| Review (by Malcolm Storey) | The second edition is 25% larger than the first and includes more detailed coverage of subspecies and hybrids. The latter now follow one of the parent species rather than being listed at the end. After a brief introduction, the identification section starts with a brief review of the characters used. This is followed by the dichotomous Key to Genera, then the individual Genus entries, beginning with a short confirmatory description, then maybe a key to sections, followed by key(s) to species and subsprecies. The major portion of the book consists of detailed species accounts facing line-drawings of the whole plant or a stem, fruiting perianth, fruit, ochrae, perianth, etc. |
