The ginger genus Etlingera: diversity, distribution, and evolution

Axel Dalberg Poulsen, Ph.D.
Royal Botanic Garden Edinburgh, Scotland

The Indo-Pacific genus Etlingera (Zingiberaceae) exhibits a large  
morphological variation and contains more than 100 species many of  
which are useful as ornamental plants, food, spices or medicine. A  
complete revision of all species is still pending; only Peninsular  
Malaysia, Java and Borneo have been treated recently. The island of  
Sulawesi, just south of the Philippines, is currently being revised  
but more fieldwork is necessary before a satisfactory revision can be  
made for the Philippines, Moluccas, and New Guinea. DNA samples of the  
genus have been obtained from most of its distribution range from  
India through Malesia to the Pacific, except the Philippines. The  
genus is monophyletic with Hornstedtia as a sister grade and Wallace's  
Line seems to be a significant geographical boundary in the  
evolutionary history of Etlingera.
