A war grower found in Guangxi, Hainan and Yunnan provinces of China, Hong Kong, the eastern Himalayas, Assam, Myanamar, Thailand, Laos, Cambodia, Vietnam, Penninsular Malaysia, Borneo, Java, Sulawesi, Sumatra and the Philippines. 2 groups, one with flowers lined up in 2 rows like this one while the other group of this 100 member genus has the flowers facing in all directions.
The inflos were complete almost 3 month ago. 4 weeks ago it opened one flower. As I waited for more flowers to open it faded after 3 to 4 days, no more flowers opened until today. I know better now and struck while the iron is hot and took pictures. It has a nice fragrance.
