Chrysoprase Mallee

The Chrysoprase Mallee (Eucalyptus repullulans) is a small, multi-stemmed mallee eucalyptus endemic to the southwestern corner of Western Australia. It grows in the mallee form characteristic of many Eucalyptus species in nutrient-poor, drought-prone environments: multiple lignotuberous stems arise from a swollen root crown (lignotuber), allowing rapid resprouting following wildfire or mechanical damage. E. repullulans typically inhabits sandy soils on heathlands and sandplains, often in association with kwongan vegetation dominated by Proteaceae and Myrtaceae. The species is assessed as Least Concern by the IUCN, suggesting stable populations not currently under acute threat. Like many Western Australian mallees, it produces small to medium-sized white or cream flowers that provide nectar and pollen resources for native bees, honeyeaters, and other pollinators. The lignotuber enables long-term survival and regeneration in fire-prone landscapes typical of the Australian Mediterranean climate zone. Mallee eucalypts are ecologically important as structural vegetation components in landscapes where taller trees cannot establish. Conservation of Eucalyptus repullulans is supported through the broader protection of Southwest Australian Floristic Region habitats, one of the world's biodiversity hotspots.
