Preface

Perhaps few regions of the world are comparable to South China with its characteristic karst mountain ranges, composed of thousands of small cone-shaped peaks. It is here that one can witness the highest diversity of plants in the Gesneriaceae family. One can encounter undescribed species whilst on holiday without the need to search. If actively looking for a rare species or genus, however, they may remain elusive even after exhaustive searches of known localities. The evolution of these plants has resulted in a complex morphology that can be difficult to interpret; plants with almost identical leaves possess distinct flowers and vice versa.

 

Foreword

The flora of China is particularly rich and diverse in Gesneriaceae. Owing to the late start of botanical studies in the 1920’s in China, early taxonomic work on Chinese Gesneriaceae was conducted by Western botanists. After that period, a few Chinese botanists began working on the family. In the 1940’s, Professor Chun Woon-Young, one of the founders of Chinese phytotaxonomy, studied the Gesneriaceae of South China and described several new genera and species, including the enigmatic genus Tengia Chun.
