A remarkable new species of giant waterlily, named Victoria colombiana, has been discovered in the Inírida River region of Colombia, a finding that underscores the rich biodiversity of the rainforest. The discovery was made possible through the unexpected confluence of social media, expert botanical knowledge, and the invaluable insights of local indigenous communities.

The journey towards this significant discovery began five years ago when U.S. horticulturist Jeremiah Harris posted photographs of intriguing waterlilies on Instagram. Initially, these images seemed commonplace, depicting Harris floating amidst the flora of the Inírida River. However, they caught the attention of Carlos Magdalena, a renowned horticulturist at the Royal Botanic Gardens, Kew. Magdalena suspected that there was more to these waterlilies than met the eye, as their known habitat did not include the Inírida region.
To investigate further, Magdalena employed satellite imagery to confirm the presence of what appeared to be Victoria waterlily pads in the area. He subsequently organised an expedition back to Inírida, collaborating with local horticulturist Mauricio Bernal and members of the indigenous Tucano community. Their goal was to locate and identify these mysterious waterlilies during a five-day exploration of the lush rainforest.
During the expedition, the team encountered challenges in identifying the plants, as they were unable to find any that were flowering. Flowers are essential for creating herbarium vouchers, which botanists rely on to differentiate between species. Despite their efforts, they were unsuccessful until the final day of the expedition, when a breakthrough moment occurred.
After expressing their frustration to their boatman Gustavo Melo, a local from the Tucano community, Melo revealed that he knew precisely where additional specimens could be found. Departing early in the dark, the team navigated deeper into the jungle before arriving at a small lake where they discovered five more individuals of the waterlily, crucially including one plant in bloom. This was the moment they had been waiting for, providing the evidence needed to formally describe their new species.
The exploration team successfully documented a total of seven waterlilies from two separate lakes before hastily returning to catch their flight, an inspiring outcome from their strenuous journey. According to experts at the Royal Botanic Gardens, Kew, Victoria colombiana is critically endangered, with estimates suggesting that only 30 to 50 specimens remain in the wild.
Magdalena reflects on this discovery as an extraordinary amalgamation of indigenous expertise, horticultural knowledge, and technological assistance through social media. He noted, “It is a reminder that nature is still full of surprises and wonder.” The urgency to protect this new species is palpable, with Magdalena stressing the importance of understanding and safeguarding it amidst the growing extinction crisis facing numerous plant species.
Maarten Christenhusz, a horticulture historian based in Wales, emphasised the rarity and significance of this new giant waterlily. He remarked, “New species are found all the time, but few are as large, spectacular, and emblematic as this one.” He added that its visibility from space highlights the vast unknowns about our planet’s biodiversity.
This discovery serves as a crucial reminder of the importance of preserving our natural world and the knowledge required to do so. As the scientific community continues to confront the escalating threats to plant species across the globe, the need for increased exploration and understanding of our environment has never been more vital.
In conclusion, the emergence of Victoria colombiana through an unexpected Instagram post exemplifies how technology, combined with local wisdom, can lead to groundbreaking scientific discoveries. The new waterlily not only enriches the world’s biodiversity but also calls for immediate action to ensure its survival against the backdrop of ongoing environmental change.
