New giant waterlily species reported in Colombia

The Guardian describes a discovery prompted by social media and says the plant is already considered critically endangered.

A social media encounter led to the discovery of a new giant waterlily species in Colombia's jungle, the Guardian reports. The item describes leaves large enough to be seen from space and says conservation plans are being developed for the plant, which is already considered critically endangered.

What holds up

  • ✓The Guardian explicitly reports a new species discovery in Colombia.
  • ✓The same item reports conservation planning and a critically endangered assessment.

What doesn't yet

  • ?No scientific paper, species name or formal conservation assessment is included in the supplied extract.
  • ?The claim about visibility from space lacks imagery or a definition of the observing conditions.

Ask before you share

  • →What published evidence establishes the plant as a distinct species?
  • →Who assessed its conservation status, and what population and habitat data support that assessment?
