Description

Leucopogon subsejunctus is an erect, open shrub that typically grows up to about 80 cm (31 in) high and wide with a single stem at the base. Its young branchlets are covered with straight, spreading hairs. The leaves are spirally arranged and point upwards, narrowly egg-shaped or narrowly elliptic, 3.0–8.5 mm (0.12–0.33 in) long and 1.0–2.5 mm (0.039–0.098 in) wide on a petiole 0.2–0.6 mm (0.0079–0.0236 in) long. The flowers are arranged in groups of three to eleven, 3–12 mm (0.12–0.47 in) long on the ends of branches and in upper leaf axils, with narrow egg-shaped to egg-shaped bracts and similar bracteoles 1.5–2.0 mm (0.059–0.079 in) long. The sepals are egg-shaped, 2.4–3.2 mm (0.094–0.126 in) long and tinged with purple near the tip, the petals white and joined at the base to form a bell-shaped or broadly bell-shaped tube 1.4–1.7 mm (0.055–0.067 in) long, the lobes 2.6–3.5 mm (0.10–0.14 in) long and tinged with pink. Flowering mostly occurs in August and September and the fruit is a deeply-lobed drupe 2.6–3.0 mm (0.10–0.12 in) long. [2]

Taxonomy and naming

Leucopogon subsejunctus was first formally described in 2014 by Michael Clyde Hislop in the journal Nuytsia from specimens he collected near Rocky Gully in 2008. [2] [3] The specific epithet (subsejunctus) means "somewhat separated", referring to "the remarkable morphology of the mature fruit which is so deeply lobed that the individual locules are almost completely separated from each other". [2]

Distribution and habitat

This leucopogon grows in woodland near Darkan in the Jarrah Forest bioregion in the south-west of Western Australia. [2] [4]

Conservation status

Leucopogon subsejunctus is listed as "Priority Two" by the Western Australian Government Department of Biodiversity, Conservation and Attractions, [4] meaning that it is poorly known and from only one or a few locations. [5]
