The rarely acknowledged problem with hellebore species and its interaction with the bigger problem of defining what the term 'species' actually means, are confronted. A different approach to plant species classification is described and is shown to provide a solution to both problems.
"Overall, the book has a profound beauty. [...] of interest to any botanist."
– Paul Krause, Alpine Garden Society bulletin
"[...] the author has taken an innovative approach which I find increasingly persuasive as it does provide an answer to a problem that has baffled many. I do recommend this treatise to anyone interested in the classification of plants [...] ..as it presents an inspired way of looking at a particular problem where the traditional ways [...] have not provided a satisfactory answer. [...] copiously illustrated [...] but this is not a coffee table book, it needs concentration and repeated inspection."
– Brian Mathew, RHS Plant Review
