Eucalyptus densa is a species of mallee or mallet that is endemic to Western Australia. It has smooth greyish bark that is shed in curly strips, linear to narrow lance-shaped adult leaves, long, spindle-shaped flower buds in groups of seven or nine, pale yellow or lemon-coloured flowers and conical, cylindrical or barrel-shaped fruit.

Description

Eucalyptus densa is a mallee or a mallet that typically grows to a height of 1–12 m (3 ft 3 in – 39 ft 4 in) and does not form a

capsule with the valves near rim level.[2][3][4]

Taxonomy and naming

Eucalyptus densa was first formally described in 1991 by the botanists Ian Brooker and Stephen Hopper and the description was published in the journal Nuytsia.[4][5] The specific epithet (densa) is a Latin word meaning "thick", "close" or "compact",[6]: 790  referring to crown of this species.[3]

Brooker and Hopper also described two subspecies and the names have been accepted by the Australian Plant Census:

  • Eucalyptus densa subsp. densa[7][8] - a short-trunked mallet with a dense crown, often to ground level;[4]
  • Eucalyptus densa subsp. improcera[9][10] - a mallee up to 3 m (9.8 ft) tall with slender stems.[4]

The subspecies name improcera is a Latin word meaning "short" or "undersized",[6]: 708  referring to its stature compared to subspecies densa.[4]

Distribution and habitat

This eucalypt is found on ridges, flats and drainage line areas of the southern

Ongerup, Ravensthorpe and Hyden and subspecies improcera in the Ravensthorpe and Jerramungup areas.[8][10]

Conservation status

Both subspecies of E. densa are classified as "not threatened" by the Western Australian Government
