Cultivation

Nothing derived: no habitat climate for this species.

Climate across the habitat

No habitat climate can be derived: 33 in-range records, none placed to within 10 km. 33 of the 33 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.
Openly licensed records inside the range, framed on where they fall.
NativeChina South-Central, China Southeast, Vietnam · 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).
Map marker23.161, 106.289 · in the densest population, 18 records (55% of those in range)
Kew's description“shrub or tree” · “subtropical” · quoted from WCVP, RBG Kew (CC BY 4.0); not derived here
Evidence usedThe map marker rests on all 33 georeferenced records inside the native range; the map shows only the 25 openly licensed ones, which alone would put the marker 145 km away. 1 record outside the WCVP native range not used. No climate across the range is derived for this species. 33 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.
How this section is made
The map marker: the openly licensed record nearest the middle of the densest 1° population of the 33 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 8 datasets via GBIF.org; each carries its own licence.
