Cultural significance

In Cambodia

The rumduol (Khmer: រំដួល), as it is known in Cambodia, is often planted in gardens and parks as it is valued for its fragrance. The flowers are used to make a scented lip wax called kramuon rumduol (Khmer: ក្រមួនរំដួល).[3] Several regions in Cambodia are named after this flower, such as Romdoul District and Ou Rumduol.

In a 2005 royal decree by King Sihamoni of Cambodia, the rumduol was proclaimed the national flower of Cambodia, however this decree references an invalid synonym for this taxon, Mitrella mesnyi.[3] The rumduol is often referred to as Popowia aberrans on botanical signs and as noted by Headley in the Cambodian-English dictionary.[4][5]
