The Zamiaceae in Panama with comments on phytogeography and species relationships

Abstract

A key to, and descriptions of, the eleven species ofZamia in Panama are presented. Four of these are new species:Z. cunaria, Z. dressleri, Z. ipetiensis, andZ. neurophyllidia. Floristically,Zamia, is represented in Panama by three elements: three Central American species,Z. acuminata, Z. fairchildiana, andZ. skinneri, which reach their southern limits in central Panama; three northern South American species,Z. chigua, Z. manicata, andZ. obliqua, which reach their northern limits in Panama; and five endemic Panamanian species,Z. cunaria, Z. dressleri, Z. ipetiensis, Z. neurophyllidia, andZ. pseudoparasitica. These distributions are interpreted by a consideration of sister group relationships based upon derived morphological character states.
