Corymbia citriodora (Lemon-scented-gum) (Hook.) K.D.Hill & L.A.S.Johnson 1995

plant species in the myrtaceae family

It has smooth white to pink bark, narrow lance-shaped to curved adult leaves, flower buds in groups of three, white flowers and urn-shaped or barrel-shaped fruit.

Corymbia (Gum) K.D.Hill & L.A.S.Johnson 1995

plant genus in the myrtaceae family

Corymbia, commonly known as bloodwoods, is a genus of about one hundred species of tree that, along with Eucalyptus, Angophora and several smaller groups, are referred to as eucalypts. Until 1990, corymbias were included in the genus Eucalyptus and there is still considerable disagreement among botanists as to whether separating them is valid. As of January 2020, Corymbia is an accepted name at the Australian Plant Census.

Allocasuarina (She-oaks) L.A.S.Johnson 1982

plant genus in the casuarinaceae family

Allocasuarina, commonly known as sheoak or she-oak, is a genus of flowering plants in the family Casuarinaceae and is endemic to Australia. Plants in the genus Allocasuarina are trees or shrubs with soft, pendulous, green branchlets, the leaves reduced to scale-like teeth. Allocasuarinas are either monoecious or dioecious, the flowers never bisexual. Male and female flowers are arranged in spikes, the female spikes developing into cone-like structures enclosing winged seeds. The genera Allocasuarina and Casuarina are similar, and many formerly in the latter now included in Allocasuarina.

Persoonia terminalis (Torrington Geebung) L.A.S.Johnson & P.H.Weston 1991

vulnerable plant species in the proteaceae family

Two subspecies‍—‌P. t. terminalis and P. t. recurva‍—‌are recognised; both are found on well-drained acidic soils in sclerophyll forests, and P. t. terminalis is also found on granite outcrops. Although similar in appearance, they differ in leaf length and
