Calathea oscariana

Calathea oscariana is a Guatemalan species described by Helen Kennedy in 2012 and known from very few collections. Its recorded sites sit near 1,300–1,400 m in a markedly seasonal climate, with a wet May–October and a dry November–April, which sets it apart from the ever-wet lowland Calathea.

Where it grows wild

A terrestrial forest-floor herb of mid-elevation forest in Guatemala. Its microhabitat is not described in sources reachable here; moist ravines and stream margins are the likely refuges through the dry season.

The climate sites sit at about 1,300–1,400 m; the records carry no elevations.
