Zamia ulei

An Amazonian lowland cycad recorded from Colombia, Peru, Ecuador, Brazil and Bolivia, mostly below 300 m. Treat it as a hot, humid forest-understory plant that never sees a cold or truly dry season; it is listed as Near Threatened, so grow only legally sourced plants or seed.

Where it grows wild

Recorded in lowland Amazonian rainforest; like its Amazonian relatives it is expected to be a terrestrial understory cycad of well-drained forest soils. Species-specific habitat notes are scarce, so this is inferred from the genus and the records.

0–730 m, median about 145 m; almost all records are lowland.
