Notes. The rhizome branches and forms large clumps in cultivation, which explains 
why it was almost impossible to remove it from the cracks in the limestone boulders 
of its natural habitat. The leafy shoots collected in the field were much longer than 
those of cultivated plants (75 vs. 40 cm) and had up to 20 leaves per shoot (vs. up to 
12) which were narrower. In 2015, only one of the plants in the glasshouses produced 
an inflorescence, which contained a total of 12 flowers usually opening late morning. 
Only one flower opened per day but sometimes there would be a day without flowers 
in between. 
ACKNOWLEDGEMENTS. The Davis Expedition Fund, Augustinus, and Blaxall Valentine 
Awards sponsored the expedition in Indonesia in 2009 during which the plant was discovered. 
The Sibbald Trust funded A.D. Poulsen as a Davis Research Fellow. The State Ministry of 
Research and Technology (RISTEK) issued the necessary permit. We are indebted to Helen 
Yeats, RBGE for keeping the plants alive, thereby enabling us to study the flowers and describe 
the species, and for making additional collections for herbaria. The Royal Botanic Garden 
Edinburgh (RBGE) is supported by the Scottish Government’s Rural and Environmental 
Science and Analytical Services Division. We thank J.F. Veldkamp and Philip Oswald for help 
in Latinising the epithet, Zou Pu for letting us include her pollen photos, Firdaus for travelling 
to the type locality to check the phenology, and Ida Theilade, Pramote Triboun, Bai Lin, John 
V 
Mood and Jana Leong-Skornickova for useful discussions. We also thank Susila and Hani 
Kharismantari for helping us in the Molecular Lab, Herbarium Bogoriense, Research Center 
for Biology, LIPI. Last but not least, the first author would like to thank the Sibbald Trust of the 
Royal Botanic Garden Edinburgh which allowed her to examine the herbarium specimens of 
Zingiber at E and K after the 10th Flora Malesiana Symposium.
