Eucalyptus × kalangadooensis

Eucalyptus × kalangadooensis is a species of tree that is endemic to a small area in South Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of between four and ten and top-shaped fruit. It is thought to be a hybrid between E. camaldulensis subsp. camaldulensis and either E. ovata or E. viminalis subsp. cygnetensis.

Description
Eucalyptus  × kalangadooensis is a tall tree with smooth bark. The leaves on young plants and on coppice regrowth are glossy green on both sides, broadly-shaped, up to 80 mm long, 40-50 mm wide and have a short petiole. Adult leaves are lance-shaped, glossy green on both sides, 80-140 mm long and 15-30 mm wide and have a petiole. The flower buds are arranged in leaf axils in groups of between four and ten on a peduncle 10-15 mm long, the individual flowers on a short pedicel. The mature buds are top-shaped, 10-12 mm long and 5-7 mm wide with a beak-shaped operculum about the same length as the floral cup. The fruit is a top-shaped capsule, about 10 mm long and 7-8 mm wide with the valves protruding above the rim.

The Australian Plant Census lists this species as a natural hybrid between E. camaldulensis subsp. camaldulensis and either E. ovata or E. viminalis subsp. cygnetensis.
