Christmasbush

Christmasbush (Ceratopetalum gummiferum) is a small tree or large shrub in the family Cunoniaceae, native to New South Wales, Australia. It is perhaps the best-known plant associated with the Australian Christmas season, as its small white flowers are replaced in summer by persistent, enlarged, bright red sepals that give the plant a highly ornamental appearance around the Christmas period. The species grows naturally in dry to wet sclerophyll forests and woodlands on sandstone and related soils along the coast and tablelands of New South Wales. It is a popular cut flower and is harvested commercially and from private gardens throughout the state. The genus Ceratopetalum contains several species, all endemic to Australia and New Guinea. Christmasbush is also widely cultivated in gardens for its ornamental value. It plays a modest ecological role in woodland communities, supporting insects and birds. The species tolerates a range of soil conditions but generally performs best in well-drained, acidic soils. Its drought tolerance once established makes it suitable for low-water gardens. Harvesting of branches for the cut flower industry and garden collection has not significantly threatened wild populations, which remain widespread throughout suitable habitat in New South Wales.

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
