Description

Boronia jensziae is an erect shrub with many branches covered with star-like hairs and up to 2 m (7 ft) tall. The leaves are elliptic, 15–45 mm (0.6–2 in) long and 6–11.5 mm (0.2–0.5 in) wide on a petiole 2–4 mm (0.08–0.2 in) long. The flowers are pink to white and are usually arranged singly, sometimes in groups of up to three in leaf axils, on a pedicel 2–5 mm (0.08–0.2 in) long. The four sepals are about 4 mm (0.16 in) long, 2.5 mm (0.098 in) wide. The four petals are slightly hairy, 5.5–7 mm (0.2–0.3 in) long, 3–3.5 mm (0.1–0.1 in) wide but enlarge as the fruit develops. The eight stamens are hairy with those opposite the sepals longer than those near the petals. Flowering occurs from May to June and the fruit is a hairless capsule 4–4.5 mm (0.16–0.18 in) long and 2–3.5 mm (0.079–0.14 in) wide. [3] [2] [4]

Distribution and habitat

Andy Jensz's boronia grows in a variety of habitats including open forest and heath on the summit of Mount Bowman. It is only known from Hinchinbrook Island. [4]

Conservation

Boronia jensziae is listed as "least concern" under the Queensland Government Nature Conservation Act 1992 . [6]
