This was originally posted as Eucharis × grandiflora, but it was reidentified as Eucharis amazonica by Dr. Alan Meerow (see comments). Thank you, Alan!
If you’re a gardener, here is a factsheet on Eucharis.
The genus Eucharis is native to Central and South America. It has the sad distinction of containing a plant that has become extinct in the past one hundred and fifty years, Eucharis lehmannii.
Botany resource link: The Hebe Society web site not only features plants from the genus Hebe, but also a number of other plants from New Zealand. These include such rarities as the blue-pollened Fuchsia excorticata.
