Chocolate Tea Tree Orchid

The Chocolate Tea Tree Orchid (Dendrobium johannis) is an epiphytic to lithophytic orchid in the family Orchidaceae, endemic to northern Queensland, Australia and southern Papua New Guinea. It belongs to the vast genus Dendrobium, one of the largest orchid genera with over 1,800 species across tropical and subtropical Asia, the Pacific, and Australia. Dendrobium johannis produces cane-like pseudobulbs bearing narrow, leathery leaves, and clusters of small to medium-sized flowers with creamy white to pale yellow petals and a lip marked with chocolate-brown to maroon blotches and stripes — a patterning that may serve to attract specific bee pollinators through visual mimicry or reward signalling. In the wild, the species grows on tea trees (Leptospermum, Melaleuca), paperbarks, and other trees in seasonal tropical woodland, gallery forest, and savanna margins in the Top End and Cape York regions. It tolerates distinct wet and dry seasons, losing some foliage during dry conditions. The IUCN classifies this species as Near Threatened, reflecting pressures including habitat clearing for agriculture, altered fire regimes, and collection for the horticultural trade. It is cultivated by orchid enthusiasts worldwide and has been used in hybridisation programmes.

koala

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。
