Alocasia scalprum

Samar lance

Alocasia scalprum is a compact jewel Alocasia endemic to the eastern Philippines. Its narrow, lance-shaped, thick and glossy leaves have sunken veins and a bluish sheen when mature. It grows as an understory herb on limestone in lowland evergreen rainforest, so it wants warmth, high humidity, shade and a very free-draining mineral mix.

Where it grows wild

A terrestrial herb about 0.5 m tall of lowland evergreen rainforest. A herbarium specimen from Dinagat records it as common, growing on limestone bedrock on a 10–30° slope; the leaves are thick and bullate, dark green above and purplish beneath. Like its close relative A. heterophylla, it appears to be a plant of lowland limestone forest.

Lowland. The only specimen with elevation data was collected at 79 m; no records come from higher ground.
