Lemon aspen, Acronychia acidula is a small- to medium-sized rainforest tree of the family Rutaceae native to north Queensland, Australia. The aromatic and acidic fruit is harvested as a bushfood.

Taxonomy[edit]

Victorian state botanist Ferdinand von Mueller described the lemon aspen in 1864.[1] Its species name acidula is Latin "slightly acid".[2]

Common names include lemon aspen, hard aspen and lemonwood.[1] The true aspens of the Northern Hemisphere belong to the genus Populus in the willow family Salicaceae.[3] The genus Acronychia is a member of the rue family Rutaceae, the same family as the genus Citrus which contains true lemons.

Ecology[edit]

The fruit are eaten by the Topknot Pigeon (Lopholaimus antarcticus).[4]

Uses[edit]

Lemon aspen fruit has a grapefruit and lime-like flavor, and is popular in beverages, sauces and confectionary. The fruit has high antioxidant activity.[5]

Cultivation[edit]

The tree is grown in small-scale commercial bushfood orchards on the east coast of Australia from North Queensland to northern New South Wales. The tree is quick-growing and requires regular pruning to maintain a practical harvesting height. It has a moderate crop yield, and bears in four years from seedlings. It prefers well-drained and fertile clay loam soils, with a sunny aspect and extra moisture when young.[2]
