Summary

Arfeuillea is a monotypic genus in the family Sapindaceae with Arfeuillea arborescens as its only species. Commonly known as hop tree, this species is characterized by compound leaves arranged spirally around the branches, flowers with small white petals and larger red sepals, and dehiscent papery yellow fruits with two black seeds encased. It is native to Laos and Thailand but is cultivated only and not found in the wild. The species serves as a street tree across its native range and in Malaysia and Singapore, and its antioxidant-rich leaves are included in many Thai herbal medicines.

Cultivation

Nothing derived: no habitat climate for this species.

Climate across the habitat

No habitat climate can be derived: 9 in-range records, none placed to within 10 km. 9 of the 9 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.

Evidence usedThe map marker rests on all 9 georeferenced records inside the native range, all openly licensed and shown on the map. 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. 9 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.

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.
