Summary

Nymphaea thermarum, also known as Miniature Rwandan water lily, is a species of water lily that is endemic to Rwanda. Once thought to be extinct in the wild, all wild plants were believed to be lost due to destruction of its native habitat, but it was thought to be saved from extinction when it was grown from seed at the Royal Botanic Gardens, Kew in 2009. A previously-unknown wild population was discovered in 2023.

Cultivation

Nothing derived: no habitat climate for this species.

Climate across the habitat

No habitat climate can be derived: 1 in-range record, none placed to within 10 km. 1 of the 1 in-range records is placed to worse than 10 km, or to no stated accuracy and fewer than three decimals or by something other than a person's observation, and cannot place a climate cell, though it counts for the map and its marker.

Natural habitat

Native range as published by WCVP.
Openly licensed records inside the range, framed on where they fall.
NativeRwanda · regions are the level-3 units of the World Geographical Scheme for Recording Plant Distributions, as Kew's World Checklist records ranges, some under historical names such as Yugoslavia or Czechoslovakia (how).
Kew's description“perennial or helophyte” · “wet tropical” · quoted from WCVP, RBG Kew (CC BY 4.0); not derived here
Evidence usedThe map marker rests on the one georeferenced record inside the native range, openly licensed and shown on the map. Under a dozen records behind the map. No climate across the range is derived for this species. 1 in-range record is placed to worse than 10 km, or with no stated accuracy (admitted only as a person's observation to three decimals), and stays on the map but off the climate.

Every source is recorded as having answered, reported nothing, refused, failed, not been asked, or answered twice where one answer is taken (“not taken: two items answered”), and, for a source asked when this page was built, when: the figures are as the source held them that day; a source read from a file (Kew's World Checklist, a GBIF download) says "as of" the file's day instead; a row carried from an earlier build of the page names that build instead. Only “nothing to report” is ever shown as an absence. Records came from 1 datasets via GBIF.org; each carries its own licence.
