Eucalyptus × conjuncta explained

Eucalyptus × conjuncta is a species of flowering plant that is endemic to a small area of New South Wales. It is a tree with rough stringy bark, lance-shaped adult leaves, flower buds in groups of eleven or more, white flowers and cup-shaped or hemispherical fruit. It is considered to be a stabilised hybrid between E. eugenioides and E. sparsifolia.

Description

Eucalyptus × conjuncta is a tree with rough, stringy bark on the trunk to the smallest branches. Young plants have leaves that are lance-shaped with finely scalloped edges, up to long and wide. Adult leaves are the same bright, glossy green on both sides, lance-shaped, long and wide on a petiole long. The flower buds are borne in groups of eleven or more on a thin, unbranched peduncle long, the individual buds on a thin pedicel long. Mature buds are oval to spindle-shaped, long and wide with a conical operculum about as long and wide as the floral cup. The flowers are white and the fruit is a woody cup-shaped to hemispherical capsule long and wide with the valves level with the rim or extending beyond it.[1] [2]

Taxonomy and naming

This eucalypt was first formally described in 1990 by Lawrie Johnson and Ken Hill from a specimen Hill collected from near the Murrurundi golf club. The description was published in the journal Telopea.[3] The authors noted that this appears to be a stabilised hybrid between E. eugenioides and E. sparsifolia and the name accepted by the Australian Plant Census is Eucalyptus × conjuncta. The specific epithet (conjuncta) is a Latin word meaning "connected" or "united",[4] in reference to the intermediate features of this species.

Distribution and habitat

Eucalyptus × conjuncta grows in woodland on poor soil usually on sloping sites and is only known from near Murrurundi.
