Anthurium alcatrazense

An Anthurium from southeastern Brazil, apparently endemic to the Alcatrazes islands off the São Paulo coast. There is almost no published detail on its habitat beyond its original description, and GBIF has a single record near sea level. Grow it as a warm-temperate coastal Atlantic forest plant with a mild, drier winter.

Where it grows wild

Habitat is undocumented in the sources reached. The single record is near sea level on a small, rocky, oceanic island, where exposed rock and low coastal forest dominate. The growth form is inferred from that setting, not confirmed.

One record at about 6 m; the elevation range is unknown.
