Alocasia chaii

A small, robust Sarawak Alocasia of the A. scabriscula group, about 40 cm tall, with thick, almost succulent grey leaves that stay peltate even when mature. In the wild it has only a few leaves and grows on steep, litter-covered clay slopes in moist upper hill forest under light to moderate shade. It is rare in cultivation and wants warmth and humidity, but a mix that drains sharply.

Where it grows wild

Grows on steep to precipitous slopes of red clay-loam covered in leaf litter, under an open to fairly dense canopy of moist upper hill forest, in light to moderate shade.

The description gives its elevation only as upper hill forest in the foothills of Gunung Bukit Batu and the Hose Mountains. That is probably a few hundred metres to about 1,000 m, which is cooler than the lowland measured site.
