Cycad classification: concepts and recommendations.

Book cover for Cycad classification: concepts and recommendations.

Description

This book presents the current state of our knowledge of the systematics of the approximately 300 species of cycads. It has been developed from 15 papers presented at the conference in Miami. Guidelines are presented for the designation of species, species boundaries and species groupings, thus clarifying what has been a confused area of research. Two appendices are included in this volume. The fi...

Chapter 14 (Page no: 173)

Zamiaceae of Bolivia, Ecuador and Peru.

Ten previously known species of Zamia from Bolivia, Ecuador and Peru are discussed and a new species from Peru, Zamia macrochiera, is described. Keys to all 11 species are given as well as complete descriptions, synonymy, types, exsiccata, distributional data and conservation status as used in the 1997 IUCN Red List of Threatened Plants. Zamia boliviana is found only in Bolivia and one collection from contiguous Brazil; Z. gentryi is endemic to Ecuador, while Z. macrochiera and Z. urep are endemic to Peru. The other seven species are more widespread, with Z. poeppigiana and Z. ulei found in both Ecuador and Peru; Z. disodon known from only one locality in Peru, in an area disjunct from northern Colombia; Z. hymenophyllidia found only in north-eastern Peru and contiguous south-eastern Colombia; and Z. roezlii found only in north-western Ecuador and contiguous south-western Colombia. Although widespread in the Amazon basin of Colombia, Venezuela and Brazil, Z. lecointei and Z. amazonum are each known from only one or two collections, respectively, in north-eastern Peru.
