Cover for In search of the true tree: guidelines for classification.

The central goal in cycad systematics is to uncover the 'true tree' that correctly represents the hierarchy of relationships within the Cycadales. Consensus reached at the Cycad Classification Concepts Workshop in Miami in April 2002 is that the cycads are a monophyletic group, that a species is...

Cover for Relationships and phytogeography in <i xmlns="http://www.w3.org/1999/xhtml">Ceratozamia</i> (Zamiaceae).

Species relationships and phytogeography of Ceratozamia, an endangered neotropical cycad genus, based on morphology, leaflet histology, DNA sequencing and ecological data, are analysed and discussed. Seven species complexes are assigned within the genus. A centre of origin in south-eastern Mexico,...

Cover for A morphometric analysis of the <i xmlns="http://www.w3.org/1999/xhtml">Ceratozamia norstogii</i> complex (Zamiaceae).

The three species forming the Ceratozamia norstogii complex (C. alvarezii, C. mirandae and C. norstogii) are found in adjacent areas of the Sierra Madre de Chiapas in Mexico. Taxonomic limits within this complex have not yet been fully defined, but are investigated in this project. Twenty...

Cover for Saving ghosts? The implications of taxonomic uncertainty and shifting infrageneric concepts in the cycadales for red listing and conservation planning.

A comparison of the cycad Red Lists from 1978 to 2002 shows that taxonomy has had a profound influence on the outcomes of the Red List process. The descriptions of new species, as well as taxonomic revisions, have increased the number of recognized cycad taxa from 136 in 1978, to over 300 at the...

Cover for Hypotheses on the relationship between biogeography and speciation in <i xmlns="http://www.w3.org/1999/xhtml">Dioon</i> (Zamiaceae).

Hypotheses are presented on the relationships between palaeoclimatic conditions during the late Pleistocene and Holocene, and the current biogeography of cycads in the genus Dioon. A proposal is made that Dioon populations have migrated up and down in elevation, and north and south, with the...
