Pilea bisepala

Pilea bisepala, described by Harold St. John in 1931, is a small Pilea of the southern Pacific: Rapa and Raivavae in the Austral Islands, and Rarotonga in the Cook Islands. Herbarium labels place it on summit cliff faces, so think cool, misty, wet rock rather than lowland forest.

Where it grows wild

Specimen labels from Rapa mention summit ridges and east-facing cliff faces; it likely grows on wet, mossy rock in cloud-swept vegetation.

Specimens from mountain summits and cliffs on Rapa, roughly 300–650 m; no elevations were measured here.
