Alocasia atropurpurea

A large, critically endangered Alocasia known only from the Cordillera Central of northern Luzon in the Philippines, where the type was collected on Mount Polis in 1913. It has heart-shaped leaves about 40 cm long on petioles up to 50 cm, and a spathe with a deep purple-brown blade, which gives it its name. Almost nothing is published about its habitat, so these conditions are inferred from the Luzon highland climate and the needs of similar montane Alocasia.

Where it grows wild

Only two localities are known: Mount Polis on the Ifugao–Mountain Province border and an unspecified site in Mountain Province, both in the montane forest zone of the Cordillera Central. No habitat notes are published; like other large Philippine Alocasia it is presumably a terrestrial herb of the forest floor and shaded ravines.

Elevation is not recorded. Mount Polis rises to 1895 m and the road pass and forest there lie at roughly 1500–1900 m, so it is probably a lower-montane plant.
