Seed embryo type is spatulate.

Seed collection and propagation

Collect seeds between October and February. Collect maturing fruits, those that are fat and contain hard dark seeds inside. Collecting good mature fruits will be time consuming as few fruits maybe produced. Place the fruit in a tray and leave to dry for two weeks. Then rub the fruits gently with a rubber bung to dislodge the seeds. Use a sieve to separate any 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. This species tend to produce very few viable seeds.
