Stenanona panamensis

Stenanona panamensis

Family: Annonaceae

Natural Range: Costa Rica, Panama

IUCN Conservation Status

Endangered (EN)

Stenanona panamensis is a member of the Annonaceae family and found in one of the most bio-diverse areas in the world, the forests of Central America. The species was first recorded in Panama, but has since been found at locations in Costa Rica. The tree is tropical therefore favours warmer humid climates, commonly occurring in primary forest along streams. The species was only discovered in the late 1990’s and is quite elusive so there is relatively little data on its characteristics. The species has quite an unusual flower; it produces a very delicate red specimen which is often cauliflorous, occurring at the base of the trunk.

Records show the first specimen was discovered by the Panama coast with the rest of the recorded individuals cited in Limon, Costa Rica. The species is very difficult to find and is suspected to live in small isolated communities, although there is hope to find further populations across Panama and Costa Rica. The main threat to Stenanona panamensis is habitat loss, although the future is bright as Costa Rica in particular is very conservation focused and recently reporting an increase in their forest cover. The species should be brought in to ex situ collections as a priority because of its Endangered status and its ornamental value.

This species is reported as held in 0 ex-situ collections.
