- Abstract
A morphological (non-molecular) cladistic analysis of the Velloziaceae is presented. The terminal taxa are 47 species of Velloziaceae plus four taxa as outgroups:Acanthochlamys bracteata(Acanthochlamydaceae),Encholirium scrutor(Bromeliaceae),Thoracocarpus bissectus(Cyclanthaceae) andPandanus racemosus(Pandanaceae). The species of Velloziaceae sampled represent a significant proportion of the morphological diversity of the family, including all recognized genera and sections. The analysis revealed two major groups within Velloziaceae, supported mainly by stomata, vascular bundles in the pedicel, aquiferous tissues, filaments, anthers, pollen, stigma, seeds, ploidy and chemical characters. Comparison between this and the previous phylogenetic hypotheses for Velloziaceae, together with the two conflicting current classifications, suggests that there is incompatibility concerning the support of current genera and sections. The only three groups supported in all phylogenies are BarbacenioideaesensuMenezes (= Barbacenia sensuSmith&Ayensu),Xerophytasect.BarbacenioidesandXerophytasect.Xerophyta sensuSmith&Ayensu. © 2005 The Linnean Society of London,Botanical Journal of the Linnean Society, 2005,148, 157–173.
