Morphogenetic information and the selection of taxonomic characters for raphid diatom systematics
Review – Morphogenetic data reveal that similar structures can be derived in different ways, and that dissimilar end-products may be produced by a single ontogenetic pathway. This paper discusses the importance of understanding valve morphogenesis before wall characters and character states are chosen and described, with particular reference to dorsiventrality, solid areas of silica, raphe and pore structure.
Conclusions – A better understanding of character formation will inform the use and development of terminology, which is critical to comparative studies and phylogenetic analyses of morphological data.

Plant Ecology and Evolution (a continuation of Belgian Journal of Botany, incorporating Systematics and Geography of Plants) is an international journal devoted to ecology, phylogenetics and systematics of all 'plant' groups in the traditional sense (including algae, cyanobacteria, fungi, myxomycetes), also covering related fields such as comparative and developmental morphology, conservation biology, ecophysiology, evolution, phytogeography, pollen and spores, population biology, and vegetation studies. It is published by the Royal Botanical Society of Belgium and the Botanic Garden Meise and contains original research papers, review articles, checklists, short communications and book reviews.
