History W. van Deventer was based at Bandoeng long enough to pollinate the cross (1908), witness its first flowering (1919) before returning to the Netherlands, from whence he named the hybrid after his wife, Emma (1926).
...none of the several EVD used to make Nellie Morley came from van Deventer's original cross. All came from 1940s remakes in Hawaii. [Emrys Chew 03/12/2017]
