El Valle Zamia
Newly described in 2013, this lovely small cycad is native only to low montane rainforest in El Valle de Antón, Panama between 600 and 1000 m, where it is considered endangered and only between 500 and 1000 adult plants are calculated to remain in the wild. It produces an underground trunk that gives rise to up to 5 leaves with large, glossy leaflets with long, narrow tips. Zamia nana has previously been confused with Zamia acuminata, a species now considered to be native only to Costa Rica. Zamia nana differs from Zamia acuminata in its smaller size, subterranean trunk and details of the cones. In cultivation it is best suited to tropical and frost free warm temperate regions.
