Arisaema formosanum

A Taiwanese cobra lily of montane forest, recorded mostly between about 1,000 and 3,000 m. It grows from a tuber, leafs out with the spring rains and dies back for a cool, drier winter; treat it as a temperate-to-subtropical woodland geophyte.

Where it grows wild

Shaded and dappled forest floor and forest edges in Taiwan's mountains, in leaf litter over humus-rich soil. Habitat detail is inferred from the elevation records and the genus, as little is published for this species.

Records span 836–3146 m with a median of 1700 m, so it sits in cool montane forest rather than the lowlands.
