Cultivation

Nothing derived: no habitat climate for this species.

Climate across the habitat

No habitat climate can be derived: 11 in-range records, none placed to within 10 km. 11 of the 11 in-range records are 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 they count for the map and its marker.

Natural habitat

Native range as published by WCVP; the marker is where the records are densest and decides nothing.
No openly licensed record to show inside the range.

This species has no GBIF key of its own. Its records are GBIF's under the key of the name Kew's World Checklist holds as this plant: 10940008 (Isotrema thwaitesii (Hook.) X.X.Zhu, S.Liao & J.S.Ma, 14 records). No name was matched to GBIF; the keys are read from Kew's synonymy. How.

Kew's description“subshrub” · “subtropical” · quoted from WCVP, RBG Kew (CC BY 4.0); not derived here
Evidence usedThe map marker rests on all 11 georeferenced records inside the native range; none carries a licence permitting republication, so the map shows no points. 2 records outside the WCVP native range not used. Under a dozen records behind the map. No climate across the range is derived for this species. 11 in-range records are placed to worse than 10 km, or with no stated accuracy (admitted only as a person's observation to three decimals), and stay on the map but off the climate.
Other GBIF keysRecords also from GBIF's key 10940008 (Isotrema thwaitesii (Hook.) X.X.Zhu, S.Liao & J.S.Ma): Kew's file holds it as Isotrema thwaitesii (Hook.) X.X.Zhu, S.Liao & J.S.Ma (synonym under Aristolochia thwaitesii Hook.); 14 records, from GBIF's download.
How this section is made
The map marker: the centre of the tenth-degree cell nearest the middle (no openly licensed record lies in the population, so no record's coordinates are published) of the densest 1° population of the 11 in-range records; it decides nothing. Records outside the native range, living specimens and records marked introduced are not used; which records count.

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