Summary

Guizotia abyssinica is an erect, stout, branched annual herb, grown for its edible oil and seed. Its cultivation originated in the Eritrean and Ethiopian Highlands, and has spread to other parts of Ethiopia. Common names include noog/nug (Ethio-Semitic and Eritrean ኑግ nūg or ኒህዩግ nihyug); ramtil or ramtilla; niger or nyger seed (all pronounced , NY-jər); inga seed; and blackseed. Noug has been described as semi-domesticated, self-incompatible crop with yellow flowering heads and seeds. More on Wikipedia ›

Cultivation

Nothing derived: no habitat climate for this species.

Climate across the habitat

No habitat climate can be derived: Only 2 distinct land cells of the climate grid hold an in-range record placed to within 10 km; three are needed for an envelope. 11 of the 13 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.

Kew's description“annual” · “seasonally dry tropical” · quoted from WCVP, RBG Kew (CC BY 4.0); not derived here
Evidence usedThe map marker rests on all 13 georeferenced records inside the native range; the map shows only the 12 openly licensed ones, which alone would put the marker 26 km away. 1434 records outside the WCVP native range not used. 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.
How this section is made
The map marker: the openly licensed record nearest the middle of the densest 1° population inside the densest 2° block of the 13 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 105 datasets via GBIF.org; each carries its own licence.
