Summary

Schiedea adamantis, commonly known as Diamond Head schiedea, is a species of flowering plant in the family Caryophyllaceae, that is endemic to the island of Oʻahu in Hawaii. It inhabits low shrublands on steep slopes along the northwest rim of Diamond Head Crater. Associated plants include nehe (Lipochaeta lobata var. lobata), kāwelu (Eragrostis variabilis), ʻakoko (Euphorbia degeneri), and ʻilima (Sida fallax). There are only about 30 individuals remaining, and they are threatened by habitat loss.

Cultivation

Nothing derived: no habitat climate for this species.

Climate across the habitat

No habitat climate can be derived: 2 in-range records, none placed to within 10 km. 2 of the 2 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.
Openly licensed records inside the range, framed on where they fall.
NativeHawaii · 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“wet tropical” · quoted from WCVP, RBG Kew (CC BY 4.0); not derived here
Evidence usedThe map marker rests on all 2 georeferenced records inside the native range; the map shows only the 1 openly licensed one, which alone would put the marker 4 km away. Under a dozen records behind the map. No climate across the range is derived for this species. 2 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.
