List

Leptospermum glaucescens, commonly known as the blue-green tea tree or smoky tea tree,[3] is a species of shrub or small tree that is endemic to Tasmania. It has elliptical to egg-shaped leaves that are often greyish green, white flowers about 15 mm (0.59 in) in diameter arranged in consecutive leaf axils and fruit that remain on the plant for some time after maturity.

Description

Leptospermum glaucescens is a shrub or small tree that has flaky bark and young stems that are hairy when young. It has elliptical to egg-shaped leaves with the narrower end towards the base, mostly about 10 mm (0.39 in) long, 3–6 mm (0.12–0.24 in) wide and often greyish green, tapering to a

capsule 4–5 mm (0.16–0.20 in) wide, remains on the plant for some time after maturity and has the sepals attached.[4]

Taxonomy and naming

Leptospermum glaucescens was first formally described in 1841 by

Berlin Botanic Garden, but extensive searches have failed to locate Schauer's type specimens. The neotype is "virgate shrubs to 3 m (9.8 ft) high dominating damp sandy heathland" at the western foot of the Strzelecki Peaks on the south-west of Flinders Island in Tasmania.[7]

In 1806, Jacques Labillardière described Leptospermum sericeum in Novae Hollandiae Plantarum Specimen from specimens collected "in capite Van-Diemen" and this name was applied to plants collected in Tasmania.[8][9] However, Labillardière had confused "Van-Diemen" with "Terre Van-Leuwin", and although he later made the correction on the herbarium sheet in Paris, the name L. sericeum continued to be applied to plants collected in Tasmania. Although in 1844 Johannes Conrad Schauer noted in Plantae Preissianae (in Latin) "in Van Leuwin's Land, not on Van Diemen's Island",[7][10] the correction was not made until 1967 with the publication of James Hamlyn Willis's paper in the journal Muelleria. Leptospermum sericeum is a Western Australian endemic, found near Esperance, which has pink, sessile flowers and does not grow to the height of L. glaucescens.[7]

Distribution and habitat

The blue-green tea tree grows in wet heath and is widespread in Tasmania.[4]
