During the last 12 years from the first publication of Tropical Garden Plants in Colour, readers suggested that separate books on 5 chapters would be easier to consult as a guide for a particular group of plants. This was considered meaningful as a suggestion providing scope for inclusion of illustrated information on more species of plants in colour from the photographs taken from tropical and subtropical regions in India, Australia and south-east Asia during the last few years. The collection of herbaceous foliage and flowering plants in Flecker's Botanic Garden, Queensland is excellent and photographs of a few species of Aechmea, Ettlinger, Zingiber, Heliconia, etc. have enriched this volume.
Colour illustrations of more than 500 species and varieties have been included in this edition and the books consulted and used for the preparation of manuscript of house plants are acknowledged in the 'Bibliography'.
