NZ Myrtaceae Key - Online edition

Astartea fascicularis (Labill.) DC.


Common Names

false baeckea

Origin

Australia: south-western coastal regions of Western Australia.

Cultivation

Occasionally cultivated in New Zealand; recorded as naturalising into sand dunes near Whangamata but not found there recently.

Distribution

Scattered records from mainly urban areas in the North Island of New Zealand.

Distinguishing Features

Habit

Upright or spreading shrub, to 1.5 m tall.

Bark and Stem/Trunk

Bark thin, pinkish when young, older stems with brown smooth bark. Young stems pink-red in colour, with ridges or wings. Single or multi-stemmed.

Leaves

Adult leaves opposite, often bundled into clusters (fascicles), linear, 4–10(–12) mm long, 0.5–1 mm wide, same colour on upper and lower surfaces, slightly waxy; leaf blade flat, hairless and surfaces not puckered; margins entire; tips pointed; leaf stalks absent or ±1 mm long. Leaves give off a spicy fragrance when crushed.

Flowers

Flowers solitary in leaf axils (but the leaves are opposite, so flowers may appear ‘paired’ along the branches), flowers arranged facing upwards along the stems, ± 8–11 mm in diam., stalks long, petals 5, rounded, white to pale-pink, often tinged with a deeper pink at the base, and with a green eye; sepals 5, persistent, ridged, tips free, hairless; stamens 30–40, bundled into groups of 5–10, opposite sepals, white, shorter than petals. Main flowering period: summer to autumn.

Fruit

Fruit dry, 3-locular, 2.5–3 mm wide.

Similar Species

Erica lusitanica, Spanish heath, widely naturalised, is superficially similar in habit, and also with needle-like leaves to ± 10 mm long, but the flowers are small, tubular bells of fused light pink-to-white petals, unlike the broader, open flower with 5 free petals of A. fascicularis.

Notes

Astartea is a genus of 22 species endemic to south-western Western Australia.
