The research behind a taxonomic monograph: a case study from Ipomoea (Convolvulaceae)

Abstract

Systematic monographs are an important tool for understanding biodiversity. However, while papers that outline systematic methods for biogeography, phylogenetics and diversification are commonplace, papers that cover methods for monographic and taxonomic research are rare. In this paper, we describe how we conducted a monographic study of Ipomoea, drawing attention to the resources we made use of and the practical steps we took, with a particular focus on how we integrated results from molecular and morphological analyses. The monograph provided a framework for a range of subsequent research, including studies on the origin of the important crop sweet potato. It is hoped that our experience will provide a blueprint for others embarking on the preparation of a systematic monograph.
