A new edition of a now classic work, with the diagnostic notes on each species extended to provide much additional information on distribution, habitat and flowering times.  The number of colour photographs has been greatly increased to cover over 250 orchids, and line drawings of new species added in an appendix, while the bibliography has been refined to include the most essential references, with new entries accompanied by concise annotations.  This is still the one essential book for botanist, orchid enthusiast, ecologist, environmentalist and field worker who need to have the complete picture on Madagascar’s orchid flora.
