Amorphophallus macrophyllus

A little-documented Amorphophallus from southeastern Thailand and Vietnam. Like its relatives in the monsoon tropics, it almost certainly grows from a tuber that leafs out in the wet season and goes dormant in the dry season. Grow it hot and humid while in leaf, and keep the tuber dry and warm while it rests.

Where it grows wild

Probably the floor and edges of lowland seasonal forest, as with most mainland Southeast Asian Amorphophallus. This is inferred from the genus, since no habitat notes were found.

Lowland: the single site is at about 88 m. No elevations were recorded.
