Roebuck. Lanceolata from the Latin 'lanceolatus' meaning shaped like a lance-head, referring to the shape of the leaf. Intermedia from Latin meaning in between or Intermediate, possible alluding to the distribution of this variety occurring between the other two varieties.

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 tomentose and not papillate stems, leaves oblong to ovate-elliptic, slightly papillate and hairs on outside of corolla loose, silky, pale grey, where as 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 and D. lanceolata var. insularis  have glabrescent stems, leaves oblong to ovate-elliptic, papillate and hairs outside corolla not appressed, tomentose with spreading dark-grey dendritic hairs. Flowering between October and January. Fruits grey-tomentose cylindric to 5 mm long and 3 mm wide. Seeds dark brown to black woody, oblong to 4 mm long and 2 mm wide, with deep wrinkled surface. Seed embryo type is spatulate.

Seed collection and propagation

Collect seeds between December 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.
