Serious detective work by a team of experts has identified a new type of giant waterlily.
Botanists had long suspected that there were three types of giant waterlily, but it wasn't until seeds provided by two botanical gardens in Bolivia were grown in London's Kew Gardens that the new species was identified.
The new waterlily's part of the same Victoria genus as the existing Amazonica and Cruziana varieties.
It's been named Victoria Boliviana as the seeds came from Bolivia.
It's taken four years for the waterlily to reveal its true identity.
The team working on the project, anxious not to reveal their discovery too soon, kept the plant unlabelled but in plain sight.
The detailed research work of the botanists included DNA analysis.
For Carlos Magdalena, scientific and botanical research horticulturist, it highlights how little we know about our natural world.
Victoria Boliviana grows lilypads of over three metres in diameter and, curiously, its many flowers only open one at a time.
These blooms last for just two nights, turning from white to pink in the process, and are covered in giant prickles.

Kew Gardens is the only place in the world where all three species of giant waterlily can be seen growing together.
