Christmasbush

Christmasbush (Bursaria spinosa) is a native Australian shrub or small tree in the family Pittosporaceae, widely distributed across southeastern Australia. The species is found in a variety of habitats including dry sclerophyll woodland, grassland margins, and coastal heath, growing in well-drained soils. It produces dense clusters of small, fragrant white flowers typically in summer or early autumn, which coincide with the Australian Christmas season and give rise to one of its common names. The flowers are rich in nectar and attract a wide diversity of insects including native bees, butterflies, and beetles, making Bursaria spinosa one of the most ecologically significant flowering shrubs in southeastern Australian woodlands for invertebrate communities. The plant is also a critical larval host for several butterfly species, including the rare golden sun moth. Bursaria spinosa is a pioneering species in disturbed landscapes and is used in revegetation and ecological restoration projects. Its dense, thorny branches provide protective nesting habitat for small birds. The species tolerates poor soils and periods of drought once established. It has no significant conservation concerns and is common throughout its range.

common greasewort

<em>Aneura pinguis</em>, commonly known as common greasewort, is a liverwort belonging to the genus Aneura within the family Aneuraceae. This cryptogamic plant inhabits ecosystems across Asia, Europe, and North America, thriving in moist or waterlogged environments. Its range encompasses Taiwan in Asia, six European countries, the United States in North America, and Brazil and Colombia in South America, indicating a broad geographic distribution across multiple continents. Common greasewort is assessed as Least Concern on the IUCN Red List. The species typically forms flat, ribbon-like thalli in damp habitats such as stream banks, wet rocks, and boggy ground. Biological traits of this species remain poorly documented in the scientific literature.
