Alocasia venusta

A small, rarely seen Alocasia known only from around the limestone Niah Caves in northern Sarawak, Borneo, where it grows on rock as a lithophyte. It has narrow, canoe-shaped leaves and is obscure even among Alocasia collectors. Grow it warm, humid and shaded in a very free-draining, mineral mix with some limestone.

Where it grows wild

A lithophyte on limestone in lowland rainforest around the Niah Caves. Plants grow in shaded, humid spots on rock and in pockets of humus over limestone, typical of the specialised limestone-endemic Alocasia of Borneo. No detailed field description of its microhabitat was found.

Niah is a lowland limestone massif, so the species grows at low elevation, probably below a few hundred metres. No specimen elevations were available.
