Natural habitat

Native range as published by WCVP.
No openly licensed record to show inside the range.
NativeSri Lanka, Malaya · introduced: Jawa · 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“subshrub” · “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; none carries a licence permitting republication, so the map shows no points. 1 record outside the WCVP native range not used. Under a dozen records behind the map. No climate across the range is derived for this species.

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 2 datasets via GBIF.org; each carries its own licence.
