Description

Eucalyptus cadens is a spreading tree that grows to a height of 25 metres (82 ft) with a characteristic leaning habit, and forms a

capsule 3–4 mm (0.12–0.16 in) long and 4–6 mm (0.2–0.2 in) wide that is either sessile or on a pedicel up to 2 mm (0.079 in) long. The valves protrude beyond the rim of the capsule.[3][4][5][6][7]

Taxonomy and naming

Eucalyptus cadens was first formally described in 1989 by

Michael Crisp from a specimen at "the eastern foot of the Warby Range, between Wangaratta and Glenrowan".[8] The specific epithet (cadens) is the present participle of the Latin word cado meaning "to fall", hence "falling",[9] referring to the leaning habit of this species.[4]

Distribution and habitat

Tumble-down swamp gum grows in woodlands, often in or around springs, soaks and waterbodies in the south-eastern foothills of the Pilot Range near Beechworth and Wooragee and in the eastern foothills of the Warby Range.[4]

Conservation

Eucalyptus cadens is classified as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and the Victorian Government Flora and Fauna Guarantee Act 1988. The main threats to the species include grazing by domestic stock, weed invasion and changes in hydrology.[5][6]
