Abstract

Zamia pyrophy Ha, a new species from Chocó, Colombia, is described and illustrated. It is compared to Z. amazonum, Z. cunaría, and Z.ipetiensis. It is distinguished by its bright orange and red emerging leaves with leaflets that progressively turn green from the apex to the base as they mature, petioles with branched prickles and with ferruginous pubescence when immature, villous strobilar axes, and adaxial microsporangia.
